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."
