Subaqueous and Subaerial Beach Changes after Implementation of a Mega Nourishment in Front of a Sea Dike

Sandy nourishments can provide additional sediment to the coastal system to maintain its recreational or safety function under rising sea levels. These nourishments can be implemented at sandy beach systems, but can also be used to reinforce gray coastal infrastructure (e.g., dams, dikes, seawalls). The Hondsbossche Dunes project is a combined...

The effects of beach house configurations on dune-ward sediment transport

In the Netherlands, the coastal dunes are essential to protect the country against flooding. However, the rising sea levels increase the risk of flooding along these sandy shores. Moreover, due to a combination of human and natural activities, dune erosion has increased and will continue to do so in the coming decades. Besides flood protection,...

The effects of climate change on coastal management in the Hondsbossche Dunes: Analysis and modeling of aeolian sediment transport and dune growth

In 2003, it was established that the sea dike between Petten and Camperduin was insufficiently safe.<br/>To ensure the safety of the hinterland against flooding, this part of the Dutch sea defence system needed to be strengthened.<br/>During the design process, the most favourable variant was to construct a dune and beach system in front of the...

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...
