Flooding, one of the most important meteorological disasters, is a sudden and highly effective disaster. It is very important to use the methods accepted in the international academic community by using Geographic Information Systems (GIS) to avoid being unprepared for this disaster, to fight and to take necessary precautions. One of these analysis methods is Analytical Hierarchy Process (AHP), also known as Analytical Hierarchy Process (AHP) or Multi-Criteria Decision Making Process (ÇKKVS). In this study, the Behzat River Basin, located in the south of the Central District of Tokat, which has suffered from flood disasters many times from 1839 to 1961, and has lost hundreds of lives in the historical process, was examined. In the light of data obtained from many national and international institutions such as SentinelHub, NASA, Corine, HGM, MTA, AHP was created. It was observed that the southwestern and northern sections of the basin, which has an area of approximately 25,041 hectares, consist of areas highly vulnerable to flood disasters. According to the calculations, approximately 9747 ha (38.9%) of the basin is moderately and 1372 ha (5.4%) is highly vulnerable to flood disasters. Based on the results obtained, it is aimed to prepare the relevant stakeholders in the disaster management process.
