Extreme Wave Analysis Using Century Based Wave Climate Data

Abstract

Reliable and long-term wave data are essential for the design of almost all coastal and marine structures. In this study, the wave climate along the Turkish coasts was derived based on a century long data of European Centre for Medium-Range Weather Forecasts, CERA-20C. For this purpose, firstly, the data set was calibrated and verified by using the satellite and in-situ measurements. Then the design waves corresponding to various return periods were determined by extreme statistics. Therefore, a new and reliable design wave height data along the Turkish coasts have been provided for the designers and applicants. Results were compared with Wind and Deep Water Wave Atlas Along the Turkish Coasts (Ozhan and Abdalla, 2002). The comparison results indicate that the design wave heights provided by the Atlas are higher than the current study, especially in the Aegean Sea. © 14th MEDCOAST Congress on Coastal and Marine Sciences, Engineering, Management and Conservation, MEDCOAST 2019.
