Abstract

Gravel barrier beaches can offer natural protection to coastlines from adversestorm conditions. Understanding the morphodynamics of gravel barrier beachesis vital for the effective and sustainable management of these systems. Here, weuse a synthetic dataset to investigate the morphodynamic response...
