Yamula Dam that has been constructed in Kayseri is one of the most important projects regarding the irrigation of agricultural lands. The total area of the collected water body was reached in 2005 as planned before, and electricity production started. Together with the realization of the project, it is planned to use agricultural lands in basin more efficiently and productively. In this study, it was aimed to determine the hydrological structure of Yamula Basin and potentially irrigable lands by using geographic information systems and remote sensing technologies. The hydrological structure was determined using digital elevation model. The land use map was prepared by using Landsat satellite image for the year 2016. The analysis and queries were carried out by overlapping the land use, land use capacity, topographic maps and sub-basin layers. The potential agricultural lands were determined in accordance with the results obtained from the spatial analysis.
