WSPEC – BAS Projesi

As the understanding of the nature of the sea state has evolved it became clear that in many occassion the sea state could not be defined by those spectral models representing a single wave system, and that it is necessary to describe sea states involving a combination of swell and wind waves, and even with multiple swell components. Within the scope of this project proposal, wave spectra in Black and Azov Seas will be classified for the first time in different spectral shapes. In addition, although the trend of significant wave height has been examined in the literature, the trend of peak energies will be examined for the first time with this project.

In order to reach these two important findings, the spectral wave climate of the Black and Azov Seas will be analyzed first. For this purpose, two different wave prediction models, WaveWatch III and SWAN, will be developed by Russian and Turkish teams respectively and the model results will be compared. The Russian team will prepare an unstructured grid system for use in wave models and develop, calibrate and verify the wave model for the Black and the Azov Seas with version 4.18 of the third generation spectral wave model WaveWatch III. The Turkish team will develop, calibrate and verify the wave model with the latest version of SWAN, SWAN 41.31. Classification of the obtained wave spectra will be carried out on the basis of the method described in studies of Bukhanovsky et al. (2005) and Boukhanovsky et al. (2007). The trend of peak energy will be realized by using the Şen’s Innovative Trend Analysis and Crossing Trend Analysis methods, which has been used in recent years as well as the Mann-Kendall analysis method which has been used most in the literature. Finally, Dolan and Davis (1992) scale will be used to characterize and classify wave storm events.

The project is expected to be completed in a total of 36 months. Total work package was determined as 14. Some of these work packages will be realized by the Turkish team and some by the Russian team, while approximately half will be realized jointly by the two teams.

Since the Turkish and Russian teams have extensive experience in modeling the waves in the Black Sea, it is anticipated that this joint cooperation project, prepared with a focus on a previously unexamined issue in the region, will provide significant gains in the two teams. The investigation of spectral wave climate is a work that involves the processing of large amounts of data and requires considerable effort. With the simultaneous operation of different teams and equipments, the process can be solved more easily and smoothly. It will be possible to calibrate the models according to measurements on both shores with the collaboration. With the proposal of this project, scientists who are experts in wave modeling in the Black Sea will be brought together and the results of the project will be published in highly prestigious international journals.

By means of the project proposal, the sea states, required for the design of offshore and coastal protection structures planned to be built on all Black and Azov Seas coasts and also for design and operation of ships used for increasing marine traffic in the region, will be revealed by wave spectra. In addition, an information repository to be used in determining suitable wave conversion systems in the region will be created. With the trend analysis to be applied to peak energy, anticipations can be formed which show the impact of global climate change on marine conditions.
