摘要
Abstract
In order to study the design flood of extra small watersheds under different underlying surface conditions in Guangxi,five extra small watersheds located in different regions of Guangxi are selected as the research objects.The design flood peak flow and maximum 24-hour flood volume of five common frequencies under different types of underlying surface conditions are calculated respectively.The influence of underlying surface on the design flood peak flow and maximum 24-hour flood volume is analyzed.The variation law of design flood peak flow and maximum 24-hour flood volume under different underlying surface conditions is summarized,and the change trend is quantified.The results show that for the same study area,the change of underlying surface will have a certain impact on the design flood peak flow,and the impact on the maximum 24-hourflood volume is relatively small.The research results have certain reference value for the flood research of pumped storage power stations and extra small watershed water conservancy projects in Guangxi.关键词
