当拦水坝修成以后水库便开始逐渐充水,对于大型水库说来要使水位涨至设计标高,必须经过很长时间,充水期往往延长至数月乃至几年。充水后在水库经营期间,水库中水位还将按一定动态而变化。例春季水库逐渐充满水,以后却逐渐放水用以发电、灌溉等,水位遂逐渐下降。而我们知道,潛水迴水量除与地质、水文地质条件有关以外,尚紧密地和水文条件相联系,水文条件在
When the dam is completed, the reservoir begins to be gradually filled with water. For large reservoirs, it is necessary to make the water level rise to the design elevation. After a long time, the water-filling period usually extends to several months or even years. After filling the reservoir during operation, the water level in the reservoir will also change according to a certain dynamic. In the spring, for example, reservoirs are gradually filled with water, but later they are gradually released into the water for electricity generation and irrigation. The water level gradually decreases. However, we know that, except for the geologic and hydrogeological conditions, the return of submersible water is still closely linked with the hydrological conditions at
