Ecologic Institute 2021: Inclination directions and approach flow angles of fish protection screens relevant for guiding function. Infographic published in: Wagner, Falko 2021: What makes a screen to a fish protection screen? The functional components of a fish protection system. Jena: Institute of Aquatic Ecology and Fish Biology, IGF Jena.
This infographic shows the differences between horizontally angled and vertically angled fish protection screens. Fish protection screens with vertical angular flow have a guiding effect towards the surface and guide the fish to the bypass close to the surface. Fish protection screens with horizontal angular flow have a lateral guiding effect towards the bypass. The approach flow angles of the screens have a decisive influence on their guiding function (horizontal approach flow angle θ, vertical approach flow angle α). The infographic is part of the fact sheet "What makes a screen to a fish protection screen? The functional components of a fish protection system."
