A Flood Routine Model on Huai He Midle Stream

According to the characteristics of Huai He river basin,a flood routine numerical model is established in this paper.This model is based on hydrodynamics method of combination 1-D channel flow modeling with 2-D flood plain flow modeling,and hydrology method of no data areas modeling.The technology and skill of solving the combination 1-D flow wish 2-D flow and treating the runoff in no data areas are developed,which are key to successful modeling.It is showed in the 9 times floods modeling calculations that the model has high accuracy,practicality,flexibility and universality.The model is a advanced tool of Huai He river basin flood control planning and can be used in other basins.
