摘要

The town of Akyaka, located in the northeast of Gokova Bay at the Southern Egean Sea coastline of Turkey, has a sandy beach lying in the north-south direction that has been significantly eroded. Two coastal structures, a breakwater and a groin, both constructed just at the mouths of two fresh water creeks are the main causes of shoreline change in the region, affecting the coastal sediment dynamics. About 60 meters of erosion has been observed between these structures when the present coastline is compared with the coastline in 1945. Being an important recreational destination in the Gokova Specially Protected Area, it is quite essential to stop the coastal erosion problem and to regain the eroded beach for Akyaka. Therefore, in order to understand and identify the coastal dynamic processes and sediment transport characteristics of the region, and thus, the reasons for the beach erosion, a research project, entitled as "Determination of Sediment Transport Rate and Shoreline Changes on Akyaka Coast" and financially supported by The Scientific and Technical Research Council of Turkey, TUBITAK, was carried out. For an accurate prediction of sediment transport in a region, as the first step, the wave and current hydrodynamics of the coastal area should be well understood. Therefore, in the mentioned research project, first of all, long-term wind and wave climate and wind induced currents and circulation patterns were studied in the region. Wind and wave statistics were obtained from the wind measurements of Turkish State Meteorological Service at Bodrum meteorological station between the years 1970 and 2011, and the wave characteristics predicted by CEM method for the same period. The current patterns were numerically modelled by three-dimensional baroclinic model, HYDROTAM-3D, which consists of hydrodynamic, transport and turbulence model components. Results of this study have been an important input to understand the coastal sediment dynamics of the region.
