CASIMIR
(Computer Aided Simulation of Instream Flow Requirements)
Main interests and development of CASIMIR
1990 Minimum flow in diverted river sections
1992 Energy production in hydro power stations WASKRA
1993 Habitat quality for benthic invertebrates BHABIM
1994 Structural and hydraulic characteristics of rivers SORAS
1996 High resolution fish habitat modelling (pref functions) FHABIM
1997 Unsteady 1D-hydraulic modelling AG1
1998 Fuzzy-rule-based integration of fish habitat demands FHABIM 2
2000 Calculation of near bottom forces distribution BHABIM 2
2001 Vegetation in riparian and floodplain zones VEGSIM
Modelling experience and practice
• Habitat investigations (PHABSIM, CASIMIR) in river reaches of different type and dimension (lowland to alpine region, 500 l/s to 300 m³/s)
• Flow regulations based on habitat modelling for numerous hydro power stations (ranging from 50 kW to 100 MW)

Research and development
•Standardized method for the certification (approvement) of „green“ hydro power stations
•Development of a user friendly software for ecological investigations on river systems, integration of fuzzy-approach
•Definition of preference functions and fuzzy-rules in cooperation with biologists
•Application and extension of CASIMIR for the efficiency prediction and control of mitigation measures in main channel...

• Contribution to the development of a System of Models for the Integrated Management of catchment areas
