Description 53-64
Modeling transport, accumulation, and deposition areas of sediments are essential for assessing risks to coastal areas and the
environment. In this study, the advection-dispersion and accumulation areas of cohesive sediments entering the Black Sea from
Degirmendere Basin, the largest river basin on the Southeastern Black Sea coast, were modeled using the POMSED module, which
is a submodule of The Princeton Ocean Model (POM). The fate of cohesive sediments in the marine environment has been
predicted by different parameters, such as the change in the amount of cohesive sediment entering the Southeastern Black Sea, the
dominant surface circulation, the effect of the wind pattern, and the anticyclonic cycle. In the high-flow seasons, the sediment drift
velocity is also high. For large sediment drift velocity, cohesive sediments accumulate heavily in coastal areas east of the study area.
It has been determined that high sediment drift velocity is the most influential parameter in determining the accumulation areas of
cohesive sediments. In the low-flow seasons, the sediment drift velocity is also small. For small sediment drift velocity, cohesive
sediments accumulate at the river's mouth under the influence of the predominant wind. This study will constitute the basis for
coastal interventions to be carried out in the Southeastern Black Sea, port cleaning study plans, and risk assessment studies for areas
where fishermen's shelters are located.
