River damming has brought great benefits to flood mitigation, energy and food production,
and will continue to play a significant role in global energy supply, particularly in Asia, Africa …

Fish migration is essential to maintain healthy aquatic ecosystems, but hydraulic structures
across rivers have impeded natural fish migration worldwide. While efforts have been made …

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 …

Turbulent flows are investigated upstream of a bar rack system that is recommended as
optimum in recent literature from tests with several fish species of different morphology …

Atlantic salmon (Salmo salar), brown trout (Salmo trutta), and steelhead trout (Oncorhynchus
mykiss) kelts have important conservation value for population resilience. Nonetheless …

Preventing fish entrainment during their downstream passage at hydropower plants remains
a major challenge in reducing the ecological impacts of hydropower production. We …

Fish protection screens are being increasingly applied to prevent fish entrainment at water
diversions and intakes. Screen success is thought to depend upon selecting the most …

Hydropower plants act as a barrier to fish moving in rivers. Fish guidance structures like
angled bar racks with horizontal or vertical bars are used to protect downstream moving fish …

Anthropogenic structures often block or delay the downstream migration of fish in rivers,
thereby affecting their populations. A potential solution at run-of-river hydropower plants …

Desanding facilities (DFs) limit particle sizes and reduce the suspended sediment load in
hydropower plants. Multiple successive tranquilizing racks (TRs) at settling chamber inlets …
