在适当控制清水冲刷强度、避免宽河段河势发生较大变化的前提下 ,从有利于下游尤其是艾山以下河道的减淤、恢复主槽行洪能力、改善当前下游河道不利的防洪局面出发 ,论证了小浪底水库起始运行水位淤满前的运用方式。推荐起始运行水位采用 2 10m ,2 0 0 0年采用 2 0 5m。调控上限流量采用 2 60 0m3 /s ,调控库容采用 8亿m3 。
On the premise of properly controlling the scouring intensity of clean water and avoiding large changes in the river regime in the broad reach, the flood control capability of the main channel will be restored from the benefit of the de-siltation in the lower reaches, especially in the lower reaches of the Ai Mountain, so as to improve the adverse flood control situation in the lower reaches of the current river Departure, demonstrate the Xiaolangdi reservoir starting operation before the water level silting the way. The recommended initial operating water level is 2 10m and 2000 is 205m. Regulate the upper limit of flow with 2 60 0m3 / s, control storage capacity of 800 million m3.
