Changes of the Stage-Discharge Relation in Jingjiang River after the Impoundment of Three Gorges Reservoir

Abstract: 根据三峡工程蓄水前后的实测资料,分析了荆江河段沿程水位流量关系变化。研究成果表明:除枝城站在枯水流量下水位略有下降外,上荆江在中、枯流量下水位也均有一定程度的下降,其中沙市站枯水位下降最大,下荆江河段水位在同流量下略有下降。除枝城站枯水位变化受卢家河浅滩形成的沙坎石泓影响外,三峡工程蓄水后影响荆江河段水位流量关系变化的主要原因是:荆江河段处于冲刷状态,尤其冲刷主要集中在枯水河槽。
