Welcome from the Head of School

Welcome to the inaugural School of Natural and Built Environments Postgraduate Research colloquium. I am delighted to introduce this, our first comprehensive demonstration of the range, scale and focus of the key research carried out by our outstanding postgraduate research students. The School was formed in 2004 following the merger of three former Schools and is now composed of four Disciplines with widely different teaching programs. Each of the four Disciplines (Civil Engineering, Construction and Project Management, Geospatial and Environmental Management and Urban and Regional Planning) focus on specific aspects of either natural or human constructed systems and all have active research programs within their themes. Most of our researchers thus work within one or other of the four significant research groupings which are being formalised within the University’s new research policy framework for research focus and concentration. Our four research groupings focus on issues related to sustainability of transport, water, urban ecology and building and planning. However, the School is much more than the sum of these discipline and research centre groups. Our School realises that the great discoveries in the near future will be at the interface between one or several disciplines. In the area of sustainable environments we are in a unique and timely position to develop more interdisciplinary research programs that cross traditional boundaries. NBE is embarking on a program to actively foster overlap between its Disciplines by encouraging multidisciplinary research around sustainability issues, and by promoting and encouraging interactions between researchers.

This colloquium represents one significant and important opportunity to develop collaborations between and amongst our most important group of researchers, our postgraduate students. PhD and Masters (by research) students are the “engine room” of the research program of any school because they produce the lion’s share of our cutting edge research. However, our postgraduate students also create the attitudes, ethos and research identity that defines the School because of the flair, enthusiasm and innovation they bring to our research program. However, it is not just their research talent that energises our research. Our students range in age from 25 to 60, and come from all walks of life. They come here from around the world and from a wide range of socio‐economic backgrounds. Hence our postgraduate students add a breadth and depth of “life experience” drawn from their varied backgrounds which influences not just their own research projects, but the nature and the style of our School research program. In a colloquium such as this, our students will hear and understand the

approach of others, influence and flavour the subsequent discussions with their own interests and attitudes and create long lasting relations with their peers that will form networks promoting research into the sustainable development and management of the natural and built environments for decades to come.

I congratulate the organising team and in particular the chief coordinator, Cathryn Hamilton for preparing such a wonderful, exciting and stimulating program demonstrating the breadth, depth and interactivity of the research conducted by the research students of the NBE School.

Welcome from the Dean of Research

The School of Natural and Built Environments Postgraduate Research colloquium is in its first year. The University of South Australia is developing the future directions for research concentrations. This is an ongoing process and getting the correct structure is vital, both for the research community within the University and also the University itself. Facilitating a fruitful working environment is the goal we all strive for. Inherent in that is developing both formal and informal collaborative structures. One method of promoting such collaborations is through presentation of one’s work.

One branch of my research has focused on renewable energy applications for many years. As is often said, it sometimes takes a long time to become an overnight success. I presented at conferences and workshops for many years as the sole mathematician at energy engineering events. That was because I wanted to build a presence among the researchers in that field. In this way, I built connections that I can now use to my advantage. I have encouraged all my postgraduate students to do likewise. A friend who is professor of mechanical engineering at Melbourne University refers to this initiative as he now takes his student to present. On a local scale, in the School of Mathematics and Statistics, a number of informal connections have arisen because the students have been presenting at School workshops wherein an unconnected staff member has become interested in the project. Two significant journal articles involving my students and myself have arisen in this manner.

I thus encourage you to make the most of this opportunity to display your research to incite your colleagues to comment on and possibly collaborate in your projects.

About the School

The School of Natural and Built Environments focuses on the unique relationships and synergies between natural and built environments, with a particular interest in teaching and research to support improved environmental and socio‐economic sustainability for the future. The School is located across two campuses – in the heart of Adelaide at the City East Campus and at the expanding and vibrant new suburb of Mawson Lakes on the northern fringe of the City. As part of the Division of Information Technology, Engineering and the Environment (ITEE), the School offers applied and relevant programs that take students out of the classroom and into the field. Civil Engineering Civil Engineering programs place particular emphasis on the application of theory through focused project and assignment work. By the final year of the degrees, fifty per cent of the courses are project based including a major industry related research project and a design project that models industry experience. This strong industry focus ensures that graduates are already familiar with the industry needs and modes of operation when they commence employment. The programs are accredited by Engineers Australia. Industry links include Department of Transport, Energy & Infrastructure (DTEI), SA Water and Built Environs ‐ all of whom provide scholarships for students in the program. UniSA coordinate regular industry lectures as well as industry sponsored student projects. Construction Management and Economics Construction Management and Economics at UniSA offers the only construction management degrees in South Australia and is one of the most accredited construction management and economics programs in Australia. Students can study a broad range of courses, including the study of sophisticated construction techniques, surveying and estimating, design economics, contract administration, project management, planning and more. All undergraduate and postgraduate programs provide the education and training required to reach a professional level and have a number of key industry links. The Bachelor of Construction Management and Economics program maintains a 100% employment rate. Environmental Management and Sustainability UniSA offers four specialised programs in the field of Environmental Management and Sustainability ‐ Biodiversity and Park Management, Environmental Protection and


