Özet
The Harran Basin is in the Upper Mesopotamia territory, and it is an important basin, in which agricultural activities have been conducted for more than 4000 years. This basin has the most valuable lands of not only Turkey but also the Middle East. Within the framework of the GAP project, the agricultural activities are maintained through the water provided from the Ataturk Dam, employing the irrigation in the plain via surface irrigation and in other places via groundwater. Therefore, it is of vital importance for the provision of sustainable water resources to determine the hydrological and hydrogeological characteristics feeding the groundwater, which is the alternative water resource of the basin. In this study, DEM, geomorphology map, slope, drainage, and drainage density maps were produced as the hydrogeological parameters of the Harran Basin, and geology, groundwater level map, and thematic maps demonstrating the aquifer status were produced as the hydrogeological characteristics. With the help of these maps, the groundwater and surface water resources are evaluated. This study aims to evaluate parameters such as drainage density (DD), geomorphology, geology, rainfall, slope, and land use (LU) which affect the formation of groundwater and to correlate with groundwater yield maps obtained from drilled boring data in the basin. The ArcGIS 10.2.2 program, Arc Hydro, and Spatial analyses extension were used to obtain hydrological and hydrogeological thematic maps. The study concludes the most groundwater potential area remains a fertile region where the slope is lowest, and the geomorphological flat plain has a high drainage density rate in which infiltration was more intense. The region equally has a geologically appropriate aquifer.
