Abstract

This study was conducted to determine potential groundwater storage areas in the semi-arid Oltu Basin in northeastern Turkey. The groundwater potential of the basin was analyzed by evaluating eight geographical factors: lithology, linear density, soil depth, land use, precipitation, geomorphology, slope, and drainage density. These factors were classified and weighted using remote sensing, geographical information systems (GIS), and the analytic hierarchy process (AHP). The obtained data were modeled using ArcGIS software, and a potential groundwater storage map of the Oltu Basin was created. The results show that there is a high groundwater potential in areas of the basin close to the stream bed, while the groundwater potential is low in mountainous and steeply sloped regions. The study provides significant findings for sustainable water resource management in the region and future water resources planning.
