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...

Initial morphodynamic changes in the Voordelta in response to the Delta21 interventions

In recent years, the awareness of climate change and sea level rise has grown. Especially in low lying countries like the Netherlands, with a large river delta with a high economical and natural value, extreme variations in water levels will have great impact. Former used solutions proofed to be expensive and in some cases disturbed the dynamics...

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...

The effects of a continuous nourishment on the physical behavior of the Dutch coastline: Studying the behavior of a continuous nourishment at the Delfland coastal stretch in the first year of its lifetime

The growing awareness of climate change asks for innovation in the methods of applying nourishments at the Dutch coastline. The concept Zandwindmolen has therefore been developed. Using wind mills at sea, sediment is dredged offshore and transported towards the shore, from where hydrodynamic and morphodynamic processes redistribute sediment...

Modelling sediment sorting near the large scale nourishment 'The Sand Motor': Understanding cause and impact of sediment sorting processes

The sediment composition of the sea bed is of relevance for various coastal properties such as bed forms, beach slopes and marine ecology. Furthermore it may significantly influence the morphological evolution of the coast. Knowledge about the processes forcing the spatial distribution of a certain grain size is therefore of great importance....
