Abstract

Whereas upstream fish migration facilities are rather well established, there remains a lack of efficient downstream fish migration facilities. Following the main flow most fish pass through the turbines which results in major damages and mortality rates. The main challenges of downstream fish migration are to prevent fish from passing through the turbines and furthermore enable them to find the entrance of the downstream passage. A conceptual solution was investigated in the laboratory of Hydraulic and Water Resources Engineering of Technische Universität München. A life size experiment with potamodromous species was conducted to study the fish behaviour at the intake of a hydraulic structure. In a large open air lab flume the possibilities to shield the fish from crossing through a screen and lead them to a surface bypass with an inclined trash rack was examined. Different trash rack inclinations and bypass designs were tested.
