本文通过对泾河来水来沙特性及渭河下游冲淤规律分析，提出东庄水库“常年蓄清用浑，汛期合理畅泄，河库联合调度，多年冲淤平衡”的运用方式。同时．论证分析了该方式运用后不仅可使水库保持较大的长期有效库容，而且能有效地减轻渭河下游淤积并控制潼关高程上升。 Based on the characteristics of incoming and outgoing water from the Jinghe River and the scouring and silting laws in the lower Weihe River, this paper puts forward the application of the “application of muddy water for years, rational drainage in the flood season, combined regulation of the river bank and scouring and silting balance for many years in the Dongzhuang Reservoir”. Simultaneously. The demonstration analyzes that the method can not only maintain a large long-term effective reservoir, but also effectively reduce the siltation in the lower Weihe River and control the elevation of Tongguan.