ix

Management, Geospatial Information Systems, and Geographical and Earth Systems. All four awards provide students with a broad understanding of environmental issues and share a common first year, allowing the flexibility to move between the awards as career aspirations become clear. Graduates will be qualified to work in a wide variety of positions related to the natural and built environment and the multi‐disciplinary nature of the programs, as well as the strong focus on practical components of learning and active fieldwork, provides expertise in the natural, spatial and social sciences. Graduates are employed in the private and government sector in all Australian states and several overseas countries. Transport Systems Engineering The Transport Systems Engineering program is designed to provide Masters level expertise in the planning, designing and managing of transport systems and continuing education for graduate students with professional interest in the area of transport systems engineering and transport planning. The coursework enhances the concepts and theory in different aspects of traffic and transport engineering and students develop the capacity to undertake independent research and the ability to analyse and report on research procedures and findings. Urban and Regional Planning Urban and Regional Planning at UniSA is home to the longest‐established planning school in Australia and celebrates sixty years of planning education in 2009. Both the undergraduate and postgraduate programs incorporate a range of teaching techniques focused on providing students with the best possible conditions to advance their learning. Students undertake field trips, engage in collaborative projects, and are taught a number of professional skills courses by highly qualified planners. A work placement program has been built into the bachelors degree which provides students with an opportunity to work alongside qualified planners for an extended period of time. The Planning programs are strongly supported by the Planning Institute of Australia, the national body that accredits professional planners. There is also a strong ‘Young Planners’ group, which represents recent graduates and is closely linked to the student‐governed ‘Organisation of Planning Students’.

Project title: The characterisation of asbestos fibre bundles in asbestos cement.

Microprobe analysis of asbestos fibre bundles Abstract: Asbestos minerals vary widely in composition and physical properties, yet this variability has not been related to the risk related properties. This project investigates the breakdown of macroscopic asbestos fibre bundles to release respirable asbestos fibre, under ambient conditions. A first step has been fingerprinting of asbestos mineral materials. Early major element data from wavelength dispersive electron probe microanalysis is presented for samples of crocidolite and chrysotile asbestos from museum specimens from around the world. These data indicate that there may be compositional and mineralogical variations within asbestos mineral species that warrant further exploration as to risk related properties. Provisional data is sufficient for the selection of samples for further testing of fibre degradation. Major element chemistry may not be a sufficient fingerprinting tool for all asbestos but some asbestos mines are associated with signatures that are unique and may be discriminated with ‘major element’ analysis alone.

The role of cracking clay soils in maintaining biodiversity in South Australia’s rangelands and implications for sustainable management of arid zone landscapes

The role of cracking clay soils in maintaining biodiversity in South Australia’s rangelands and implications for sustainable management of arid zone landscapes

Abstract: The rangelands constitute most of the Australian continent. Pastoralism is the dominant commercial industry in these rangelands. Cracking clay soils are present throughout the arid rangelands. Based on preliminary research and literature, it appears that these clays may be important for maintaining rangeland biodiversity. This role and the effects of grazing on cracking clays have not been quantified. Research to determine the nature of this role is critical for the long‐term viability of rangeland industries such as pastoralism. We aim to determine the role of cracking clays in maintaining biodiversity in the South Australian rangelands. We will relate crack characteristics to shelter properties and species’ use, identify how the arid zone food web is influenced by cracking clays, compare productivity in terms of biodiversity between sites, and develop management recommendations that will apply to natural resource management organisations, private stakeholders, the pastoral and mining industries. This research has implications for sustainable rangelands management and biodiversity conservation in the arid zone.

Project title: Urban biodiversity enhancement using water sensitive urban design systems

Urban biodiversity enhancement using water sensitive urban design systems Abstract: Development of Water Sensitive Urban Design (WSUD) in Australia is rapidly changing the appearance of urban landscapes by incorporating engineered stormwater management systems such as bioretention basins. Despite these rapid landscape changes, little is known about their effect on urban biodiversity. The biodiversity potential of six bioretention basins and six corresponding paired greenspaces (divided into two subgroups) in the Melbourne area were compared using ground dwelling terrestrial invertebrates as biodiversity indicators. Overall, species composition was significantly different in these landscape types. The number of species, species richness and diversity displayed a decreasing trend from bioretention basins to garden bed and lawn type greenspaces. This trend may reflect the possible decreasing habitat resources. The differences in vegetation structure and biomass, pH, leaf litter depth and gravel were the main contributing habitat factors to the biodiversity of these landscapes. The transition from traditional urban greenspaces to bioretention basins has promise for urban biodiversity enhancement. Landscape planning at an urban design scale should consider reducing lawn areas as environmentally unsustainable urban greenspaces. At the streetscape scale, a combination of bioretention basins and garden bed type greenspaces may provide more ecologically sound and aesthetically pleasant streets in urban environments.

Carbon Dioxide Asset Management System (CO2AMS)

The Australian Electricity Atlas Abstract: The Australian Electricity Atlas is a presentation of all things spatial that are associated with electricity production in Australia. It is a look at the spatial distribution of electricity demand and consumption, assets and infrastructure, fuel resources, associated CO2 emissions, plus the challenges of the future with the impending introduction of the Australian Government’s Carbon Pollution Reduction Scheme (CPRS). The aim of the Atlas is to provide clarity as to the nature of electricity production in Australia and enable those involved in the industry to better understand the challenges associated with reducing CO2 emission from electricity production to meet the CPRS’s target of 60% less emission than 2000 levels by 2050.

Entrepreneurial governance and the green imperative

Entrepreneurial governance and the green imperative: a critique of the environmental (re)scripting of Port Adelaide and Mawson Lakes, South Australia

Abstract: This study falls within the broad context of large‐scale urban revitalisation. Examining both brownfield and greenfield developments within the urban context, the rhetoric of revitalisation draws upon a post‐industrial discourse that’s purported to be economically vital, socially empowering and environmentally progressive. While much urban regeneration literature has focused on the social and economic issues associated with large‐scale redevelopments, the environmental improvements purported by these developments are largely unexplored. Using the examples of the Port Adelaide waterfront redevelopment and Mawson Lakes, this research critiques the intersection of corporate environmentalism and entrepreneurial governance to reveal the processes through which key urban stakeholders mobilise an environmental discourse to promote and legitimise the rescripting and (re)development of underutilised urban landscapes.

