GROUNDWATER RECHARGE BY RAINWATER HARVESTING, G12-13 / H12-13, ISLAMABAD, PAKISTAN

Abstract

Water is the greatest blessing of Allah. We cannot imagine life without water. The study of water is a significant part of geology, known as hydrogeology; how water and rock interact with each other. Rocks can facilitate water and provide it path to recharge groundwater. Groundwater availability changes due to nature of terrain. Groundwater is depleting year after year. The scarcity of groundwater has affected all over Pakistan. The aim of the study is to recharge groundwater in the study area of Islamabad, the capital city of Pakistan. Precipitation water every year floods to sea, that could be managed to utilize effectively to recharge groundwater for future use. 20 stations were covered to analyze fractures of rocks by circle inventory method and window method to calculate the fracture density, porosity and permeability to indicate ideal sites for recharge shafts and pits in Islamabad. Water flows from north to south, rainwater could be infiltrate to recharge groundwater as Miocene age Murree and Kamlial Formations are exposed in study area having suitable porosity and permeability to recharge groundwater
