The model is used for the assessment of ecological integrity of rivers by providing quantitative information of habitat qualities for fish, benthic invertebrates and macrophytes. Different scenarios concerning flow rates and regimes as well as structural modifications can be simulated to find optimum management strategies. Within the modelling procedure a fuzzy-rule based approach gives the opportunity to integrate linguistic expressions and expert knowledge about fish behaviour and habitat demands. Examples of the model application to minimum flow regulation and river restoration are given.Text/Conference Paper
