Abstract: Computer models for quantifying impacts of river regulation on fish habitat have been applied to several projects in Norway. The existing models are all based on one-dimensional hydraulics and habitat criteria based on observed habitat use and availability. Developments and the easy access to inexpensive high performance computers have lead to increased use of'two or three-dimensional hydraulic models, giving new possibilities for habitat assessment studies. Developments in biological modelling also lead to a need for new and more flexible models. This paper describes the results of a project that has the goal of providing a model that incorporates the latest developments while being expandable for future additions as new methods are developed. To achieve this, the development was based on an object-oriented development strategy that used a general framework for habitat modelling. The paper describes the development strategy and the available hydraulic and biological modelling options. Some of the applications of the model components are also described.
