Two model innovations were developed. Firstly, a behavioural model was developed to predict berm growth during calm conditions, as well as erosion during episodic storm conditions. A second innovation calculates a re-distribution of the sediment transport in the upper swash zone, to account for incident band swash-induced sediment transport, which is not resolved in XBeach Surfbeat, but is of major importance, especially on reflective beaches. The model successfully predicts the behaviour of the beach throughout the recovery period, and shows good potential for long-term simulations.