Ecology of Fiji's bat fauna

Ecology of Fiji's bat fauna Abstract: Diet, seed dispersal, pollination, habitat use, and home range are key areas where no information is available for Fiji’s declining bat fauna. This study will describe the diet and habitat use of four bat species including pollination and seed dispersal roles (with detailed phenology of bat‐plants) and effectiveness as pollinators (e.g. compared to birds). I will monitor Pteropus camps and cave colonies of the primitive blossom bat (Notopteris macdonaldi), while conducting surveys to locate new caves. High altitude forests on the island of Taveuni will be surveyed for the critically endangered monkey‐faced bat (Mirimiri acrodonta). Local collaborators ensure findings are linked to long‐term conservation outcomes for Fiji’s bats.

Modelling of vehicle ownership and mode choice behaviour under motorcycle dominant environment

Travel demand modelling under motorcycle dominant environment Abstract: A massive use of motorcycles is a signature of Eastern‐Asian developing countries. This may be called a motorcycle dominant environment and it produces many serious transport issues to those countries. Travel demand modelling is a very useful tool used to examine transport issues. It is practical for exploring the traveller behaviours and demands, and also for predicting expected changes under different policy and planning strategies.

This presentation reviews previous studies on travel demand modelling under a motorcycle dominant environment, and discusses those findings. Results have shown that there are still large knowledge gaps found in those previous studies, especially regarding medium‐sized urban areas. This can be an inspiration for new research, and this will be discussed in the last section of the presentation.

Mechanisms for local government to support carbon neutral households

Mechanisms for local government to support carbon neutral households Abstract: The Australian Government and State Governments are variously setting targets for greenhouse gas (GHG) reductions which are to be achieved across various sectors including the residential sector. Local Government is increasingly getting involved in programs and initiatives to assist its Community to reduce GHG emissions. Little research has been undertaken across local government areas in Australia to identify the potential for reducing GHG emissions and the barriers which prevent this potential being achieved. The attitudes of key decision‐makers within local government is a potential barrier. The research is seeking to reveal the attitudes, behaviours and opinions of key decision‐makers in two local government areas across two states through their responses to various statements and questions. The research tools are explained together with their limitations. The outcomes of this research will inform the development of a toolbox of mechanisms for local governments to support households to become carbon neutral.

Groundwater recharge and evolution of the artesian water in Dalhousie, South Australia

87Sr/86Sr as indicators of the waterrock interactions in the Great Artesian Basin, Dalhousie, South Australia

Abstract: Studying the water‐rock interaction processes is important for proper groundwater resource management. The dissolved salts in groundwater come primarily from the atmosphere. The atmospheric components are then modified due to the interaction of the recharging water with the soil and aquifer rocks. 87Sr/86Sr represents one of the most successful tools of the water‐rock interaction studies. When water dissolves the rocks their Sr content transfers to the water without fractionation. This means that the ratio in that water is expected to be similar to that of the rock. However, not all the rock‐forming minerals have the same effect. In fact the effect of the minerals on the 87Sr/86Sr of the water depends mainly on the solubilities of these minerals. The great Artesian Basin aquifer at Dalhousie is composed mainly of quartzitic rocks with some traces of K‐feldspar and fewer amounts of kaolinite. Hence, the aquifer is chemically inert. The whole rock 87Sr/86Sr ratios range from 0.7461725 to 0.7537825 whereas the groundwater ratios range from 0.7092634 to 0.7184 which are quite low compared to those of the whole rock. The ratio of the aquifer trace carbonate content is 0.7233788 which is also higher than those of the groundwater. The 87Sr/86Sr ratio measured in the coal seams collected from the production zone of the Junction well have 87Sr/86Sr ratio of about 0.7153588 which is very similar to this well’s groundwater ratio (0.7151959).

Vulnerability analysis of road networks

Vulnerability analysis of road networks: a case study of the urban road network of metropolitan Adelaide

Abstract: Vulnerability analysis has been an area of increasing interest and research since the mid 1990s. There have been a number of main events that have disrupted transport networks around the world, but there are also everyday events that can cause delays and diversions. Vulnerability analysis is relevant as it is important that people can travel for work or recreational activities and is vital that emergency services have access to wherever they are needed. This presentation will discuss the proposal for this project, focusing on what research has been done and the methodology that will be employed. The project will analyse current measures of vulnerability, then define a new measure taking into account important aspects of each. This measure will be applied to the urban road network of Adelaide and consider two case studies; the South Road / Anzac Highway underpass construction and bushfires in Mount Barker.

Geotechnical investigation of interactions between civil infrastructure and street tree root systems

Interactions between civil infrastructure and street tree root systems Abstract: Tree root structures will be examined through excavation of mature specimens of Callery pear (Pyrus calleryana) and Grey box (Eucalyptus microcarpa). Field trials will be established to allow monitoring of tree growth (above and below ground) and root depth in relation to soil conditions beneath footpath designs including standard block paving, permeable paving with 150mm porous base, permeable paving with 300mm porous base, and permeable paving with 300mm deep porous base and additional moisture supplied via stormwater harvesting. Quarterly monitoring for three years will enable comparative assessment of the potential of each design to minimise or avoid root damage to footpath surfaces and to sustain the health and vigour of urban trees. Monitoring of soil moisture and soil movement at the trial sites will enable effects of increased and localised soil moisture to be observed and compared with existing infrastructure where moisture infiltration is minimal.

