Publicatie type | rapport Deltares
The Ministry of Public Works is investigating the potential value of the proposed Ecobeach system, Pressure Equalizing Modules (PEM), under the framework of the WINN program (WAter INnovatiebron). To that end, a fieldexperiment has been carried out in Egmond aan Zee (The Netherlands), from November 2006 to December 2010. Two test areas (Jan van Speijk and Coast 3D) were selected where the Ecobeach modules were installed. Deltares was requested by the Waterdienst to assess the impact the PEM may have on the local morphological development. To that end, first a monitoring strategy for the field experiment in Egmond was set up, referred to as Phase I. In Phase II, a study approach was developed which formed the basis for annual data analysis studies. The present report describes the final data analysis and assessment of the effectiveness of the PEM based on the entire period (2007-2010).
