In a period of time, the fluvial processes are getting active, which increases the movement of sediment and results in unfavorable effect on the maintenance of the channel. 一段时期内，河床演变趋于活跃，增加了泥沙活动，对航道维护有不利影响。
Using the basic theory of soil moving and river bed changing,the authors made rush-siltation balance analysis and calculation and put forward dredge-harnessing scheme. 整治方案运用了泥沙运动的基本理论和河床演变的基本原理，对马尾河进行冲淤平衡分析计算，并按水动力学规律疏浚整治河道，以恢复河道良好的水力条件，稳定河势。
