Flood risk analysis of Çeşneli stream by using gis

Various methods are used for flood risk analysis. In recent years, studies on this topic have focused on geographic information systems. Generally used calculations for determining flood risk are based on open channel flow. After obtaining the digital maps and transferring the desired data as a model, one dimensional analysis was performed with Hec-Ras package program. In this study, flood risk analysis was carried out on Çeşneli Stream in the Eastern Mediterranean Basin. Digital maps of Mersin province were obtained by using Netcad software and raster data were obtained and transferred to Hec-Ras. The data obtained as a result of the analyzes were used to create flood risk maps.
