Modelling coastline maintenance : a review of three coastline models

Coastal evolution models have been used in the past to assess nourishment volumes for the Zwakke Schakels projects on the Dutch coast. The results of these simulations showed substantial differences in required nourishment volumes for the affected coasts. This report focusses on identifying differences between three coastal evolution models (UNIBEST-CL+, PONTOS and LONGMOR) and the effect these differences have on model predictions of coastal evolution and nourishment volumes.
