影响潼关高程的主要因素有来水来沙条件、上下游河段冲淤状况和坝前运用水位，其中来水来沙条件起着主导作用。潼关高程的变化受下邻河段（黄淤３６～４１断面）冲淤的影响要大于上邻河段（黄淤４１～４５断面）。减少三门峡水库非汛期高水位的运用对减缓非汛期潼关高程的抬升起着重要作用。清淤河段选在黄淤３０断面以上，重点在黄淤３６～４１断面。清淤时间分为桃汛期和汛期两个时段。清淤对潼关高程的上升趋势起到了一定的抑制作用。
Affect the elevation of Tongguan main factors are incoming water and sand conditions, the upper and lower reaches of the scouring and dam status and the use of water level before the dam, in which water and sand play a leading role. The variation of Tongguan elevation is more affected by the scouring and silting in the lower reaches of the lower reaches (sections 36-41 of Yellow silt) than in the upper reaches of the upper reaches (sections 41-45 of Huang silt). Reducing the use of high water level in non-flood season of Sanmenxia Reservoir plays an important role in slowing the elevation of Tongguan elevation in non-flood season. Qing dredging river section selected in the yellow silt 30 section above, focusing on the yellow silt 36 ~ 41 section. Dredging time is divided into peach flood season and flood season two periods. Dredging on the rise of Tongguan elevation has played a certain inhibitory effect.
