Nourishment strategies for the Ameland Inlet

Sea level rise poses challenges to the tidal inlet systems of the Wadden Sea, including the barrier islands. If no measures are taken, the shorelines of the islands will retreat and the basins may drown. In the Ameland Inlet, the Boschplaat at the eastern tip of Ameland and Bornrif at the western tip of Terschelling are currently shrinking. <br/...

Global Assessment on the Lifetime of Mega Nourishments

Recently an innovative nourishment method has been applied as a counter measure for coastal recession in the Netherlands. This soft engineering solution, also known as the Sand Engine, consists of a shoreline perturbation of $21.5$ Mm\textsuperscript{3} sand which will be redistributed along the shore by the natural forces of waves, tides and...

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...

Morphodynamics of mega-nourishment: Integrated model approach for the design and management of mega-nourishment

In 2003, a first proposal for identification of seaward development, preliminary in combination with residential building, was presented in the Chamber of Deputies and within the States-Provincial (South-Holland), by respectively Geluk and Waterman. In response to this proposition, the ministry started an investigation, but concluded there was...

An intrinsic sediment tracing method using natural quartz- and feldspar luminescence

The goal of a sediment tracer is to give quantitative or relative feedback on (coastal) morphological changes or track either sediment or other particles (e.g. contaminations) in sediment dynamic environments. A sediment tracer is a visible or invisible marked (sediment) grain that is artificially injected or is present in-situ. This Master...

Evaluating the applicability of 2DH models for the prediction of mega nourishments: A case study of the Hondsbossche Dunes

In 2003 certain areas of the Dutch coast were found not to meet contemporary safety standards, as a result of erosion that occurred over the last century. One of these 'weak links' stretches from Camperduin to Petten and is known as the Hondsebossche Pettemer Zeewering; a former 'hard' sea dyke with a stone revetment. To fortify this 12...

Simulating dune growth at a mega nourishment

Initial morphological evolution of a mega nourishment: The Hondsbossche Dunes one year after construction

The coastal protection system of the Dutch low-lying hinterland is under increasing pressure due to growing population and high economic value combined with climate change and a rising sea level. Supplying sand to dunes, beach and shoreface by means of nourishments is a widely applied technique to increase coastal safety. Climate change and a...

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...

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...
