RECHARGE CHARACTERISTICS OF A PHREATIC AQUIFER AS DETERMINED BY STORAGE ACCUMULATION

Quantifying of aquifer recession and water table fluctuation in the case of shallow aquifers. Approaches to recharge estimation in phreatic aquifers by fluid-mass-balance method and integral hydrograph separation method. A test technique to quantify recharge is developed on spring response alone. Discussion on examples of a cumulative storage accumulation curve (CSAC) interpreted for well hydrographs. Application of the storage accumulation method, fitting of stage discharge relationships. Relation between measured spring flow and water table elevation and comparison of recharge estimated by various methods for wells.
