Analysis of Hydrological Regime Variation in Three Outlets of Jingjiang River after the Impoundment of Three Gorges Reservoir
摘要
Abstract
According to the storage operation time of Three Gorges Reservoir,the RVA method and the total degree of change are used to evaluate the variation degree of hydrological regime of three outlets in Jingjiang River.The results show that the operation of Three Gorges Reservoir has certain impacts on Jingjiang three hydrological regimes,and its hydrological comprehensive change degree is 62.07％.It is shown that the impacts include monthly average flow rate in January to May,July,August and October,annual average minimum flow rate of 1,3,7,30 and 90 d,and the valley bottom number and duration time of low flow.The operation of Three Gorges Reservoir has an obvious flood peak reducing effect on Jingjiang three outlets.关键词
