In this study, circulation model of Büyük Menderes River and the adjacent coastal areas will

be presented. Büyük Menderes runs through the second biggest alluvial plains in Turkey and

discharges into the Aegean Sea where fishing and tourism are main income for the region.

Therefore, an accurate representation of water circulation is important both for the water

quality in the bay and the morphodynamics at the coast of Büyük Menderes Delta.

Finite Volume Coastal Ocean Model (FVCOM) is used for the circulation modelling mainly

because use of unstructured grid mesh enables modeling of a larger coastal water body with

higher resolution at river discharge region, efficiently. The model is set-up to assess the

patterns under the forcing of Coriolis, tide, wind, wave (SWAN integration) and river.

Results of model runs for March (rainy season) and October (dry season) 2017 will be

presented with comparisons to in situ data

(Figure 1). In situ data used in the model

includes salinity and temperature of sea

water and river, river discharge, wind

characteristics, water levels and current

measurements at three locations, which was

collected as part of a research project

campaign funded by The Scientific and

Technological Research Council of Turkey


These results are going to be used for calibration of the model and it is the first step of

developing regional circulation model for long term scenarios and future changes.
