The result shows that it is resultful to decrease the sediment depositing to the reservoir area when reducing the water level at the same incoming water and incoming sediment. 计算结果表明在同等水沙条件下，降低库水位对于减少库区泥沙淤积是有利的。
In a word, it is necessary to use the hydrodynamic model to give the water levels at any sites when compiling the bathymetrical data for accurate results. 黄河口治理的出路是，在于控制适当的入海水沙条件和用较大的容沙体积换取较长的行河时间。
