基于流量衰减分析的次降水入渗补给系数计算方法
Methods of calculating recharge coefficient of precipitation event based on spring recession analyses
摘要
Abstract
Recharge coefficient of precipitation event,which is controlled by climate,topography,geology,etc,is an important parameter in the evaluation of groundwater resources.This paper discussed the calculation methods of the recharge coefficient of precipitation event in the Wulongdong underground river located in the Xiangxi River basin in Yichang of Hubei Province.Based on the spring recession analyses,we found a new way to calculate the recharge coefficient of precipitation event,examined its characteristics and controlling factors,and certificated the scientific rationality of the calculating results.The results demonstrate that the hydrographs of the Wulongdong river can be described into segmented recession curve;precipitation intensity and underlying surface conditions before rain are the main influence factors for recharge coefficient of precipitation event calculation;the calculation method of recharge coefficient of precipitation event is rational and feasible,which has application value in karst water resources evaluation.关键词
