Abstract
This study investigates the erodibility against wave overtopping of clay and grass using vertical forces acting upon a turf-element model. The load is modelled by a lift force caused by pressure fluctuations and the strength by the self-weight, cohesion, shear and root forces. Besides the proposed turf-element model, a failure model for grass based on scour equations has also been developed.
