A numerical assessment of land reclamation as a strategy for nearshore diamond mining

On the south-west coast of Namibia, diamonds were trapped during the Quaternary on bedrock platforms and in bedrock gullies. These were formed by differential erosion due to wave action. The diamonds originated from Kimberlite diamond pipes within the catchment area of the Orange River in South-Africa and Botswana. This river eroded the diamonds...

A method to calculate the probability of dike failure due to wave overtopping, including the infragravity waves and morphological changes

In this thesis, a method was developed, with which the infragravity waves and morphological changes of a sandy foreshore are included in the calculation of the probability of dike failure due to wave overtopping. Constructing a natural foreshore in front of the dike can be an attractive and innovative method to decrease the failure probability....

Predicting Coastal Hazards with a Bayesian Network

Recent and historic events have demonstrated the European vulnerability to coastal floods. Larger and more extreme events in Asia and the Americas have shown the devastating effects that these low-frequency high-impact floods can have. This thesis contributes to the development of an Early Warning System (EWS) for marine coastal hazards. The...

Incident, infragravity and very low frequency wave motions on an atoll reef platform

Coral reefs are hard structures that front many coasts in tropical and subtropical climates and protect them against wave attack and erosion. Despite reducing incoming wave energy by up to 98%, coral reefs are not a guarantee that mainland or island coasts are safe from being flooded. This was demonstrated by a series of wave-driven flooding...

An assessment on hydro- and morphodynamic proceses at the sand motor during the Decemberstorm of 2013

In 2011 the Sand Motor was realised at the coast of the province of South-Holland as a pilot project combining different functions such as safety, recreation and nature development, following the philosophy of Building with Nature. The idea was to create a mega nourishment that would supply the coastal system between Hook of Holland and...

Wave runup on atoll reefs

The aim of this research was to take the first step in understanding the wave runup process on an atoll reef using the XBeach model. Field data collected from 3 November 2013 to 13 April 2014 at Kwajalein Atoll in the Republic of the Marshall Islands was used. The dataset included data on bathymetry, waves, water levels and wave-induced runup....
