Abstract
Remote sensing and satellite imagery have become commonplace in efforts to monitor and model various biological and physical characteristics of the Earth. The land/water interface is a continually evolving landscape of high scientific and societal interest, making the mapping and monitoring thereof particularly important. This paper aims at describing a new automated method of shoreline position detection through the utilization of Synthetic Aperture Radar (SAR) images derived from European Space Agency satellites, specifically the operational SENTINEL Series. The resultant delineated shorelines are validated against those derived from video monitoring systems and in situ monitoring; a mean distance of 1 and a maximum of 3.5 pixels is found.
Highlights
Coastal areas represent complex and highly dynamic environmental systems continuously facing undergoing changes due to natural as well as anthropogenic factors
To support decision-makers and policy with a management tool for coastal zones defense, this study proposes a new methodology for shoreline detection using Copernicus

Summary
Coastal areas represent complex and highly dynamic environmental systems continuously facing undergoing changes due to natural as well as anthropogenic factors. The monitoring of their evolution is crucial for the safeguarding thereof. Sea hazards and extreme storm surges are increasingly threatening coastal areas causing among others flooding, coastal erosion, and damages to ecosystems and infrastructures [3]. Urban pressure, shifting land use, and variations in dunes and sea bed stability [4,5,6] have and are contributing to a further exacerbation of these hazards. Many coasts throughout Europe, and in the Mediterranean [7], are expected to experience increased flooding in response to current coastal and dune management strategies
