To explain the development and patterns of the boundary layer that develops around the structure when a structure is exposed to wave/current effects; to provide an understanding of the secondary flow structures that may occur around the coastal structure during the wave/current structure interaction process; to understand the development of the boundary layer near the bottom and the hydrodynamic effects on the structure in the coastal zone, to understand the role of object geometry and wave/current characteristics on these effects; to explain the scour dynamics around the structure by activating the secondary flow structures formed near the foundation and their mobile foundation material; to teach the precautions to be taken against scour problems.

The course explains the external forces acting on coastal structures in the current and wave environment. The development and separation of the boundary layer around the structure and on the seabed play an important role in determining the dynamic effects acting on the structure and the seabed, often with a periodic component. The erosive effect on the seabed as a result of the combined action of the structure geometry, the characteristics of the seabed material and the current/wave conditions will be considered in detail during the course. In this context, possible scour/deposition processes around coastal and marine structures (such as sea walls, individual piles and groups of piles, caisson breakwaters, masonry breakwaters, pipelines) and measures that can be taken against scour are discussed.
