拒马河干流典型场次暴雨洪水对比分析
Comparison and analysis of typical rainstorm floods in the main stream of Juma River Basin
摘要
Abstract
In order to clarify the typical rainstorm flood situation of the main stream of the Juma River,by analyzing the hydrological data of Zijingguan and Zhangfang in Juma River Basin,combined with the rele-vant meteorological background data,the characteristics of"7·21"and"23·7"rainstorm floods were com-pared and analyzed from two aspects of rainfall and flood.The results showed that because of the different rainfall characteristics of"7·21"and"23·7",the flood in the Juma River basin showed different charac-teristics.The runoff yield in Zijingguan-Zhangfang interval was higher than that in the upper reaches of Zi-jingguan.Affected by the difference in spatial and temporal distribution of rainfall,the flow processes of Zi-jingguan and Zhangfang sections in the"7·21"flood showed a single peak shape,while the two stations in the"23·7"flood showed a multi-peak shape,and the fluctuation speed of the"7·21"flood was faster than that of the"23·7"flood.This study provides reference for better flood and drought disaster prevention in the Juma River basin in the future.关键词
