Study on Scheme of Replacing Desilting Basin with Reservoirs for Daily Regulating Power Stations in Sediment-Laden River
The river where a hydropower station is located in Nepal is a typical river with high sediment concentration.The power station is a peak-shaving runoff(PRoR)high-head power station,and sand prevention and sediment discharge are particularly important.The authors studied the feasibility and economy of the replacing desilting basin with reservoirs scheme,combined with the numerical analysis results of hydrological and sediment operation,adopted a more reasonable flushing and desilting design and anti erosion measures for the unit to save engineering investment.This study can provide reference for other similar engineering design.
