鉴于瀑布沟水库是大渡河流域梯级开发中游控制性水库，控制了大渡河88．5％的集水面积和83．3％的泥沙量，为掌握水库投运后对下游河道径流和泥沙造成的影响，特依据下游沙坪水文站径流、泥沙资料进行分析，成果表明：瀑布沟水库的投运调节了下游水库径流分配，使得下游水库年内径流量分布更加均匀，大大降低了下游水库的含沙量和输沙量，有效改善了大渡河下游电站泥沙问题。
鑒于瀑佈溝水庫是大渡河流域梯級開髮中遊控製性水庫，控製瞭大渡河88．5％的集水麵積和83．3％的泥沙量，為掌握水庫投運後對下遊河道徑流和泥沙造成的影響，特依據下遊沙坪水文站徑流、泥沙資料進行分析，成果錶明：瀑佈溝水庫的投運調節瞭下遊水庫徑流分配，使得下遊水庫年內徑流量分佈更加均勻，大大降低瞭下遊水庫的含沙量和輸沙量，有效改善瞭大渡河下遊電站泥沙問題。

Pubugou Hydropower Station , a controlling reservoir in the middle reaches of Dadu River basin cascade de-velopment, controls 88.5%of the Dadu River catchment area and 83.3%of sediment.In order to grasp the impact on downstream river runoff and sediment after station puts into operation , the hydrological test results obtained by down-stream Shaping Hydrological Station are analyzed .The results show that the reservoir can regulate the flow distribution of downstream reservoirs , makes yearly runoff more even , greatly decreases the sediment concentration and sediment dis-charge, and effectively reduce the sediment of the Dadu river downstream hydropower stations .
