近年来，渭河高含沙小洪水出现频繁，对潼关高程十分不利，2002年6月潼关高程曾一度升高达到329.14m，为有史以来最高值。

In recent years , small discharge floods of hyper-concentration sediment from Weihe River occurred frequently and had negative influences on Tongguan Elevation rising to 329.14m in June 2002 that is highest one in history .

汛期多水少沙的洪水过程是2003年潼关高程冲刷下降的主要原因，过渡方案控制非汛期最高水位不超过318m的作用不大。

The decrease of the elevation of Tongguan station in 2003 was mainly caused by the flood flows in the flood season , while the interim scheme of limiting the pool level not exceeding 318m had a little effect .

所以降低三门峡水库的运行水位，可为潼关高程的降低创造必要的条件。

Lowering operational water level of the Sanmenxia Reservoir will provide the necessary condition for the lowering of the stages at Tongguan .

结果表明，潼关高程与渭河下游泥沙冲淤密切相关，潼关高程下降后，渭河会产生溯源冲刷。

It may infer that if Tongguan 's elevation is descended by2m , the gradient of lower reaches of Weihe River will increase because of retrogressive erosion .