Integrated intelligent transport systems for urban traffic management

Integrated intelligent transport systems for urban traffic management Abstract: Intelligent Transport Systems (ITS) have become one of the efficiency tools for use in modern traffic management. Especially in urban networks with high levels of congestion and restrictions on road capacity, there is less opportunity to build new infrastructure because of restricted land availability and high construction costs. This paper aims to review the use of ITS for urban traffic management, discuss congestion management focusing on the surface street network in an urban area, and present the initial stage of the proposed research on using integrated ITS for urban traffic management. The proposed research is developing by considering three main issues in urban congestion traffic management: 1) finding a cost‐effective basis for Advance Traffic Management System (ATMS), 2) using Advance Traveler Information System (ATIS) as a control approach for demand management and 3) integrated ATMS and ATIS for urban traffic management as a supervisory system for urban traffic congestion management by considering network reliability performance.

Housing pathways for African refugees in Australia: towards an understanding of African refugee housing issues

Housing pathways for African refugees in Australia: towards an understanding of African refugee housing issues

Abstract: African migration to Australia has increased significantly since 2000, due to political unrest and civil wars on the African continent. Recent studies of African migrants have focused on mental health and education issues with modest or no reference to how housing problems matter for durable settlement of African refugees, or the relation of housing to health and education. Housing affordability is a major concern for all Australians but especially for the newly emerging African community. This research explores the predicament of African refugees as Australia faces a profound decline in housing affordability. The research seeks to examine the current and future housing needs of African refugees in relation to family size, transport, work, health, education, community integration and income. Most African refugees come from low socio‐economic status backgrounds and many depend on social security payments. In many cases their ambitions for suitable housing are untenable. This research draws on communicative planning theory and a case study methodology to engage with African refugee settlement experiences. The methodology for this research is a case study of African refugees in South Australia. The research is seeking a sociological understanding of African housing issues to inform creative policy options for settlement planning.

Emissions trading schemes for transport

Emissions trading schemes for transport Abstract: Road transport contributes around 87% of all transport GHG emissions and there are projections for higher increases in commercial road transport into the future. However, avoiding the devastating consequences of global warming requires reversal of this trend for transport GHG emissions growth. This is a challenging problem because currently 99% of transport energy is from fossil fuels and there are no widely available or competitive sustainable alternatives for transportation. Implementation of research and development outcomes for clean transportation should start now for successful management of transport GHG emissions. It is quite unlikely, that the market mechanisms of the proposed Carbon Pollution Reduction Scheme (CPRS) will significantly stimulate clean vehicle technology development. My thesis investigates how other types of schemes could effectively stimulate R&D and their role in future transport policies for management of transport GHG emissions.

Methodologies to maintain pre‐urbanisation low flow characteristics in an urbanised catchment

Methodologies to maintain preurbanisation low flow characteristics in an urbanised catchment using Water Sensitive Urban Design measures

Abstract: Rapid urbanisation processes significantly alter the natural hydrological cycles and cause deterioration in both the forms and the functions of aquatic ecosystems. Hydrological changes resulting from urbanisation include lowered groundwater levels due to reduced infiltration of rainfall/snowmelt into the subsurface areas. These lowered subterranean water tables result in reduction of the flow drained to local streams or lakes thereby affecting the low flow regime in streams particularly during dry weather periods. Low flow regimes are useful hydrological indicators for assessing the health of an aquatic ecosystem. Environmental flows are necessary for rivers and streams to sustain the natural river ecosystem generally associated with the low flow regime. Therefore maintaining the natural low flow regime of a stream is a primary goal to protect environmental values and maintain the aquatic ecosystem health. This study focuses on investigating the performance of possible Water Sensitive Urban Design (WSUD) measures to maintain the pre‐urbanised status of the low flow regime in a post‐urbanised catchment.

The evolution of urban transport policy in Australian cities and the nature and rationale for current strategies

The evolution of urban transport policy in Australian cities and the nature and rationale for current strategies

Abstract: The research is investigating the nature of urban transport policy in Australia as reflected in published urban transport strategies. It has reviewed transport strategies for each major capital city in the period since the mid‐1960s. Some of these transport strategies are embedded in, or co‐released with, broader urban development strategies. Consideration has been given to the occasion and nature of the strategies, and the evolution of urban transport policy over the period. The research is examining current urban transport policy in more detail. Three surveys have been undertaken to provide insights into the understandings and views that underpin current urban transport policy and attitudes to the policies. The surveys have covered public servants in the policy and strategy divisions of almost all transport agencies in Australia, politicians in all state and territory parliaments, and the public in Adelaide and Sydney. Questions in the surveys allow comparisons to be made of the views of these groups who have a bearing on urban transport policy. The research is primarily based on theories of personal choice and public choice theory. Notes:

Modelling of unsteady flows in siphonic Roofwater harvesting systems

Modelling of unsteady flows in siphonic roofwater harvesting systems Abstract: Siphonic roof harvesting drainage depends upon the establishment of full bore flow within the pipe network linking roof collection outlets to a water storage tank or to the storm drainage system. The replacement of conventional multiple downpipes by a network of closed conduits offers significant advantages to the building designer, as evidenced by the increasing installations of such systems in buildings such as airport terminals, large warehouses and prestige office developments. While Siphonic systems have been in existence for approximately 30 years, there are few recognised design standards, and system design is generally based on steady state calculations which assume a near instantaneous steady full bore air‐free flow within a single outlet siphonic roof drainage system. The proposed research aims to develop an unsteady flow model that incorporates time‐varied form loss coefficients within the pipe system. The purpose of the model is to simulate an idealised siphonic roof water harvesting system driven by a time‐varied storm hyetograph. The inflow to each siphonic outlet will be modelled using spatially varied flow analysis. This will be integrated into the unsteady pipe flow analysis to create a model to completely analyse the building drainage from rainfall to discharge.

