Flood Prioritization Watersheds of the Aras River, Based on Geomorphometric Properties: Case Study Iğdır Province

Drainage watershed morphometry plays a major role in terms of understanding flood dynamics. Flood potentials are explained considering the linear, areal, and relief features watersheds. In general, there number geomorphometric indices description these features. The formal geometries, geomorphology, geology, general climate characteristics, etc., which play decisive potential watershed, can be determined relatively with morphometric indices. this study, 35 different river watersheds draining their waters to Aras, located center Iğdır Province, were examined. Geographic information systems (GIS) statistical software chosen analyze calculate for research. events occur study evaluates using 14 evaluation results obtained, values that have high impact on floods ranked according priorities. These evaluated priorities analysis principal component methods. watersheds, obtained through two methods, classified as high, medium, or low common based is 8 "high" priority, 11 "medium" 7 "low" priority. According results, it seen priority correspond areas where occurred.
