Coastal erosion is a process with widespread human impact. This well-written paper explains the NEWTS coastal erosion model in terms which will be accessible for geoscientists and beyond. It is recommended reading for anyone with an interest in this application area.
Short summary
Models of rocky coastal erosion help us understand the controls on coastal morphology and evolution. In this paper, we present a simplified model of coastline erosion driven by either uniform erosion where coastline erosion is constant or wave-driven erosion where coastline erosion is a function of the wave power. This model can be used to evaluate how coastline changes reflect climate, sea-level history, material properties, and the relative influence of different erosional processes.
