Recharge Estimation in Karst Aquifers by Applying Water Level Fluctuation Approach

Abstract

In arid and semi-arid areas, quantifying groundwater recharge is an essential issue for groundwater resources management. Since recharge is a function of many parameters such as level of karst development and climatic conditions, then selecting the best technique of recharge estimation that takes these parameters into consideration is still an issue. This paper presents an alternative technique for estimating annual groundwater recharge using the fluctuation of water level within an aquifer during a specific time interval as a result of the water balance of inflows and outflows.
