Abstract
In the DBU-sponsored project “MeMo Downstream Fish Migration” the improvement of the downstream passability of our river system is the overall objective. Until today, a state of the art hasn’t been defined for downstream migration facilities and it is not known by which specific factors fish may be influenced. To address these aspects, the following central elements are processed in the project:
- a bioinspired measurement system, which can record multiparameter data in a similar manner as a fish senses the flow and
- a CFD-based modelling system, which can be applied to forecast fish behaviour as a function of simulated flow parameters.
Various transdisciplinary research methods are used for this purpose: from observation of living fish in a flume in the hydraulic laboratory at TU Darmstadt and flow measurements with various measuring systems in the laboratory as well as in the field to hydrodynamic-numerical simulations.
