本文仅对一维河流数值模拟算法的近期发展作一简短报道，内容有当今数值模拟对算法提出的具体要求，动床一维非恒定流算法，泥沙模型中的饱和和非饱和输沙模式嵌套算法，一、二维泥沙模型嵌套算法等，并指出交叉边缘学科的渗透和多学科的结合以及应用是今后河道数学模型研究和发展的重要方向．
In this paper, we only present a brief report on the recent development of one-dimensional river numerical simulation algorithms. The content includes the specific requirements of the current numerical simulation algorithms, the one-dimensional unsteady flow algorithm of moving bed, the model of saturated and unsaturated sediment transport in the sediment model Nesting algorithm, one-dimensional and two-dimensional sediment model nesting algorithm and so on. It is pointed out that the infiltration and multidisciplinary combination of cross-boundary disciplines and their application are the important directions for the research and development of mathematical models of river courses in the future.
