Abstract
The Southeastern Black Sea coastal region in Turkey and Georgia is under threat of severe coastal erosion and shoreline
recession. The main reason for this problem is the response of the coast to human activities. While water discharge rates were
reduced by dams by approximately 7% only, about 98% of the suspended sediment is being captured by the dams, leading to
reservoir siltation over time in the southern Black Sea Region Rivers in Turkey. About 83% of the total suspended sediments are
carried by the Coruh River to its mouth, which determines the characteristics of the river and the shape of the coastal region. In
this study, the effect of water runoff and sediment transport to the Black Sea Coast was investigated.
