Accurate estimation of the groundwater budget requires good estimate of flux across the boundary of a region. Different methods and techniques are available to estimate recharge to groundwater; however methods for estimation of flux across boundaries are not available. The present article represents a GISbased methodology to estimate the groundwater flow rate and volume of water flux across the boundary. Groundwater level data (pre-monsoon and postmonsoon) are used to derive detailed maps like flow direction, hydraulic gradient and velocity component perpendicular to the boundary.
