Özet:

In this study; coastal circulation of Buyuk Menders river mouth and the adjacent coastal areas is modeled to determine the current characteristics of the region under river-sea interaction. For this purpose, Finite Volume Coastal Ocean Model (FVCOM) numerical model is setup and run under wind, tide, and river forcing conditions. Current, salinity, temperature data from field measurements are used to validate the performance of the model setup with default parametrization. Significance of each forcing on the overall current system is assessed by modeling each forcing independently and comparing these results with the current measurements. It is seen that tidal forcing has the lowest contribution, as the area is microtidal. Wind and river contributes much significantly however the river effect is seen in the closer regions and under higher river discharge conditions whereas contribution of wind is observed all over the area but with a lag in time. As the default model setup performed satisfactorily, 09 - 20 January – 2016 event that represent maximum river flow, maximum wind speed extreme forcing event is also modeled. As hydrodynamics of river mouths is very complex, longer measurement datasets both for the coastal area and the river characteristics is required to improve the performance of these models.
