摘要
高海拔山丘区河流夏讯洪水具有暴涨暴落,易成灾害的特点。因此对其洪水特性分析十分必要,文中以汤旺河流域五营站、伊新站和晨明站实例水文数据为例,从流域洪水的来源组成、传播时间、出现频率、洪峰特点等方面做了初步分析。简要得出流域洪水自上而下的部分基本特征。
The summer flood of rivers in high-altitude hilly areas has the characteristics of sudden rise and fall,and is easy to become a disaster.Therefore,it is necessary to analyze the characteristics of flood.In this paper,the hydrological data of Wuying Station,Yixin Station and Chenming Station in Tangwang River Basin are taken as an example.This paper makes a preliminary analysis of the source composition,propagation time,occurrence frequency and flood peak characteristics of the flood in the river basin.Thus,part of the basic characteristics of the basin flood from the top to the bottom are briefly concluded.
