Abstract

A process-based numerical model has been used to explore the sensitivity of equilibrium recession rates () and equilibrium profiles of eroding soft rock shores to a range of sea-level rise rates. Shore erosion was simulated under ranges of wave height and period, tidal amplitude, rock strength, beach volume and rate of sea-level rise. Equilibrium recession rates were found to be insensitive to beach volumes less than approximately 20 m3/m. Equilibrium shore profiles were dependent on the rate of sea-level rise. A simple expression was found to describe the relationship between future and historic rates of sea-level rise and equilibrium recession for shores with a low beach volume.
