Abstract:
One of the most important elements in the development of human civilization is the prospect and availability of groundwater.
Ethiopian farmers depend upon the rainy season for farming practices. The natural and man-made factors create extreme
poverty and suffering for the farming communities and the country at large. Ethiopia's potential for its groundwater is not
fully understood. Also, a high-resolution groundwater prospect mapping availability is restricted to only a few localities of
the Ethiopian Rift Valley. Therefore, this research was conducted to demonstrate how well remote sensing and GIS tech
niques combined with weight assignment utilizing an analytical hierarchy process can be used to decipher groundwater
prospects with the least amount of resources and the highest degree of accuracy. The priority of geology/lithology, slope,
lineament, density, geomorphology, drainage density, soil, land cover, and rainfall is established in the Ethiopian Main Rift
Valley through the validation process by borewell locations and their safe yields, which also reveals the sustainability of
groundwater resources. The findings show 91.53% of agreement and 8.47% of disagreement during the validation of the
study. Additionally, this analysis shows that close to 59% of the Mojo watershed is classified as having good to very good
groundwater prospects, while approximately 31% of the area is classified as a moderate groundwater potential index. And
the remaining 8.31%, of the area comes under the poor to very poor groundwater potential index.
