Summary
Most site hydrogeological studies include analysis of water-level transients; for example, pumping-test interpretation, evaluation of aquifer recharge, estimation of surface/subsurface water interactions, etc. However, identification of the physical sources causing spatial and temporal variation of aquifer water levels is challenging [cf.Vasco et al., 2000].
