Abstract: Coastal zones are experiencing increased natural and human disruptions such as sea level rise, resource over-exploitation and coastal erosion. Waves, tides, winds, storms, sea level change, and human activities such as dams constructed upstream in rivers, all have an impact on coastal sedimentation and the geomorphologic processes of the shore. Satelliteborne coastline extraction and detection of change rates over time are used in coastal zone monitoring of these impacts. The present study focuses in Strymonikos Gulf (North Aegean, Greece) examining and assessing the coastline erosion “hotspots” using historic satellite images from Sentinel 2 sensor, wave data from an in-situ buoy and Copernicus wave products. The erosional processes were interrelated to the incident wave power and the propagating wave direction, in conjunction to the concentration of suspended particulate matter (SPM) in Strymon river plume.
