根据实测雨洪资料,着重研究和总结应用推理过程线法分析小流域洪水汇流参数 M 的可行性,探讨 M 参数的区域性规律.成果说明,M 参数的稳定值是存在的,为推求设计条件下的 M 值提供了依据.M 参数的区域性规律,为无资料地区移用创造了条件。M 参数经综合,按下垫面分类办法分为非岩溶流域和岩溶非岩溶混合流域两种类型区,并建立计算 M 参数的经验公式,为中小型水利水电工程推求设计洪水提供参考。
Based on the observed rainfall data, the feasibility and feasibility of using the line method of reasoning process to analyze the flood confluence parameter M of small river basins are discussed and summarized, and the regional laws of M parameters are discussed. The results show that the stable values of M parameters exist, Under the M value provides basis.M regional parameters of the parameters for the transfer of non-accredited areas to create the conditions. The M parameters are classified into two types of non-karst basins and karst non-karst basins according to the classification method of surface classification, and empirical formulas for calculating M parameters are established to provide reference for the design flood of small and medium-sized water conservancy and hydropower projects.
