Predicting the dune growth at a mega nourishment: By using a process based Integrated Hydro- Aeolian- Morphodynamic model.

The Sand Engine was constructed in 2011 with the main goal to enhance the natural dune growth. It is the first mega nourishment in the world comprising of 21.5 Mm³ of sediment. There is a large difference between the predictions of the dune growth (25 ha in 20 years) and the actual measurements (1 ha in 4 years). Therefore a more...
