Integrated modelling of the morphological evolution of the sand engine mega-nourishment

This study presents some recent developments in coastal morphological modeling focusing on flexible meshes, flexible coupling between models operating at different time scales, and a recently developed morphodynamic model for the intertidal and dry beach. This integrated modeling approach is applied to the Sand Engine mega nourishment in The...

Numerical modelling of erosion rates, life span and maintenance volumes of mega nourishments

Mega-nourishments, aiming at providing long-term coastal safety, nature qualities and recreational space, have been applied recently at the Holland coast and are considered at various other places in the world. Methods to quickly evaluate the potential and lifetime of these coastal mega nourishments are therefore very much desired, which is...

Assessment of the variables influencing sediment transport at the Sand Motor

The objective of this thesis is to investigate the role of different hydrodynamic and morphological factors influencing sediment transport patterns at the Sand Motor in order to give insight in processes controlling the short-term sand bar morphodynamics and the long term development of the Sand Motor. The work presents an analysis of the...

The influence of a tidal inlet system on a nearby mega-feeder nourishment

All over the world coastal communities are at risk due to sea-level rise and intensifying weather conditions. Many sandy beaches are eroding as a result of human-induced factors. Currently, the preferred coastal protection measure in the United States are beach nourishments. In Europe, there also is a general shift from hard to soft coastal...

Investigation of Morphological Changes along the South West Texel Coastline and the Initial Response of a Mega Nourishment

In 1990 the Dutch government passed legislation that dictates the South West Texel coast must be maintained with regard to the 1990 coastline. The coast is currently maintained by applying shoreface and beach nourishments with an interval of approximately 3 years, because it experiences erosion. The problems with this approach are that the...
