Analysis of dynamic characteristics of groundwater due to rainwater collection measures
This study investigates the groundwater dynamics due to two rainwater collection measures including permeable pavement and sunken green space.A primary school in Huaibei Plain is chosen as the study area.A numerical flow model is developed for quantitatively analyzing the responses of the groundwater level and exploitable amount to the two rainwater collection measures under different precipitation frequencies.Results suggest the exploitable amount of groundwater can be increased by 2.78％,2.79％and 2.81％for the precipitation frequencies of 25％,50％and 75％,respectively.The rainwater collection measures raise the groundwater level by 0-0.24 m under the average annual rainfall in 2017-2018.The ratio of such an increase to the aquifer thickness falls in the range of 0-0.96％.This study may be of importance in managing the groundwater resources in the study area.
