| 摘 要： | 根据小浪底水库2002~2015年的调水调沙资料,对泺口至利津河段的冲淤情况进行分析,认为调水调沙使泺口至利津河段的河道得到明显冲刷,主槽断面形态向良性发展,平滩流量大幅增加,过流能力大大增加。同时近几年调水调沙资料表明河道冲刷力度减弱,冲刷效率降低,河床粗化,主槽过流能力已基本稳定。

| Abstract: | According Xiaolangdi Reservoir 2002~2015 years of water and sediment regulation data,situation of erosion and siltation of watercourse of Luokou to Lijin was analyzed, that water and sediment regulation to make Luokou to Lijin river erosion significantly, the cross-sectional shape of the main channel to the sound development, bankfull discharge increased,flow capacity greatly enhanced,but in recent years, sediment regulation data show that river erosion weakened, erosion efficiency reduced,riverbed coarsening,the main channel flow capacity has been basically stable. |

| Keywords: | water and sediment regulation erosion and siltation flow capacity |
