The present study aims at using GIS hydrology tool for calculating inflow/outflow fluxes across the boundary of a study area in a situation where physical boundaries in the vicinity of the study area cannot be identified. This approach has an edge over the simplest approach of no flow or constant head boundaries alone, which may be far from reality. The reported methodology will improve groundwater modelling in the areas where the hydrological cycle is predicted because of climate change.
