梯级水电站对库区和河道水温的影响预测
Influence forecast of the cascade power stations on water temperature of reservoirs and rivers
摘要
Abstract
The one-dimensional and three-dimensional hydrodynamic and water temperature numerical models for a reservoir of the cascade hydropower station with different temperature types were established to study the influences of the cascade hydropower station construction on the water temperature.The results show that after the construction of the stations,the vertical distribution of water temperature in the reservoir changes; the difference between the bottom and surface water temperatures increases ; the spatial and temporal distributions of water temperature in the lower reaches of the river change ; the variation range of water temperature in the lower reaches of the river decreases ; and the annual average water temperature of the discharged flow decreases.关键词
