Abstract:
Mitigating the adverse ecological impacts on stream ecosystems caused by hydropower expansion is a major challenge. To prevent fish from turbine entrainment and to reduce injury and mortality risk, physical barriers such as fine screens with horizontally or vertically oriented bars are frequently installed at turbine inlets. In this study, the species- and size-dependent protection from turbine entrainment of different types of fish protection screens (FPSs) were investigated at five hydropower...     »
