Morphodynamic models are important for predicting the impact of sandy interventions on coastal safety and the environment. The Sand Engine project in the Netherlands aims to increase dune area naturally by incorporating aeolian sediment transport. To accurately model this, a new model combining morphodynamics and aeolian sediment transport is needed. Current models only focus on either hydrodynamics or aeolian sediment transport, but not both. Recent advancements in model couplings now allow for the interaction between these processes to be implemented.
