INNOVATION IN GEOSCIENCEWET AREA MAPPING
PROVISION OF FOUR PLANNING TOOLS
FLOOD: delineating likely extent of flood extent, depending on flooding type (coastal, riverine, streams, depressions), with an without hydrological infrastructure intact.
LOCATE: tool to rank hydrological infrastructure (culvert, bridges, storm water systems) by capacity to accommodate expected, weather-dependent flow rates .
TRAIL: optimizing trail and road routing tool and lineal projects
SPILL: tracking likely path of water-borne contaminants from spill source
KNOWLEDGE BASEFURTHERING ECONOMIC ACTIVITIES
How can we manage the challenge of uncertainty (future flood scenarios, precautionary principle)?
• Using maps layers that locate flood vulnerabilities within specific community and property contexts
• Systematically locate, quantify and risk-prioritize flow blockages:• depressions, • eroding slopes and stream channels, • flow blockages (roads, dams, dykes, culverts, bridges, stream and river narrows)• systematic mapping of the changing permafrost conditions
• Reduce flow rates through • trail and road decommissioning • restrict developments in floodplains, wetlands and depression• soil protection• stretch snowmelt season through watershed-based management of forest / vegetation cover
Improve flood forecasting and mapping through systematic GPS-GIS capture and analysis of flood events and damage reports; includes integration of river watch programs and activities
Mapping inland to coastal flooding: streams, rivers, lakes
Findings appropriate for utilization on delineating corridors within Permafrost Zone
ForHyM enables the modelling of soil moisture and freeze thaw cycles within the Fort Simpson area, and elsewhere.
The cartographic DEM-based depth-to-water modelling protocol enables a systematicmapping of the upland-wetland distribution.
This modelling would also enable a systematic mapping of the changing permafrost conditions.

Hydrological risk mapping deals with locating and delineating areas where there would be potential risks in terms of flooding, wash-out, erosion, mudslides and avalanches. Planners working with industry, municipalities and developers are aware of these risks but do require good mapping tools that reveal these risks in a fairly reliable fashion and in sufficient detail.
Hydro-Risk Mapping
The corresponding depth-to-water wet- areas maps, associated with each of these channel networks, showing where water would, cartographically, be within 1 m from the soil surface nextto each flow channel, lake, and shore line.
The areas that would potentially flood when all culverts and bridges are plugged, and when they are not plugged.
The areas that would flood when the water level along the main flow channels rises to and beyond historical levels.

MINING AND CLIMATE CHANGE
Climate VulnerabilityCLIMATE CHANGE IMMUNIZATION
• Infrastructure Protection
• Relocation
• Flood mitigation
• Responding to emergencies
• Business continuity plans
SYNERGY BETWEEN ADAPTATION & MITIGATION
• Preservation of hydrological surface currents
• Mitigation of hydrological extremes
• Retention of soils and sediments
• Support productivity and biodiversity
• Maintenance and purification of water resources
• Adaptation policies, plans and practices
• Designing flood defenses and flood storage
• Design additional roads in flood situation
• Improve drainage
It requires a study of climate vulnerability. Thus produce climate immunization through:
WATER CONSERVATION
CLIMATE CHANGE AND CANADIAN
MININGNORTHERN CANADA:• In the winter, the region of Hudson
Bay and the southern portion of the Foxe Basin are projected to see the largest winter temperature increases of any region in Canada.
• In the summer, the temperatures in the Foxe Basin and Hudson Bay regions are projected to increase less than the rest of Northern Canada.
• Precipitation will generally increase across Northern Canada, more so in the winter and increasing over time.
