Attema, Y.H. (author)
The interaction between vegetation and the morphodynamics is considered to be an important process in salt marsh formation and succession. Therefore, the contribution of vegetation modelling on the long-term morphological development of salt marshes is assessed by implementing a vegetation growth model in the morphodynamic modelling software...

Recently an unstructured version of Delft3D, named D-Flow FM, has been developed at Deltares. This tool shows high potentials for coastal modelling due to the flexibility in domain resolution and unstructured grids. This MSc thesis focussed on implementing wave effects in D-Flow FM with satisfying results. In addition, a coupling system is built...

Artificial beach and foreshore nourishments, as executed widely along the Dutch coast, change the nearshore morphology and current patterns significantly. Over the last decades the size of the nourishments has increased from 0.7 x 106 m3/km to over 6 x 106 m3/km. Groynes which were present along the southern Holland coast since the 19th century...

A large number of beach morphologies across the world exhibits nearshore sandbars with complex 3D patterns. During large storms, these shapes disappear and the bars get to a certain extent alongshore uniform. This phenomenon is called a reset. Numerous studies have been conducted on the development of the bar shapes (3D) or on the cross-shore...

This thesis presents the application of an aeolian transport model used in desert environments [Sauermann et al., 2001, Kroy et al., 2002] as a tool for the evolution of coastal nourishments. This study will try to investigate the driving processes in the model and adapt or extend the model application to the coastal system. If we want to apply...

It has been found by many researchers that low frequency (LF) waves dominate the wave energy spectrum in very shallow water. Given that many longshore and cross-shore morphological processes are located within this zone, LF waves play an important role in determining morphological change, especially dune erosion and overwash during storm events....

The reshaping of temporary rubble mounds like the core of breakwaters or reclamation bunds is often a concern for contractorsi n the construction stages of marine structures. The formulas found in literature for the prediction of such behavior are few, and they do not provide clear insight on the influence of relevant parameters, in particular...

This thesis is an exploratory research into the maintenance of the Slijkgat, by analysing the morphological behaviour of the Slijkgat and the Haringvliet. The Slijkgat is the approach channel for the fishery harbour of Stellendam. The delta area west of the Haringvliet Dam started to accrete after the construction of the dam around 1970,...

The primary objective of this thesis is to generate a 2DH-numerical model to simulate dune overwash. The first stage in this is achieved by modifying the program code of an existing overwash model in development, XBeach, to enable 2DH calculations. In the second stage the hydrodynamics of the model are verified using theoretical and laboratory...

Model simulations on the basis of uniform (non-graded) sediment reveal a strong overestimation of the scour hole in the area directly to west of Maasvlakte I when compared to the measured scour hole. Data analysis shows that the scour hole developed in a former complex estuarine system. The analysis strongly suggests that erosion occurred...

Collection of long-term data sets of wave characteristics and bathymetry with high resolution in time is a prerequisite to improve our understanding of nearshore coastal dynamics. Advanced video monitoring systems allow to sample these data automatically, on a long-term basis and without the need to deploy in situ instruments in a hostile...

The data content of remote sensing (RS) images of sea surface temperature (SST) and normalized water-leaving radiance (nLw), for the year 1998, with respect to the River Rhine plume, is investigated. Questions that this study tries to answer are: is it possible to identify the plume from the available RS images, and under which conditions is...

When a river discharges into the sea it forms a river plume. The main property of these plumes is their buoyancy; fresh water discharged by rivers is less dense than the receiving, saline waters. Due to the rotation of the Earth, these plumes tend to turn to the right in the Northern Hemisphere after entering the sea. Previous studies...

This thesis describes a numerical study on identifying parameters controlling the shoaling rate for the normally incident low frequency motion and the long wave reflection in the coastal zone.

Het zoeken naar een geschikte locatie voor een nieuw aan te leggen vliegveld heeft in Nederland al tot vele studies geleid. Een van de altrnatieve locaties voor het huidige Schiphol is een nog aan te leggen eiland in de Noordzee en wordt 'Schiphol in zee' genoemd. Bij grootschalige landaanwinning in open zee worden twee verschillende types...

This master thesis project focusses on the numerical modelling of bound and free long wave action in two diffrent harbours. This model, called Surf Beat, is a time dependent generic numerical model for the simulation of generation and propagation of bound long wave energy generated by short carrier waves. This model has been developed by Delft...

Strandhoofden zijn lange smalle dammen die langs de kust worden aangelegd om structurele erosie te bestrijden. Door hun lengte onderbreken ze het natuurlijke transport van zand langs de kust geheel of gedeeltelijk. Voor het ontwerp van strandhoofden is met name de lengte en de onderlinge afstand van belang. Het is echter moeilijk om vooraf in te...

The shoreline develops on several time scales. At some places along the coast the amount of sand in a cross-section decreases continuously and the shoreline shifts landward. This phenomenon is called structural erosion and is often caused by an increasing longshore sediment transport along the coast. When it is necessary to protect the coast, e...
