Estimation of Ground Water Recharge Using Soil Moisture Balance Approach

Abstract

The amount of water that may be extracted from an aquifer without causing depletion is primarily dependent upon the ground water recharge. A quantitative evaluation of spatial and temporal distribution of ground water recharge is a pre-requisite for operating ground water resources system in an optimal manner. This paper presents a methodology with step-by-step procedure to determine the ground water recharge by soil moisture balance in the unsaturated zone.