Organisational participation in Geospatial Information Systems: a case study of the Australian Indigenous Land Corporation

Organisational participation in Geospatial Information Systems: a case study of the Australian Indigenous Land Corporation

Abstract: The overarching theme of the research is to encourage further geospatial participation within organisations. The research will focus on the Australian perspective in Indigenous land acquisition and management and, in particular the work of the Indigenous Land Corporation (ILC), but it will draw on experience from similar regional, national and international experiences. Through engagement and recommendation of the ILC, the research will initially embark upon a review of ILC business processes focusing on the level of geospatial activity. A value stream will be established for each process to determine both the temporal length of the process as a whole and each individual stage within. The examination then will deepen to probe each stage aiming to ascertain the major and minor activities that contribute to the business process. On completion on this phase, it is proposed that the research split into two avenues. Firstly, an investigation will take place assessing the spatial components of the process and secondly, identify opportunities in the aspatial environment. The research will endeavour to complement these efforts, existing geospatial research and also identify new avenues of exploration discovering where major gains can be realised. Secondly, the aspatial elements will be scrutinized to ascertain the opportunities for the incorporation of geospatial activities within previously text based realms. The research will conclude by indicating the extent by which the ILC can increase its efficiency by incorporating more geospatial components into their decision making processes.

Direct seed mix and tubestocking treatments for degraded agricultural land restoration

Direct seed mix and tubestocking treatments for degraded agricultural land restoration, Pt. Wakefield, South Australia

Abstract: Efforts to revegetate vacant agricultural land have been increasing globally, but there are still very few peer reviewed publications. This proposed thesis compares the success of sowing an agriculturally degraded semi‐arid site with a low‐ and a high‐diversity native seed mix for restoring biodiversity, community structure, and ecological function. The effect of boosting the diversity of a seed mix by planting tubestocked species to re‐create specific communities is also examined. The aim of the project is to determine whether the treatments are successful at restoring agriculturally degraded sites to a state similar to that of neighbouring remnant ecosystems and comparable to that of previously revegetated sites. To measure the success of the various seed mix treatments and tubestock combinations for restoration various ‘bio‐indicators’ will be compared. These bio‐indicators have been selected for their important role with regard to ecosystem function, and include: the density, percentage cover, frequency and species richness and diversity of vascular plants; the abundance and species richness and diversity of invertebrates; the % frequency of root colonization of native plant species by mycorrhizal fungi; and various soil properties including grainsize, organic carbon content, PH., salinity (conductivity) and levels of available nitrogen, phosphorus, potassium, magnesium, manganese, calcium and sulphur.

Integrating Transit‐Oriented Development and affordable, energy efficient housing

Integrating TransitOriented Development and affordable, energy efficient housing

Abstract: In the context of urgent global environmental challenges and a nationwide, multi‐causal housing affordability crisis, my proposed research aims to shed light on how locating energy efficient, affordable housing within pedestrian friendly, amenity rich centres or hubs along transport corridors could contribute to ameliorating these problems. Through efficiencies in transport use, innovative urban design and energy efficient construction, Transit‐oriented Development (TOD) has the potential to reduce emissions and increase resilience to climate and energy challenges, as well as ensure a diverse range of lifetime affordable, desirable accommodation. The research draws on three distinct fields: TOD, housing affordability and environmental sustainability. However, it is the intersection of the three fields which appears to provide a gap in both the literature and practice of urban planning. By integrating the three areas of knowledge and practice I hope to devise a planning framework for liveable, sustainable communities.

Exploring the intimate relationship between State Conformance to the International Civil Aviation Organisation’s standards, and safety in International Civil Aviation

Exploring the intimate relationship between State Conformance to the International Civil Aviation Organisation’s standards, and safety in International Civil Aviation

Abstract: In the interests of global safety, each member state of the International Civil Aviation Organisation (ICAO) undertakes to collaborate in securing the highest practicable degree of uniformity in standards with regards to aircraft, personnel, airways and auxiliary services that will facilitate and improve international aviation safety. Despite this undertaking it is evident from accident data reports from around the world that safety levels differ among member states. Also noticeable is the differences in levels of conformance of the member States to the ICAO Standards. This thesis examines the implicit relationship between state conformance to the international civil aviation organisation’s standards, and safety in international civil aviation, firstly to ascertain whether it is possible to demonstrate a relationship and secondly to determine the degree of complexity underpinning the relationship.

Travel time variability and reliability in order to measure road network vulnerability

Travel time variability and reliability in order to measure road network vulnerability

Abstract: The great demand for just‐in‐time and emergency services as well as the massive programs to relieve congestion in order to improve mobility and accessibility in urban areas have forced a great interest for a transportation system reliability and road network vulnerability study. Based on the literature, previous studies appraise road network vulnerability by measuring the increase of travel time, travel cost as well as accessibility index reductions. However, there is limited study about the individual loss (accessibility to participate in activity) due to the impacts of travel time variability and reliability. This study will assess specific corridors of the Adelaide metropolitan area road networks and measure the travel time variability to find out the travel time reliability. After measuring the travel time reliability, buffer time (amount of time which is needed to arrive on time) can be calculated. According to previous studies, most of the accessibility measurements were calculated based on the average travel time and did not quantify the travel time reliability which is presented by the buffer time.

