| 摘 要： | 针对三峡水库蓄水以来输沙量与地形法计算所得枝城～城陵矶河段冲刷量相差太大,导致实测资料很难使用的问题,利用蓄水前的实测数据建立了枝城～城陵矶河段水位变化值与该河段冲淤量的相关关系,并类比分析了2003-2007年期间两种方法测量成果。如果以水位下降值来判断该河段冲刷量,则输沙量法的成果更为合理。

| Abstract: | As calculations of the erosion volume in the Zhicheng-Chenglingji reach influenced by operation of the Three Gorges reservoir by the sediment-transport balance method and the topographic method based on the measured data are much different,how to use these measured data of this reach becomes a difficult issue.To solve this problem,this paper establishes a correlation relationship between the water level variation and erosion-deposition volume measured before operation of the reservoir,and analyzes the diffe... |
