三峡水库不同调度方式对荆江三口分流影响分析
Influence of different operation modes of Three Gorges Reservoir on division of three channels of Jinjiang River
摘要
Abstract
To understand the influence of different operation modes of Three Gorges Reservoir on division of three channels of Jinjiang River, the reduction calculation of natural runoff of daily average discharge of the controlling station of three channels of Jinjiang River under small-medium flood operation mode(from 2010 to 2013) was conducted, by using daily inflow of Three Gorges Reservoir, daily discharge of Yichang Station and 5 stations of three channels from 1998 to 2002 before the impoundment of Three Gorges Reservoir. The daily average discharge of the controlling station of three channels under the initial designed oper-ation mode of Three Gorges Reservoir is simulated and calculated and the influence of the initial mode and the current mode on division of three channels of Jinjiang River is analyzed. The optimal operation mode of Three Gorges Reservoir is discussed on the basis of the analysis results and by consideration of the seasonal water usage demand of three channels. It is proposed that the im-poundment of Three Gorges Reservoir should be advanced to 1st, September, so as to reduce the zero-flow days of three chan-nels.关键词