Operation Possum

Possums in Adelaide: friends or foes? Abstract: Possums are a valuable part of Adelaide’s natural heritage. There are two large species that are found around the city, the brushtail and the ringtail. The brushtail possum has recently been listed as Rare in South Australia, with numbers declining in regional areas. However, brushtails are considered urban adapters and they thrive in urban environments. Therefore, the city provides an important refuge for the brushtail possum. Conservation of wildlife in urban areas can be problematic, especially when the species behaves in ways that disturb or distress people, as brushtail possums certainly do. At night they can be noisy as they cross within and above roofs and make loud cough and hiss noises in defending their territories. They can cause damage to houses and gardens, staining ceilings and walls with urine and eating fruits and leaves from ornamental and fruit trees. Operation Possum is a Citizen Science research project. An internet‐based questionnaire is being used to gather information on possums in South Australia, including wildlife management techniques and people’s attitudes towards possums. The information gathered will give us a better understanding of how people feel about possums that live around them: are possums friends or foes? Notes:

Developing Fuzzy‐Neuro model for travel demand modelling

Developing FuzzyNeuro model for travel demand modelling Abstract: Various methods are currently used in travel demand modelling (TDM), for example, the Four‐Step model (which is widely used and is perhaps the most famous one), Activity Based Approaches (ABA), Discrete Choice Models, Fuzzy Set Theory and the Neural Network Approach. The emergence of these different methods is due to, for instance, different areas having different problems. Hence, a method successfully applied in one area could be unsuitable for use in others. The literature suggests possible errors of the order of 60 per cent between different travel demand modelling methods. The sources of errors are not only from a lack of information related to the parameters that the model tries to estimate but also due to the absence of sharply defined criteria of class membership that can play important roles in human thinking, for which qualitative variables may be better representations. Fuzzy Set Theory is suggested as one approach to tackle the computation of such variables. The Neural Network Approach has a unique ability which, it is claimed, can capture unseen or hidden relationship among the spatial interaction data. A new method, called here the Fuzzy‐Neuro approach, is proposed for modelling travel demand with the expectation that it can improve the accuracy of the resulting models.

Rangeland condition, herder livelihoods and land tenure in the Gobi Desert

Rangeland condition, herder livelihoods and land tenure in the Gobi Desert Abstract: There is some evidence that privatisation of Gobi rangelands in Inner Mongolia (China) has caused land degradation. Rangelands have not yet been privatised across the border in Mongolia’s Dundgobi and Omnogobi provinces, but the current open access land tenure model is not without social and rangeland condition limitations. I will compare rangeland condition and forage availability under three different land tenure models within the Gobi Desert. This will assess the potential impact of changes in property rights on rangeland and livelihood sustainability. I will also collect socioeconomic information for each of the three 'treatments', thereby approximating herd dynamics required for herder family to be economically viable. Comparisons between the three ‘treatments’ will then identify the individual characteristics, and overall best land tenure model, for economically and environmentally sustainable grazing in the Gobi.

Linking macro level strategic transport forecasting models and traffic microsimulation models

Linking macro level strategic transport forecasting models and traffic microsimulation models

Abstract: Transport modelling can assist in decision making on all levels of transport planning from regional areas to individual road network element design. Costs of model development, maintenance and application would be significantly reduced if data can be exchanged consistently between different modelling levels. Very often the modelling output from one level of analysis can be useful as an input to another level either as a model calibration indicator or simply as a pure input to the modelling process. Some examples of possible data exchange flow include transport network elements, OD matrices, zoning system, traffic signal data etc. This is not an easy task since they may employ different mathematical algorithms and may use different traffic attributes. Nonetheless, an opportunity exists for data exchange of at least some common attributes.

Climate variability and its impact on observed rainfall in Australia

Climate variability and its impact on observed rainfall in Australia Abstract: Rainfall characteristics at different temporal resolutions play a significant role in sustainable urban water management. In my PhD study I am identifying the temporal characteristics and variability of point rainfall measured in capital cities of Australia. Statistical moments, lag1 autocorrelation, the Buishand’s Q test for homogeneity, the Mann‐Kendall test for trend and wavelet analyses for temporal variability are carried out for rainfall intensities at resolutions of 0.1, 0.5, 1, 3, 6, 12 hours and for the monthly rainfall depths and proportion dry ratios. Series of rainfall intensities at different temporal scales and the monthly rainfall depths and proportion dry ratios are accumulated from the high resolution rainfall dataset provided by the Australian Bureau of Meteorology. For the Melbourne station, homogeneity of rainfall intensity was found to increase as the temporal scale increases. Both rainfall intensities and monthly rainfall depths were found to be serially correlated. The 2nd, 3rd and 4th statistical moments of rainfall intensities increased as the resolution increased. While no statistically significant trends were found using the Mann‐Kendall test, there were indications that trends are more likely as the temporal scale increases. Wavelet power spectra identified a dominant frequency scale (0.25 to 1 year) in the 3, 6 and 12 hour rainfall intensities that were periodically observed in a 5 to 10 year cyclic order. This phenomenon could be influenced by the inter‐annual variability of the El Niño Southern Oscillation

A success‐feedback based project selection process for Australian construction organisations

A successfeedback based project selection process for Australian construction organisations

Abstract: There is much literature concerning the importance of project success, its measures and the ways to define success either qualitatively or quantitatively. Project selection factors and also different project selection techniques are mentioned in a variety of studies. However, project success related studies and project selection related studies have been undertaken and discussed separately up to now. A thorough analysis of the literature shows clearly that a good project selection results in project success. The more logically a project is selected, the more chance it will have of reaching project success. In addition, it is beneficial to apply a success‐based feedback for the selected project in terms of the project selection factors’ importance once it has been undertaken. Applying this cyclical relationship will lead an established organisation to project selection maturity. This cyclical relationship will also help the organisation have a more effective project selection process which is able to satisfy all organisational needs. However, the main gap in the knowledge is that this mutual relationship has not been discussed in any academic literature so far and as a result, the application of this relationship has not been employed in real industrial projects.

