Wave attenuation over the Oesterdam tidal flat nourishment: Wind-wave transformation in the intertidal zone

The Oesterdam tidal flat nourishment is a hook-shaped nourishment that was constructed in November 2013 in the Kom area of the Eastern Scheldt. One of the objectives of the nourishment is to increase the design life of the Oesterdam in the face of increasing wave loads due to structural erosion of the intertidal flats. A study is conducted in...

Decision alternatives for the safety of the Eastern Scheldt: Will it be cost-effective to remove the Eastern Scheldt storm surge barrier in case of sea level rise?

After the disastrous floods in 1953 in the Netherlands, measures are taken to improve the safety in the Netherlands. In the Southwest of the Netherlands a couple of tidal basins are closed by the construction of dams and storm surge barriers. The closure of tidal basins shortens the coastal length and can result in a cost reduction comparing...

Nourishing intertidal foreshore: Improving safety and nature

After extensive flooding in 1953, Deltaworks were constructed to protect the Southwest delta in the Netherlands. In the Eastern Scheldt the connection to the North Sea was regulated by an open storm surge barrier and two compartment dams. These decreased the tidal volume and consequently tidal flats are eroding and disappear under water. The...

Morphology of the Eastern Scheldt ebb tidal delta

The Eastern Scheldt tidal basin and its ebb tidal delta have changed drastically in the recent centuries under the influence of natural processes and human interventions. A Storm Surge Barrier, one of constructions within framework of Delta Project in the Eastern Scheldt, is considered as the largest impact to changes in hydrodynamics and...

Morphodynamic modelling of the Galgeplaat

Since the completion of the Eastern Scheldt project in 1987, in the south-western part of The Netherlands, there has been a decrease of tidal volume, range and current in the Eastern Scheldt estuary. This has led to morphologic changes in the basin. The channels are in demand of sediment and as the Eastern Scheldt barrier itself blocks most of...

Sediment transport through the Eastern Scheldt storm surge barrier

The aim of this research is to determine to what extend the scour holes limit the sediment transport through the Eastern Scheldt storm surge barrier and whether or not human adaptations, like sand-nourishments in the scour holes, can have a positive effect on the sediment import. To investigate these scenarios a numerical model (Delft3D) is used...
