Groundwater Modelling: Integrated approach with remote sensing, Geographic Information Systems (GIS) and more traditional fieldwork techniques was adopted to map the groundwater potential sites Northern Adaa Plain (Modjo Catchment).Seven thematic maps was produced. GIS analysis was conducted and reclassification was done for each factor maps. Weighted Linear Combination (WLC) model was built and used to generate groundwater potential map. The validity of the model developed was tested against the borehole data, where out of 107 boreholes 50 are on very good and good zones, 37 on moderate...
