Antalya Bay is located in the Mediterranean Sea of Turkish coasts. City of Antalya is one of the major tourism cities of Turkey with an increasing population. The sea outfall was constructed in the Antalya Bay. In this study, the currents and wind have been observed and measured. The wave height distribution, current pattern and concentration have been presented. Wind driven currents have been numerically modeled with the HYDROTAM3 which is a powerfull tool to simulate hydrodynamics of a coastal area. The bacterial pollution distribution due to the sea outfall of Antalya city was numerically modeled.
