Abstract:
... Hydropower plant (HPP) operation may influence downstream flow regimes, which can affect the fish movement. In South America, tailrace fisheries are often killed or injured when interacting with spillways and turbines. Hydrodynamic flow-pattern studies are essential to facilitate mitigation. We developed a computational fluid dynamics model to investigate flow downstream of Três Marias HPP (Brazil ...
