湖北襄阳市降水入渗补给系数分析

Analysis of infiltration Coefficient in Xiangyang City,Hubei Province

在水资源评价中,降水入渗补给系数是一个非常重要的参数。利用实测资料统计分析了湖北襄阳市降水对浅层地下水资源的补给,分析雨前不同埋深条件下,次降雨与地下水位上升的关系,最终得到襄阳市多年降水入渗补给系数及年降水入渗补给系数的变化规律,为科学合理地利用地下水资源提供依据。

Coefficient of infiltration is a very important parameter during water resource evaluation. According to survey data, this paper analyzed the rain water infiltration for shallow groundwater resources in Xiangyang City,Hubei Province. The connection between single rainfall event and rising of groundwater level was given base on analysis result of different depths conditions prior to rainfall. At last, the changing pattern of variation coefficient in many years and annual coefficient of infiltration were obtained in Xiangyang City, which provide reference for scientific management groundwater resources.
