Water table level is an important feature in subterranean hydrology and is relatively easy to observe. Groundwater recharge is a cause of water table rise and the carrier of contaminants to groundwater. However, groundwater recharge is an elusive quantity because accurate field measurements are difficult to obtain. A study of the relationship between groundwater recharge and water table rise is advantageous because it will allow the evaluation of groundwater recharge based on field-measured water table rise. The equilibrium condition is defined as a condition when the water energy in a region reaches a constant. A published record (Holmes and Colville, 1970) indicated that the water energy near a water table approximated the equilibrium condition. An analytical relationship between groundwater recharge and water table rise is derived based on the equilibrium condition. The analytical relationship was tested using measured water table levels during two storm events and produced promising results.
