The hydrodynamics of an eco-innovative sediment reuse project in the Rotterdam Waterway: Gaining insight into the physics and the predictive capability of two operational hydrodynamic models

Phenomena like sea level rise, global warming and erosion together contribute to increasing flood risk in vulnerable coastal areas. As this flood risk increases, initiatives to mitigate the effects of climate change in the coastal zone are also increasingly sought. During recent years, the view that these measures should be circular has gained...

Morphological development of the Bollen van de Ooster: A potential hazard for Goeree-Overflakkee?

The Bollen van de Ooster, in this report referred to as the Ooster, is a sand bar in the outer delta of the Grevelingen. The Ooster is separated from the coast by a relatively deep channel, called the Schaar. Closure of the Grevelingen in 1971, with the construction of the Brouwersdam, initiated vast changes in morphology. Damming of the estuary...

Cross-shore morphodynamics of intertidal bars: A conceptual model, empirical evidence and numerical modelling

The beach recovery process determines the resilience of a sandy coast and is an important aspect of the coastal safety. Sediment stored underwater due to storms is transported onshore by the migration of subtidal and intertidal bars under mild wave conditions. The intertidal zone is an im-portant interface, connecting the marine and aeolian zone...

Marine and aeolian sediment transport at the Hondsbossche Dunes: Analysing and modelling the contribution of marine processes to beach and dune evolution

The Hondsbossche Dunes is a seven-kilometre-long dune, beach and shoreface nourishment that serves as a primary flood defence since 2015. In addition to its protective function, the Hondsbossche Dunes stimulate ecological habitat development in the coastal area, in line with Ecoshape's 'Building with Nature'-approach. Its morphologic development...

Identifying Windows of Opportunity for Mangrove Establishment on a Mud Coast: A case study for the BioManCo project in Demak, Indonesia

Assessment of the effects of nourishments on coastal state indicators, using a Bayesian modelling approach

The Dutch coast is affected by coastal erosion. In order to limit erosion and prevent inland migration of dunes, sand nourishments have been adopted as a common practice for the maintenance of the coast. The evaluation of the applied coastal erosion policy is achieved by the use of coastal indicators. Increased number of nourishments affects the...

The influence of sand mining on the coastal erosion of Ngapali, Myanmar

The beach at Ngapali, Myanmar is eroding, resulting in a shoreline which moves landward. The coastline gets closer to the vegetation each year and during the monsoon season, at high tide, it reaches the palm trees completely. The assumption is that this is due to people shovelling truckloads of sand from the beach to use for construction, this...

Global assessment of the potential effect of large sand replenishment on fresh groundwater resources

Sand replenishments, or nourishments, have been the prevalent strategy of the Netherlands for coastal protection since 1990. In consideration of the expected sea level rise and potential increases of storm surges as a result of climate change, an innovative pilot project known as the ‘Sand Engine’ has been implemented. In contrast with...
