Flood disasters are often experienced in Amik Valley, one of the most important valleys in Turkey. These natural hazards generated due to the effects of natural and human features of the valley have caused serious economic damage in recent years. In contrast to previous studies undertaken in the valley, current study aims to analyze the natural hazard along with risk potential and index in order to map and explicate the possible flood risk. Topography sheets scaled 1/25.000 and 1/250.000 and Digital Elevation Model (GDEM) data were used in the study as materials. Other data used in the study were obtained from 2012 flood identification and village briefing reports, Turkish Statistical Institute data and telephone interviews. Mapping and analysis were done by utilizing Geographical Information Systems (GIS) software ArcGIS/ArcMAP 10 package program. In addition, Cnes/Spot Image satellite images in Google Earth (KMZ) format dated 2012 were utilized with the help of Remote Sensing (RS) techniques. The obtained data were checked in situ via field surveys and missing points were completed. Method used in the study was based on adapting the system developed by Tran et al. (2008) to the study area. Study results show that the highest possible flood risk (413.96 km² - 43.49 %) in Amik Valley is observed in areas with medium risk located in the north and central parts of the valley. The areas with the highest flood risk in the valley are the western and southern parts of Hatay Airport and the rural areas around the district centers of Kumlu and Reyhanlı and the areas with the lowest flood risk are found to the east of the valley. Current study undertaken with the help of Geographical Information Systems (GIS) methods and techniques serves as a suggestion to solve the problems related to flood risk experienced in Amik Valley. Findings and results of the study will prepare the foundation for planning in the valley.
