The
problem of shoaling on coastal structures is the result of an event that occurs
as part of the natural cycle. In cases where shoaling cannot be detected or
prevented, various economic and operational problems may arise and may cause
disruptions. In this study, the complex coastal dynamic impact of shoaling on
three sequential fishery coastal structures located within the borders of Rize
province in the Eastern Black Sea region of Türkiye was examined in terms of
bathymetric changes and sediment transport under the influence of the incident
wave climate. The effects of these structures on each other were also
investigated. With this aim, bathymetric measurements were carried out to
examine the impact of waves on seabed erosion and deposition. A serious
shoaling problem was identified at one of the harbor launches under
investigation, where approximately 13,200 m3 of deposition occurs annually in a relatively small
harbor launch area. Such physical problems are thought to be the result of
shoaling, the selection of sites that are not viable for fishery-related coastal
structures, or the wrong positioning of the breakwater.
