永定新河河口水文特征分析

Study on the hydrological characteristics of the mouth of Yongdingxinhe River

为研究永定新河河口水文情势,采用一维恒定非均匀流方法计算各种组合工况下河道的水位、流速等要素,进一步分析了下边界潮位、河道计算工况对永定新河河口洪水位、流速的影响。该成果可为永定新河河口的工程设计和防洪评价提供参考。

To study the hydrological situation of the mouth of Yongdingxinhe River,the water lines and velocity were calculated from the one dimensional model. Influence of downstream tide and river conditions on the flood level, velocity were analyzed. The results could provide a reference for engineering design and flood control evaluation of the mouth of Yongdingxinhe River.
