A Mega-Nourishment (Sand Motor) Affects Landscape Diversity of Subtidal Benthic Fauna

The Sand Motor is a very large (20 million m³) nourishment constructed along the coast in The Netherlands. The huge volume of sand is redistributed along the coast by natural forces stemming from tidal currents and waves. For environmental evaluation of this large construction, the benthic subtidal fauna has been sampled prior to...

Effect of Different Forcing Processes on the Longshore Sediment Transport at the Sand Motor, The Netherlands

The Sand Motor is a pilot project of a ‘mega-nourishment’ built in the Dutch coast in 2011. In order to understand which conditions reshape those mega-nourishments the influence of different types of forcing on the longshore sediment transport along the Sand Motor has been assessed in this paper using a process-based model. The use of numerical...

The sand engine: A solution for the Dutch Delta in the 21st century?

The Netherlands’ strategy to combat coastal erosion since 1990 has been through nourishment, initially as beach nourishments but more and more as shoreface nourishments. In the light of sea level rise projections the yearly nourishment magnitudes continue to increase. In view of this an innovative soft engineering intervention, comprising an...

The sand engine: A solution for vulnerable deltas in the 21st century?

The Netherlands’ strategy to combat coastal erosion since 1990 has been through nourishment, initially as beach nourishments but more and more as shoreface nourishments. In the light of sea level rise projections the yearly nourishment magnitudes continue to increase. In view of this an innovative soft engineering intervention, comprising an...

Coastal Erosion and Solutions: A primer

This primer describes some of the causes of coastal erosion and tries to put into perspective their scale and consequences. There are no uniform causes, just as there are no uniform solutions. Erosion tends to be site-specific. Yet, with careful observation and measurement, a particular problem can be placed in context and draw from the...

Effectiviteit van vooroeversuppleties langs de waddenkust: Aanzet tot ontwerprichtlijnen voor het ontwerp van vooroeversuppleties

In dit rapport wordt verslag gedaan van een eerste evaluatie van zes vooroeversuppleties, namelijk die van Callantsoog-2001, Molengat -2003, De Koog- 2002,Vlieland-2002, Terschelling-1993 en Ameland-1998. De evaluatie betrof het analyseren van de beschikbare dieptegegevens en het op basis daarvan vaststellen van de belangrijkste effecten van de...

Nearshore Bathymetry derived from Video Imagery

Owing to the economic importance of seasonal fluctuations in beach width and the frequent implementation of local beach and shoreface nourishments, coastal managers and scientists increasingly demand coastal state information at smaller spatiotemporal scales. Advanced, automated video techniques provide the means to collect such high-resolution...

Beach Nourishment: Design Principles

Design principles for beach nourishment in the form of cross-shore response, planform evolution of beach nourishment projects and damage reduction

Beach Nourishment

An analysis of "soft" measurements, in the form of beach nourishment, to protect ourselves against the sea. The rapport covers the following subject with regard to "soft" measurements: - Design of soft solution: review of design tools, practical consequences of morphological theory and failure modes - Construction methods for soft solutions:...
