In this paper the mathematical modelling of the distribution of average velocity along the vertical in alluvial rivers has been studied According to the data measured from natural rivers,a formula for computing the roughness distribution across the river channel is obtained. Based on the basic idea of the stream network method,a finite difference method is used for solving the equations of motion and a two-dimensional mathematical model is established. This model not only can avoid the arbitrariness in drawing the plane flow diagram of the stream network, but also can reduce the computing time and computer storage.The model has been verified by field measurments from two typical river reaches--a meandering reach at Yanguan and a straight reach at Damazhou in the Middle Yangtze River.

本文对冲积平原河道平面二维流速分布的数值模拟进行了研究。通过资料分析得到了综合糙率沿河宽的分布规律。基于绘制水流平面图的基本思想,用差分法求解水流运动方程式,建立了数学模型,避免了以往水流平面图法的任意性,又可减少一般差分法的计算量及贮存量,经长江中游河段的实测资料验证,符合良好。

Based on a large number of measuring data in the field, the development and formation of varied gravel shoals in Chuanjiang River are investigated in this paper. For example, the formative causes of gravel shoals at the mouth of rivulet, the gravel shoals in the middle of river and in the branched reach, the gravel bank shoals in the straight-wide reach and in the meandering reach are described. The investigations of formative causes are helpful to make regulation plans of the gravel shoals in Chuanjiang...
