摘要：In this study, it is aimed to develop the flood risk analysis of Porsuk River, which is responsible for naming of the Porsuk Basin sub basin of Sakarya Basin, by utilizing the methods of Remote Sensing (RS) and Geographical Information Systems (GIS). In addition, flood elevation effects of Porsuk River in Eskişehir city and the regions around were investigated. Necessary data for study were obtained from Eskişehir 3. Regional Directorate of State Hydraulic Works archives. For analyses, the cross section of Porsuk River was defined in the Hydrologic Engineering Centers River Analysis System (HEC-RAS) software. Subsequently, recurring periods of 50, 100 and 1000 years discharge of Porsuk River which is calculated as 51.83 m3/s, 60.15 m3/s and 86.66 m3/s respectively were inputted in the software to obtain analysis results. Obtained results from the present study and topographic data were compared and interpreted. As a result, elevation of flood and its risks for urban regions were studied and presented.
