现有的计算沉沙池泥沙沉降和出口水流含沙量方法存在着一些缺点。通过研究，取得了计算灌溉沉沙池的新的简单方法，可求出沉沙池出口含沙量和水力糙度平均值，将计算数值与原型观测和试验研究结果进行比较，证明此新方法有更高精度。
The existing methods for calculating sediment concentration in sediment basin and sediment concentration in outlet flow have some shortcomings. Through the research, a new and simple method for calculating the sediment sink was obtained, and the mean sediment concentration and hydraulic roughness at the outlet of the settling tank were obtained. The calculated values were compared with the results of the prototype observation and the experimental study to prove that the new method Have more precision.
