Short description
At the hydropower plant Glüder (Wupper – near Solingen close to the gauge Glüder) a monitoring of the fish migration is carried out by using HDX-technology and transmittered fish. In order to be able to better interpret the knowledge gained on the migration paths and whereabouts of the transmittered fish, it is necessary to have knowledge of flow signatures. By intersecting the fish movements and locations with the currents, the preferred swimming paths, dwell and avoidance areas as well as the detectability of existing facilities (e.g. the fish ladder) are to be ethohydraulically justified. Building on this basis, it should then be possible to plan and implement sustainable measures for fish protection as well as for fish ascent and descent in the course of plant renovation.
The Chair of Hydraulic Engineering was commissioned by the Düsseldorf district government to carry out hydrometric measurements at the Glüder hydropower plant to record the flow directions and flow velocities. Based on this, a three-dimensional flow model of the entire plant was to be set up, calibrated and used to predict the flow signatures during special discharges and operating conditions.
