Risk assessment of coastal erosion of Karasu coast in Black Sea

Coastal erosion occurs as a result of human ac tivity and natural phenomena. Coastal erosion causes significant economic and ecological problem. There is continuing serious coastal erosion along the Karasu coastline. This study reports on the process of determining the extent of the coastal erosion using satellite images from different time periods and the analysis of the risk to the environment. The change in the coastline over a 26-year period from 1987 to 2013 was determined using satellite images. In this study, significant coastline movements were detected for a 26-year period. For this study, the Karasu coastline was subdivided into 7 sections for analyses the coastal erosion risk. The risk of each section can be determined by using the classic risk. The results showed that both sides of the river outfall and the coastline have a moderate risk level with the area of the breakwater has a low risk.
