In addition to helping water managers balance their water budget, groundwater recharge also provides an opportunity to create habitat for wildlife. Given a sufficiently deep and expansive aquifer, however, groundwater flow is neither upward nor downward throughout most of the extent of the flow system (Figure 3). These four methods are; the soil water balance method, Chaturvedi formula, the seasonal recession (Meyboom) method, and a well level data method. These studies should involve measurements of groundwater discharge and water balance at observation stations with appropriate instrumentation (Fig. The flux of groundwater accretion is positive when recharge occurs and negative when discharge occurs. . Check Dams: Groundwater recharge may also occur from surface . This guide highlights recharge basin management strategies that create wildlife habitat and . Subsurface Groundwater Recharge Groundwater recharge is an important process for sustainable groundwater management, since the volume-rate abstracted from an aquifer in the long term should be less than or equal to the volume-rate that is recharged. We want to hear from you. Only when the number of source locations is estimated with some degree of certainty that the characterization of the sources in terms of location, magnitude, and activity . Discharge of groundwater occurs when water emerges from the ground. A common example is of an overflowing unconfined aquifer. More information.
