Özet:

With the effect of climate change, the number of meteorological disasters is increasing year after year around the world. In our country, it has been observed that there has been a great increase in flood disasters due to heavy rains in recent years. Çoruh Basin is considered as one of the important basins in terms of either its topographic, human and hydrometeorological features or flood disasters based on frequently flooding in the streams of the basin. For this reason, it is necessary to evaluate the streams in the basin hydrologically in order to prevent possible loss of life and property and to minimize the damages due to flood disasters. In this study, it is aimed to produce flood inundation maps using a hydraulic model. For this purpose, Pona and Örtülü Creeks located in the Çoruh basin and within the borders of Ardanuç district of Artvin province, were selected as the study area. Several software were used in the study, ArcGIS for terrain modeling, spatial analysis and mapping, FLO-2D and HEC-RAS for hydraulic analysis. As the results of the study, hydraulic modeling of the relevant creeks was performed, maximum water depths were obtained, flood inundation areas were determined and flood inundation maps were produced.