Spatial statistical analysis of Martian north polar crescentic dunefield self organization

Spatial statistical analysis of Martian north polar crescentic dunefield self organization.

Abstract: Ordered neighbour analysis has shown that dune geography for high‐latitude dune fields on Mars is not a random process, but one that identifies with a geomorphic system that has evolved towards a pattern of uniformity across a variety of spatial scales. Findings support the following:

Firstly, the nearest neighbour R‐statistic, regardless of crescentic dune morphology, expresses the most significant degree of dispersion relative to the R‐statistic of all other higher ordered neighbours and is consistent between ergs.

Secondly, crescentic dunes, regardless of morphology, have a tendency towards increasing spatial randomness as the distance between neighbours increases (i.e. at higher order neighbours.

Thirdly, crescentic dunes comprising barchanoid morphology exhibit the highest R‐statistics where they occur in relation to interspersed domes, barchan, barchan‐seif, and short barchanoid ‘chains’ and is consistent between ergs. Dunefield margins, where morphological diversity is greatest, exhibits the lowest R‐statistics relative to dispersion and tend towards random organization.

An investigation into the reuse potential of stormwater harvested and stored in permeable pavements

An investigation into the reuse potential of stormwater harvested and stored in permeable pavements

Abstract:

Pavements account for a large portion of the impervious area of urban catchments and are significant contributors to urban stormwater runoff. Permeable pavements are an established Water Sensitive Urban Design technology that can be used to detain or retain stormwater runoff on site. Permeable pavements have also been identified as a potential water harvesting mechanism. One way to implement stormwater harvesting and reuse using permeable pavements is by placing an impermeable liner around the structurally supportive base course media of the device.

There is little literature identified that addresses the impact of gravel media on microbiological contaminants. Since these contaminants are a significant concern for any aspect of water use, experiments were undertaken using the faecal indicator contaminant E. coli. The experiments aimed (a) to determine whether the E.coli will undergo growth or die off in a reservoir model (b) to compare the rate with which growth/decay of E. coli may occur in aggregate media, compared to a standard water storage (c) to determine if there is a significant effect on E.coli concentration by sampling at different heights of the storage reservoir.

Risk management associated with the construction of nuclear power plants in Australia

Risk management associated with the construction of nuclear power plants in Australia

Abstract: Australia faces increasing population growth. As well Australia needs more electricity generation, to decrease greenhouse gas emissions, to secure the supply of energy and to reduce dependence on energy imports. Consequently, Australia requires diverse strategies to solve these challenges. The construction of a nuclear power plant could be one of the diverse strategies employed. However, a nuclear power plant may risks such as: security, safety, the risk of nuclear proliferation, financial risks and nuclear waste. This research focuses on the project management use of a new risk management methodology that can decrease, mitigate and manage possible risks. The research uses case studies and interview surveys. Project managers who work in the nuclear industry, organizations that are responsible for security and safety at nuclear power plant, academics who support and academics who oppose building a nuclear power plant in Australia, will be interviewed for the research. The objective of the case studies and interviews are to validate and test the new risk management methodology. The findings and results of the research will be notified to the Australian National Nuclear Research and Development Organization (ANSTO), and the University of South of Australia.

Fate and dynamics of Endocrine Disrupting Chemicals (EDCRs) and Pharmaceutically Active Compounds (PhACs) in the soil environment.

Abstract: Humans and other animals produce biological wastes that can contain bio‐active chemicals derived from normal metabolic processes and from the ingestion of pharmaceutical formulations in medical treatments and in veterinary practices. Indeed, over 90 % of ingested pharmaceuticals are often excreted as the parent compound and/or as metabolites. Such biological waste material, derived from sewage treatment works and from intensive farming practices, are applied to nutrient‐impoverished agricultural land in cereal crop production. The focus of my studies is the possible negative impact of these bio‐active chemicals on the soil and adjacent environments. We have studied two groups of bio‐active chemicals: Endocrine Disrupting Chemicals (EDCRs) and Fluoroquinolone antibiotics.

Development of coagulation technology for optimised removal of environmental pollutants

Abstract: Climate change and extended drought periods have caused major negative impacts on water resources in Australia. The reduction of available water resources due to drier conditions in many parts of Australia is a critically important issue and developing improved and new ways of managing water resources for a sustainable future has become the national priority. Water quality degradation from environmental nano‐pollutants, dissolved organic matter and blue‐green algae (cyanobacteria) has increased in recent years as a result of greater human impacts on available water resources. To address these issues of major importance, greater research efforts are needed to secure water supplies of acceptable quality. The use of recycled water is one of a range of options available to better secure water resources and there are several technologies available for the treatment of wastewaters for fit‐for‐purpose reuse. However, there is a need to improve the cost effectiveness of treatment processes for the removal of the above contaminants and to expand the recycling of wastewaters.

Soil moisture patterns and ground movements on extremely reactive soils in the urban environment of South Australia.

Abstract: The thesis investigates the influence of immature Australian native and exotic urban street trees on soil moisture, ground movements, soil salinity, and ultimately house movements. Species’ water demands were assessed on extremely reactive soils in an urban environment. The extensive soil and tree monitoring program was based in a newly established subdivision in the northern suburbs Adelaide, South Australia. Although the potential influence of the immature street trees with time was not expected to be revealed directly, it was expected that projections could be made on future patterns of soil drying and associated ground movement from the preliminary data gathered during the life of the project. This research project is therefore regarded as somewhat foundational research in its long term goals, to investigate early trends arising from the construction of an urban subdivision.

