黄河口人海流路规划中泥沙数学模型的应用

Appliaction of Sedimentation Models for Planning the Course of Yellow Ricver on the Estuary

在黄河口入海流路规划中,曾用不同的泥沙数学模型对河口水位变化和入海流路的行河年限进行计算,在各模型关于清水沟流路行河年限计算成果比较中可见,由于计算条件相同,成果的差异不大。此外,作者根据神仙沟和钓口河实测资料,分别推估一定防洪水位下的行河年限,结果与各模型计算值相近。总之,应用泥沙数学模型预估入海流路行河年限作为规划依据是可信的。

In the planning of the course of Yellow River on the estuary, different sedimentation models were used for calculating the water level in the course and operating age of the courses to sea. Gomparison of operating ages for Qingshuigou course calculated by the models shows that these models gave simular results under simular calculating conditions. Besides, the author estimated respectively operating ages of Shengxiangou and Diaokouhe courses, and got the results close to the values calculated by the models. In other words, operating age of course to sea calculated by the models is believable as the base for course planning.
