The significant decline of groundwater lev e l every year causes a repeated groundwater crisis in Bandung area, west Java, Indonesia. Information about ground water recharge becomes important in order to be able to identify the relationship between input and output water in this region. Although, various techniques are available to approach the estimation of recharge, the lack of artificial wells and records of the groundwater fluctuation in the recharge area obstructs the recharge estimation. In the present study, we used the available data of streamflow hydrograph to assess the potential amount of a groundwater recharge based on base-flow recession. The results indicated that the recharge was approximately 566.36 mm/year and 292.39 mm/year or 20.97 and 14.59 percent of the rainfall nets in 1992 and 1993, respectively. The estimated groundwat er storage was approximately 16.15 % in 1992 and 4.15 % in 1993 of rainfalls.
