Appropriate quantification and identification of the groundwater distribution in a hydrological basin may provide necessary information for effective management, planning and development of groundwater resources.Groundwater potential assessment and delineation in a highly heterogeneous environment with limited Spatiotemporal data derived from Gelana watershed of Abaya Chamo lake basin is Paddles performed, using integrated multi-criteria decision analysis (MCDA), water and energy transfer between soil and plant and atmosphere under quasi-steady state (WetSpass) models.The outputs of the WetSpass model reveal a favorable structure of water balance in the basin studied, mainly using surface runoff.The simulated total flow and groundwater recharge are Lacrosse Sticks validated using river measurements and estimated baseflow at two gauging stations located in the study area, which yields a good agreement.

The WetSpass model effectively integrates a water balance assessment in a geographical information system (GIS) environment.The WetSpass model is shown to be computationally reputable for such a remote complex setting as the African rift, with a correlation coefficient of 0.99 and 0.99 for total flow and baseflow at a significant level of p-value.
