Özet
Floods are one of the most important natural hazards in the world and in Turkey, and depending on their severity and formation conditions, they can cause disasters by creating diverse negative impacts sources from natural effects or human intervention. In this study, flood susceptibility map was prepared by conducting flood analysis of Çerçi River in Fethiye District of Mugla Province, Turkey. While determining the flood susceptibility of Çerçi River, the geologic, geomorphologic, sedimentological, and hydrological data of the region were used. The physical properties of the study area were investigated, and it was observed that the fine sand, silt, and clay sediments were dominant. As a result of the soil tests performed with the samples, it was determined that the dominant soil class was medium plasticity inorganic clay (CL). For performing spatial analyses, the ArcGIS 10 software from ESRI Inc. and its module Spatial Analysis were used to map susceptible areas to floods. Different maps of the study area, such as slope, elevation, proximity to the rivers, geology, land use and aspect were employed in ArcGIS software using the weighted overlay method. As a result, the flood susceptibility map of the study area was obtained. Based on this susceptibility map, 17.64% of the study area is located in high susceptible areas. Very high susceptible areas include the parts of Fethiye District located in the southwest of the study area. © 2021, Hacettepe Universitesi Yerbilmleri. All rights reserved.
