【摘要】 提出了一种水流路径算法,该算法通过以各格网点为中心建立3×3窗口内基于6条拉格朗日曲线构成的局部曲面,再利用当前点在局部曲面中的等高线曲率选取合适的单流向算法以确定当前点的水流方向及其向下游点的流量分配比例。最后通过实例证明了该方法在水流累积量计算中的良好效果。更多还原

【Abstract】 In this paper,a flow path algorithm is proposed,a piece of partial surface based on 6 curves using Lagrange formula is established through every grid point in the 3×3 grid points area which have x,y and z values,and through the contour curvature of the current center grid point of the partial surface,the right single flow direction algorithm will be selected so as to calculate the flow direction of current point and its distribution ratio of water flow to its downstream point.Finally,good results using this method in the accumulation of the water are proved.更多还原
