Comparison Of 2d Hydraulic Models For Flood Simulation On The Mert River Turkey

As well as all over the world, Turkey exposures to floods more frequently as a result of climate change. The study area, Mert River is located in Samsun city north of Turkey and also frequently exposed to floods and flood management studies in the region are carried out in progress by local administrations. The aim of this study is to compare different hydraulic modeling methods on Mert River, mainly related to floodplain modeling. Therefore, different hydraulic models have been applied to the Mert River. Two types of 2D models are examined in this paper, these are respectively MIKE 21 and FLO-2D. In this study a comparison of the simulation results of models are performed. By these comparisons, the benefits and limitations of the models in flood forecasting are trying to show. The analysis of the results shows that there is a consistency between different 2D models and that the reliability of the results strongly depends on the sufficiency of the available data.
