Groundwater accounts for one-third of all freshwater abstractions globally [7]. In many regions of the world where water supplies are limited, groundwater is a crucial natural resource for any economic and social growth [8]. Groundwater supplies are a necessity for all economic activity, both internally and outside. However, a study that combines remote sensing and GIS data can offer a good platform for the converging analysis of massive amounts of data using very advanced cognitive process techniques for groundwater exploration. Nations like Ethiopia are seeing a rise in groundwater demand as a result of the nation's fast urbanization, population growth, and economic development. In the area under examination, groundwater is the most often used resource for agriculture, animal husbandry, and the provision of drinking water. The Lower Omo-Gibe watershed groundwater potential zone mapping will have a significant impact on the sub-basin. Since the Lower Omo-Gibe watershed is the main source of the Omo River, mapping the underground water would improve the nation's groundwater resources' sustainable management. Because of this, the current study is interested in delineating the groundwater potential zones within the study area using remote sensing and GIS technology. Seven determining elements were taken into consideration for the study: slope, landuse landcover, Lineament density, Geology, Elevation, Soil texture, and Drainage density. In order to ensure sustainable management and growth of the resource, groundwater exploration has recently seen a rise in the

The demand for and investigation of groundwater are occasionally increased by the ever-increasing population and abrupt climatic changes. To delineate groundwater potential (GWP) zones in the Lower Omo-Gibe Watershed, Omo-Gibe Basin, Ethiopia, an integrated strategy of remote sensing (RS), geographic information systems (GIS), and multi-criteria decision analysis (MCDA) using analytical hierarchical process (AHP) was used. For this purpose, seven GWP influencing thematic layers comprising lineament density, slope, soil, drainage density, landuse landcover, geology and elevation map were used. Scale values for the classes and thematic layers within them were determined using Satty's AHP and based on expert and literary judgment. The thematic layers have been integrated via their weights/rates using weighted overlay spatial function tool of ArcGIS to provide GWP map. The result shows that GWP map comprises very good (13.79%), good (40.68%), moderate (27.06%) and fair (18.45%) zones.
