高浓度调沙是减缓黄河下游河道淤积的有效途径

在浅析黄河下游河道淤积原因的基础上,指出高浓度调沙是减缓下游河道淤积的有效途径。为实现高浓度调沙,小浪底水库应该采用“蓄浑排清,清水刷槽;加沙造浓,高浓度输沙”的调水调沙方式,并通过“横向冲蚀”技术,来源源不断地形成高含沙水流出库。

An Effective Way for Slowing Down the Sedimentation in the Lower Yellow River Course through Hyper-sediment Concentration Transportation

The paper puts forward an effective way for slowing down the sedimentation in the lower Yellow R iver course through hyper-sediment concentration transportation based on simple analysis of sedimentation reasons in the lower Yellow River course. In order to achieve hyper-sediment concentration transportation, the Xiaolangdi Reservoir should adopt the operational mode of "storing muddy water and releasing the clear, scouring the channel by clear water, increasing sediment concentration through scouring and transport ing the flow with high sediment concentration" and the technology of "lateral erosion" to form a stream with high sediment concentration flowing out of the reservoir continuously.
