Flood is a natural disaster in which the amount of water in the riverbed cannot fit into its cross-section for various reasons and damages the surrounding lands, settlements and living things. To reduce the material and non-material damages of the floods affecting our lives, the mechanism of the flood disaster must be well known, and measures should be taken before flooding. For flood management plans, it is important to determine the areas that may flood before the floods occur and to determine the economic losses of these areas. One of the most important steps in flood management is flood modeling. In this modeling, flood spread area, water height, water velocity and economic losses can be determined. In this study, two-dimensional flood model of the Mert River Basin, located in the Central Black Sea Region, was investigated. In our country, there are no damage functions used in determining the economic losses that may occur as a result of floods. This study estimated flood risk and economic losses using damage curves models from European countries. Hydraulic model was created by using with HEC-RAS for 50, 100, 500 and 1000 years return period. The study exposes those flows cause an estimated damage of 150-500 million -, affect 9 and 12 thousand people. These estimates and comparisons show applicability of the damage functions suggested.
