Description
Abstract:
Besides passability the attraction of a fishway at the tailwater of a barrier with a hydropower plant is the most important criteria to ensure that a fishway is fully functional. The relevant national and international guidelines and regulations give recommendations regarding the position of the entrance or multiple entrances, the entrance geometry, the substrate connection and the attraction flow. Fishways currently planned at federal waterways in Germany, as well as existing structures have various types of entrance arrangements. Mainly three different types can be found that differ significantly in the entrance configuration but comply with the recommendations regarding attraction given by the current guidelines and regulations. To asses and compare the three different entrance configurations at several relevant hydraulic boundary conditions physical model tests in a 1:10 scale model of a barrier with a hydropower plant were performed. The resulting flow conditions in the tailwater were measured in detail with a 3D ADV probe, related to the behavior and swimming abilities of the relevant fish species and evaluated regarding the formation of a suitable migratory corridor with a significant attraction flow.

Comments
Presenting Author Bio: Wolfgang Kampke is a Civil Engineer with the Federal Waterways Engineering and Research Institute of Germany. After graduating from the University of Karlsruhe in 2002, he worked as research associate at the Institute of Water and River Basin Management of the Karlsruhe Institute of Technology (KIT). Wolfgang’s work experience includes fundamental and applied research on river restoration, fish passage design, fish behavioral monitoring, physical modeling and hydropower. He is a doctoral candidate at the Karlsruhe Institute of Technology under the supervision of Prof. Franz Nestmann, KIT and Prof. Peter Goodwin, University of Idaho and his doctoral research focuses on flow parameters, with turbulence in particular, and their influence on the swimming behavior of fish. In 2011 he joined the Federal Waterways Engineering and Research Institute where he is consulting the Federal Water and Shipping Administration in designing fish migration structures. He is also involved in setting up a multi-disciplinary research program on ecological connectivity and fish migration at Federal Waterways.
