In dit onderzoek is aandacht besteed aan de gravitatie circulatie in de Waddenzee. Daarbij is de vraag of dit een rol kan spelen bij sedimenttransport. De gravitatie circulatie is een stroming die bovenin de waterkolom een andere stromingsrichting kent dan onderin en ontstaat doordat het water niet een uniforme dichtheid kent in het bekken....

Several programs have been written to process laser scan data from two shoals in the Netherlands. The first makes a grid of heights, the second calculates deformations and makes plots. The third utilises a variogram to obtain information about the amplitude, direction and wavelength of tidal ripples, which are processed and plotted by a fourth...

The objective of this study is to identify the mechanisms that drive the morphodynamic behaviour of the sediment disposals in the subtidal zone north of the intertidal shoal Walsoorden. The morphological development of the sediment in the subtidal zone near this shoal has been monitored and measured. The gathered bathymetric data show that one...

Extracellular Polymeric Substance is found to be responsible for the stabilizing behaviour of biofilms on sediment, but studies disagree on how this stabilizing effect is achieved and what processes are involved in making an EPS biofilm shear off. This study answers the question how the biofilms achieve the stabilizing effect and what processes...

Tidal inlet systems, as found in the Dutch Wadden Sea, often feature both sand and mud. Due to differences in sediment properties, sand and mud particles respond different to identical forcing conditions, like short waves and tidal currents. Because of this, sand and mud can get transported to different locations. This process is referred to by...

In opdracht van het Recreatieschap Westfriesland werd een onderzoek gestart naar het verzandingsprobleem in de vluchthaven Wijdenes. De vluchthaven kampte jarenlang met verzandingsproblemen en er zijn diverse onderzoeken en aanpassingen uitgevoerd, maar het probleem is nog steeds niet verholpen. Door de verscherpte wetgeving in 2008, zijn de...

The area of New Orleans was hit by Hurricane Katrina in August 2005. A large part of the city got flooded due to bad design, construction and maintenance of the levee system. In order to increase the level of protection of the city, the levees are heightened and strengthened in the framework of the Hurricane and Storm Damage and Risk Reduction...

In the last century, various tidal rivers in Europe have seen a large tidal amplication, which is believed to be caused by the deepening and channelization of these rivers. Additionally, large increases in suspended sediment concentrations induced by flood dominance are thought to have decreased the effective hydraulic drag, enhancing further...

After the storm surge of 1953, the Dutch Delta project was initiated in order to protect the southwestern part of The Netherlands. A storm surge barrier in front of the Oosterschelde and various dams at the back of the estuary were constructed. These interventions led to a large change of the hydrodynamics of the Oosterschelde: a large decrease...

Little research was done in the past concerning the propagation of three dimensional effect in shallow wake flow caused by a roughness patch. Today’s research on related subjects is dominated by emerging obstructions in shallow water where the flow can be assumed as (quasi) two dimensional. However the relevance of a submerged obstruction with...

In this thesis the position of tidal divides is studied by means of a simplified model and the Dutch Wadden Sea. To study the parameters influencing the location of the tidal divide, two basins are schematized to a rectangular channel with at each side an incoming tidal wave. These two incoming waves can differ in amplitude and have phase...

Groynes are commonly used in the major rivers in the Netherlands. They confine the flow of the river to a main channel but also act as resistance element once submerged and in that way influence the stage discharge relationship of the river. Several formulas exist describing groynes as a drag resistance. Another possible way of determining their...

Coral reefs are highly diverse ecosystems that provide food, income, and coastal protection for hundreds of millions of coastal dwellers. They are found in tropical and semi tropical areas spread throughout South-east Asia, the Caribbean, the Indonesian archipelago, on Australian coasts and in the Pacific islands. Coral reefs are subject to both...

The tide-dominated Scheldt estuary is located in the southwest of the Netherlands. From the Dutch-Belgian border seawards, it consists of a system of channels and shoals and an ebb-tidal delta facing the North Sea. The behaviour of non-cohesive (sand) and cohesive (mud) sediment particles in the area are (until now) generally studied using...

To counteract relative sea level rise, Rijkswaterstaat nourishes the Dutch coast with sand. This sand spreads out over the shoreface zone, beach and dunes. One of the nourishment types is the shoreface nourishment. In this thesis, data of historical shoreface nourishments along the Dutch coast is analysed to find the factors that influence this...

De ecologische kwaliteit van het Markermeer is de laatste decennia sterk achteruit gegaan. De oorzaak hiervan is dat door de afsluiting van het Markermeer met de Houtribdijk een ondiep meer is ontstaan met een bodem van klei waarin een dynamische sliblaag aanwezig is. Al bij lage windsnelheden ontstaan golven die erosie van deze sliblaag...

The fairway connecting Holwerd and Nes forms the main transport route between Friesland and Ameland (the Dutch Wadden Sea). It consists of several tidal channels that funnel the majority of the tidal currents propagating through the tidal basin. Over the past decades, several channel bends have expanded leading to a fairway length-increase of...

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...
