Erosion of gravel beaches and barriers

The erosional behaviour of gravel type beaches and barriers has been studied using a parametric and a process-based model. Both models have been applied to large-scale laboratory experiments and to a field case at Pevensey Bay, UK. Both models show suprisingly good agreement for realistic wave conditions. The process-based model has been used to compose a graph of gravel beach erosion as a function of storm surge level and gravel size.
