(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 Habitat quality for benthic invertebrates  BHABIM Structural and hydraulic characteristics of rivers  SORAS High resolution fish habitat modelling (pref functions)  FHABIM 1997 Unsteady 1D-hydraulic modelling  AG1 Fuzzy-rule-based integration of fish habitat demands FHABIM 2 2000 Calculation of near bottom forces distribution  BHABIM 2 Vegetation in riparian and floodplain zones  VEGSIM CASIMIR (Computer Aided Simulation of Instream Flow Requirements)

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) fry juvenile spawning adult Habitat suitability grayling Hydro power station

Research and development Standardized method for the certification (approvement) of „green“ hydro power stations category 4: no fish Olivone category 3: no reproduction, fish individually stocked category 2: Upstream of first natural barrier reproduction possible Malvaglia category 1: Downstream of first natural barrier Biasca 5 km

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
