摘要
提出一个模拟网河区洪水过程的交错格点显式差分法．该差分格式能自然适合水流计算的边界条件，处理叉口简单、存储量小，并且计算结果合理。
A kind of explicit difference method of cross grid, which is used to forecast flood in a network of waterways, is developed in this paper. The difference scheme is naturally suited to the boundary conditions of hydraulic computation and deals with fork link easily. It has the advantages of small computer memory, simple compute program and reasonable caculation results.
