金沙江下游梯级水库淤积及其对三峡水库影响研究
Sediment Deposition of Cascade Reservoirs in the Lower Jinsha Riverand Its Impact on Three Gorges Reservoir
摘要
Abstract
Xiangjiaba Reservoir and Xiluodu Reservoir have successively entered impoundment stage since 2012, and in the meantime intercepted sediment from the lower Jinsha River.According to field data of runoff, sediment and some cross-sections, the amount and distribution features of sediment deposition in the cascade reservoirs since their operation are calculated, and their influences on the Three Gorges Reservoir (TGR) are studied.Results indicate that sediment deposition in Xiluodu Reservoir and Xiangjiaba Reservoir are both less than the estimated amount.The cascade reservoirs reduced the incoming sediment of TGR, and correspondingly reduced the deposition in its tail reach.The research results are of great significance for the operation of cascade reservoirs and the regulation optimization of TGR.关键词
