小浪底水库移民安置区温孟滩河段河道整治模型试验研究结果表明，在水库拦沙运用期冲刷严重的初始河道地形条件下遭遇大洪水后，河势变化不大，河道整治工程对大洪水是基本适应的，但存在个别工程入流过死，局部冲深大和送溜不力等情况。由于前期河床已冲刷下切，河槽泄洪能力大大增加，洪峰期（Ｑ＝１００００ｍ３／ｓ）基本未出现明显漫滩。本文对局部冲刷的基本规律也作了探讨。
The result of the model test of Wenchuantan reach of Xiaolangdi Reservoir Resettlement Area showed that there was not much change in the river regime after the flood in the initial channel topography with serious erosion in the reservoir sediment recovery period. Basic adaptations, but there are individual projects into the death of excessive death, local Chong Shen deep and sent slip weak and so on. Due to the erosion of the riverbed in the early period, the flood discharge capacity of the river channel greatly increased. Flooding (Q = 10000m3 / s) showed no obvious floodplain. This article also discusses the basic rules of local scouring.
