Item A COMPARATIVE STUDY ON THE WAVE CLIMATE OF SOUTHERN AEGEAN COASTLINE OF TURKEY(2022-02-15) Al-Sammarraie, Khalooq Ahmed Alauldeen; Numanoglu Genç, Aslı; Balas, LaleIn this thesis, the wind and wave climate of southern Aegean Sea coastline of Turkey are studied. Six coastal areas to the South of İzmir Bay are selected for the analysis, namely as Kuşadası, Yalıkavak, Turgutreis, Marmaris, Fethiye and Datça coastal areas. In the wind climate analysis, the over land measurements of General Directoriate of Meteorology (GDM) are compared with the over sea wind estimates of European Centre for Medium-Range Weather Forecasts (ECMWF) operational archive. Additionally, the monthly maximum values of wind speeds are compared with the short-term over sea measurements of GDM. It is concluded that ECMWF over sea wind estimates present the wind conditions better than the over land and over sea wind measurements of GDM. In the wave climate analysis two methods are utilized. First, CEM empirical method is used to estimate the wave heights for the wave climate analysis. ECMWF wind predictions are selected in the CEM method. Secondly, the wave results of WAM numerical model are used for the wave climate analysis directly. In the wave climate the long term and extreme value statistics are studied. The significant wave height results of two methods from the long-term wave statistics are compared by studying nearshore and offshore locations for each coastal area. It is concluded that, for the nearshore part, WAM model gives lower wave heights than the CEM method. For the offshore part, WAM Model gives higher wave heights than the CEM Method, if the fetch lengths are relatively short. For the enclosed basins, it is seen that WAM model under estimates the wave heights, and therefore it is concluded that CEM Method gives more reliable results.
