基于免疫克隆算法的马斯京根洪水演进模型分析-analysis of muskingum flood evolution model based on immune clone algorithm.docx

AbstractThe flood has been impacting on humans survival and development for a long time. And the occurrence of a larger flood tends to bring serious casualties and property losses. However, all the researches should be based on the understanding of the flood characteristics, either in the flood forecasting or in the flood damage assessment, even in the comprehensive management of the basin. Obviously, the most important part which people should know is the law of the flood routing. Thus, this subject has been discussed by many experts and scholars at home and abroad. And a lot of research results have been given by them.As the largest tributaries of the Yellow River, Weihe River runs through Shanxi Province from west to east. And it was called the mother river by Shanxi people. However, with the deterioration of the natural environment, it was caused plenty of issues, such as water pollution and sediment deposition. The frequent occurrence of floods caused serious threat of life and property to people.A Muskingum flood-routing model based on Immune clone algorithm was proposed by the author. Comparing with the traditional genetic algorithm and least square method, the precision has been improved. The result shows that this model can be used in the research of river flood routing.In this paper, the lower Weihe River was divided into three regions: Zhangjiashan~Lintong 、 Xianyang~Lintong and Lintong~Huaxian. The runoff from Zhangjiashan was described as a branch of Weihe River. And it was overlaid with the runofffrom Xianyang in the station of Lintong according to the same time series, after the calculation of the flood routing. The result of the overlying was disposed as the inflow of Lintong~Huaxian.For each region, using historical flood information, the parameters were rated separately combined with the practical significance of the parameters. Aiming at the problems of longer river and greater flood, this paper puts forward Muskingum segmentationand delamination
