摘要
依据复杂网络河的特点及其内在联系,本文建立了其特征矩阵及由NewtonRaphson格式表述的隐式圣-维南差分方程组的系数矩阵。经输入边界条件及解方程组,可得到不同时段各支段上、下游端点上的水位和流量值。
Based on the features of network rivers and its internal relations, the characteristic matrix and the coefficient matrix in the Newton-Raphson format of the implicit Saint Venant difference equations are established in this paper .The values of water level and discharge at different times at the upstream and downstream nodes of the network can be obtained and the results are in good agreement with the observations.
