Taşkın Risk Alanlarının Analitik Hiyerarşi Süreci Kullanılarak Mikro-Havza Ölçeğinde Değerlendirilmesi.

This study aims to determine the areas with flood risk in the micro-catchment where a university campus is located and to evaluate the situation by using multi-criteria decisionmaking method. All the spatial analyses to predict flood risk levels were carried out in the Geographical Information Systems environment. The method consists of seven variables: flow accumulation, rainfall intensity, geology, land cover/use, slope, elevation, and distance from drainage networks. Different weights were given to each variable, and these weights were calculated with the Analytical Hierarchy Process. The information covered by different variables according to their weight values was overlayered and a flood risk map was created. Consequently, Siirt University Kezer Campus has been found to be located in an area with moderate flood risk. Considering the distribution of land cover/use, the riskiest areas are areas with dense urban structure and represented with 14.02%. The areas with the least risk are forested areas, represented by 0.1%. The percentage sum of the areas with the highest and the highest flood risk in the research area is 21.62%. Additionally, it is among the results that the method is useful especially in small scale and quick response studies, and applicable especially in sub-scale planning studies. [ABSTRACT FROM AUTHOR]
