An analysis of the coefficient of replenishment from infiltration of precipitation

In this paper,data of infiltration of precipitation measured with the underground infiltration instrument are used to analyze the variation in the coefficient of replenishment from infiltration of precipitation.The data were collected from the Ranzhuang water resources experimental station in Hebei province,the Wudaogou water resources experimental station in Anhui province and the Taigu water resources experimental station in Shanxi province.The values of the coefficient of replenishment from infiltration of precipitation are obtained under the conditions of different lithologies,annual precipitations and depths to groundwater levels.The best depth to groundwater levels and the existence of the stable point of the greatest depth to groundwater levels are also discussed.
