汊点分沙
4) junction equations
汊点方程组
1.
Hydrodynamic model for river network is set up based on one-dimensional Saint-Venant equations, junction equations in all river junctions and boundary conditions.
利用一维Saint Venant方程组、河网汊点连续方程及边界条件建立了河网水动力学模型 ;采用Abbott六点隐式差分格式离散控制方程组 ;求解河网时 ,将河段方程自相消元 ,得到以汊点水位为基本未知量的汊点方程组 ;采用汊点优化编码来降低汊点方程组系数矩阵的带宽以提高计算精度和节省计算耗时。

补充资料：汊河
1.河流被沙洲或岛屿分成两股或两股以上的水流，其宽度﹑深度和流量较小的称做汊河。
