| Abstract
|
:
|
According to literature, natural disasters are increasing worldwide. Among them, flood is the most common and has the most impacts. Because of global warming and climate-patterns changing, frequency of floods has increased significantly. Also, the greatest impact among the human-oriented reasons are urbanization and industrialization. With the spread of urbanization, population in cities around the world has increased rapidly; natural areas have been destroyed, cities have been expanded. These changes have increased fragility in cities. Therefore, objective of the study was to determine flood risk areas and minimize negative impacts of floods. Accordingly, the study area; the Menemen Plain and its surroundings were found worthwhile to examine due to its topographic, climatic and hydrological structure. In this study, weighted-overlay analysis method was used in ArcGIS to determine flood risk areas employing six criteria. Therefore, six criteria that have an impact on flooding were identified as; (1) slope, (2) elevation, (3) distance from rivers, (4) distance from junction-points of river, (5) land use/cover, and (6) rainfall. The weights of criteria were assigned by land and literature investigation. According to the study, the highest risky flood locations with more population were seen as Emiralem, Kesik, Buruncuk and Çavuşköy settlements. On the other hand, medium flood risk settlements with more population were found as Seyrek, Yahşelli, Sasalı and Yenibağarası. Consequently, resilience and mitigation strategies were identified. It was stated that flood risk management should be managed in a participatory manner with a holistic approach and public-private-individual partnership with structural, non-structural measures.
