Delft Hydraulics Testing Dune Revetments

The Dutch Directorate for Public Works and Water Management (Rijkswaterstaat) has commissioned WL Delft Hydraulics to investigate the behaviour of 'hard' elements (such as dune foot revetments or boulevards) in sandy dunes.

Since the dunes form a part of the Dutch primary water defence system, it is important to understand this behaviour. An example would be the effects of a collapsed dune foot revetment on dune erosion during super storm conditions.

A group of specialists from WL Delft Hydraulics, assisted by specialists from other institutes (University of Delft and Alkyon) carries out these investigations.

Large scale dune erosion tests in the Delta flume of WL Delft Hydraulics will play an important role in the project to provide guidance to coastal administrators responsible for the Dutch dunes.