Eeducation : a study of telecommuting potential in higher education institutions in Malaysia.

Abstract: The proposed study aims to explore the potential of telecommuting to reduce the need for physical travel by car, the vehicle kilometres travelled (VKT) and thus to reduce traffic congestion. This study will be focusing on academics’ travel behaviour and will examine the extent to which e‐education can reduce academics’ travel needs through telecommunication. The results of this study will contribute to our understanding of telecommuting generally and to the future planning of higher education institutions as well as contributing to future planning of KLMA. Teleworking in particular and telecommuting in general have been promoted as a means to reduce air pollution and traffic congestion. However, Bailey and Kurland (2002) argue that interruptions at traditional workplace (for example long, interrupted, noisy periods of work) are the driving factors which have led to telework. Travel demand modelling from the perspective of virtual accessibility is a key focus of this study.

Development of an environmentally friendly permeable concrete pavement material with enhanced structural strength

Development of an environmentally friendly permeable concrete pavement material with enhanced structural strength

Abstract: Permeable pavement is termed as comprising materials that facilitate stormwater infiltration and transfer to the underlying subsoil. It can be adopted as an alternative to traditional impervious hard pavements to control stormwater in an economical way. Permeable concrete is a subset of the broader family of pervious pavements, with by far the biggest use in landscaping, car parks and pedestrian areas. As it has been generally accepted that there is an inverse correlation between the volume of pores and the levels of stress to which the concrete can be subjected, permeable concrete has lower compressive strength capabilities than conventional concrete. This project aims to obtain a thorough understanding of permeable concrete and therefore to develop a concrete pavement material with adequate strength and permeability.

The Development of Railway level Safety Assessment model using Petrinet’s approach

Abstract: Even though the conventional approach has proven some solutions in reducing accidents at RLC, the fatality rate is still continuing to be the greatest concern in railway industry in Australia. The aim of the research is to develop a safety assessment model. An improved method is proposed using data from South Australia’s as a testing case. The development of a RLC safety assessment model will apply Stochastic Petri Nets to assess the performance and reliability of RLC location. The model will include related elements in RLC systems such as signal control, train and traffic characteristics. To understand the factors contribute to the failures at RLCs, the components such as engineering infrastructure, level crossing surrounding, human factors and nearby land use will be examined. With the improved methods using Stochastic Petri Nets, it is believed that the model can help in selecting sound alternative in prioritising locations for improvements or upgrade. The application of GIS in spatial representation of RLC locations will link model output with visualisation of the surrounding land use environment, and further enhance the understanding of RLC accident phenomena.

Benthic Foraminifera assemblages in the northern Spencer Gulf, South Australia ‐ further evidence for Holocene sea‐level changes.

Benthic Foraminifera assemblages in the northern Spencer Gulf, South Australia further evidence for Holocene sealevel changes.

Abstract: Spencer Gulf is an elongate, shallow marine embayment on the southeastern coastline of South Australia. In situ bioclastic sedimentation occurs within extensive seagrass meadows and mangrove woodlands. Vibrocore SG279, taken from 8‐10m water depth in northern Spencer Gulf, comprises 4m of Quaternary sediments. The uppermost 110cm is of Holocene age and mollusc shells at 98‐105cm yielded a radiocarbon age of 6,880 ± 85 yr cal BP. The species of foraminifera preserved as fossils in this core are extant in modern gulf waters and their environmental distributions are known. Nubecularia lucifuga, Peneroplis planatus and Vertebralina striata commonly inhabit shallow, subtidal to intertidal, seagrass meadows. By comparison, Massilina milletti is more abundant in deeper open gulf waters. In core SG279, the combined decreasing number of the three shallow water species upcore is interpreted as a proxy for water deepening, i.e. marine transgression. In contrast, Massilina milletti increases in abundance upcore, thus providing further evidence of marine transgression. Together, these four species record the Holocene postglacial marine transgression and its culmination is signified by the sediments at a core depth of 40cm. Declining numbers of Massilina milletti above 40cm signify subsequent marine regression which has been attributed to both hydroisostatic and eustatic processes.

The future of Project Procurement (PP) used in the Hong Kong consumer electronics industry

Abstract: The future of the Hong Kong consumer electronics (CE) industry is full of uncertainties because it is facing many new challenges coming from mainland China and worldwide such as ongoing Chinese regulatory system changes, rising labour costs, stricter environmental protection requirements and growing protectionist sentiment in the U.S. and European Union, (Wong, 2007). According to the researcher observation, many companies have already shut down while some others companies are struggling to survive. There are very limited studies on the PP in CE industry in comparison with the construction industry as most emphasis is placed on construction projects (Dawson, 2004). This research intends to fill the gap by means of a comprehensive study of the PP methods. It is imperative to investigate to what extent the PP methods can impact the project success and the future trend of procurement strategy in the Hong Kong CE industry.

Construction managers and quality management in Hong Kong building projects

Abstract: Quality management has been implemented in Hong Kong construction for more than 10 years. However a numbers of literatures revealed that performance of construction still did not have significant improvement. The theory of quality management emphasizes the importance of total participation of various stakeholders to quality. This study aims to explore what management dimensions such as leadership, communication and training, and their combined effect could enhance contractor participation on construction quality. An explanatory model will be developed to describe how the three quality dimensions, leadership, training and communication can be integrated together to achieve the desired level of participation from construction managers in implementing a QM programme.
