摘　　要：依据永定新河河道多年的冲淤形态和潮汐水流、泥沙的特征,对永定新河的冲淤规律进行了分析,提出了海河流域淤泥质河口在以潮流为主要动力条件下,感潮河道的冲淤规律,揭示了淤泥质河口在潮流动力作用下的演变过程,对类似河道及河口治理具有借鉴作用。In accordance with the annual silting pattern,the tide water flow and the characteristic of sedimentation in the river course of Yongdingxinhe River,the analyse is done for the silting regulation of Yongdingxinhe river.The silting regulation of tidial waterway under the the condition that the tidial flow is the main dynamic in the argillaceous river mouth of Hehe river basin is also put forward.The evolution process of silt river mouth under the action of tital dynamic is also brought to light and it will play a role of refererce to the improvement of similar river course and river mouth.
