流域洪涝指数方法研究

Study On Basin Flood Index Method

应用降水产生流量过程线的变化原理 ,研究了一个考虑前期影响雨量的设计洪涝面雨量计算方法。然后复核水位与设计洪涝面雨量的关系，确定出各级洪涝指数的设计洪涝面雨量的大小。

Based on changing principle of flow procedure lines produced by precipitation, one calculating method for designing area precipitation has been studied, in which the earlier stage precipitation must be considered. After that, checking the relationship between designing area precipitation and water level, the scales of designing area precipitation can be defined for each grade of flood index.
