小浪底枢纽进水塔上游形成高滩深槽的过程

Formation of High Floodplain and Deep-cut Channel Upstream of the Xiaolangdi Intake Towers

小浪底枢纽进入正常运用阶段后，库水位将在２３０～２５４ｍ之间变动，随着蓄水位的升降，进水塔上游将形成高滩深槽的河床形态。文中根据１：８０正态泥沙模型对１９５０～１９７０年共２１个水沙系列年进行了模拟试验，对高滩深槽的形成过程及有关泥沙问题进行了分析和预报。

During the normal operation period of the Xiaolangdi Reservoir,the water level will fluctuatebetween 254 and 300m:The configuration of the river bed upstream of the intake towers will take theshape of high floodland and deep-cut channel as the water level fluctuates. The paper describes thesimulation, using the 1: 80 sediment model, of 21 water-sediment series from 1950-1970. Also, itanalyzes and predicts such formation and related sediment problems.
