Research of matrix mark method for river network flow modeling
摘要
Abstract
The implicit difference scheme for solving 1 D Saint-Venant equations is of good stability, but large-scale coeffi-cient matrix needs to be generated and solved for simulating river network flow. The topological structure of river networks is ab-stracted as a directed graph from graph theory, and the incidence matrix is established to generate the coefficient matrix automati-cally. The object-oriented matrix mark method is proposed on the basis of matrix mark method, which is more universal and flexible. The practical computation and the sensitivity analysis of the relaxation coefficient show that the modified method can sim-plify the structure of the calculation program, which is effective and stable.关键词
