摘要
多沙河流洪水演进中的泥沙输运计算十分重要,水动力学方法复杂且计算量大,水文学方法简单但只针对水流过程计算。为了同步实现水沙过程的快速有效计算,在传统马斯京根流量演算方法的基础上,拓展出马斯京根输沙率演算方法。将该泥沙输运的水文学计算方法应用于黄河中下游河道流量与输沙过程演算,演算得到的泥沙输运结果有一定精度,证实了该方法是可行的,可作为多沙河流水沙计算的一种快速有效的水文学方法。
Sediment transport calculation is very important in flood routing of sediment laden rivers.The hydrodynamics methods are complex and require expensive computing cost,while the hydrologic methods are simple but only for the water flow processes.In order to realize the efficient calculation of sediment transport process synchronously,the Muskingum method for sediment routing was derived from traditional Muskingum method for flood routing.This method was tested against flow and sediment transport in the middle and lower reaches of the Yellow River.It finds out that sediment transport results have satisfactory precision which demonstrate the applicability of the present method in fast predicting downstream sediment transport in sediment laden rivers.
