| Abstract: | Numerical simulation of the complex terrain long river flow form will meet many difficulties in the simulation process. This paper takes SuiNing reach city for example to analysis two dimensional numerical simulation, and uses hot start, mesh refinement different to processing difficulties .The results show that mathematical model calculated value and the test value can be better coincidence, which will provide a reference for river flow morphology study . |
