Vargas Solis, A. (author)
The response of longshore sediment transport to the morphodynamic state of the beach was assessed with the use of the process based numerical model, Delft 3D. For this purpose, idealized simulation bathymetries that reflect morphological characteristics of two different beach states (namely longshore bar and trough and transverse bar and rip)...

Due to growing human activity in coastal zones, there is an increasing stress on salt marshes all over the world. These intertidal wetlands were often seen as coastal ‘wasteland’ and large areas were reclaimed for urban development and agriculture. In Puget Sound, a system of interconnected marine waterways and basins in the northwest of the...

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...

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...

Een onderzoek naar de morfologische veranderingen in het Friesche Zeegat. Na de afsluiting van de Lauwerszee is het bekken continu in verandering. Dit heeft gevolgen voor de bevaarbaarheid van de vaarroute naar Schiermonnikoog. In dit onderzoek wordt een voorspelling gedaan naar de ontwikkelingen voor het komend decennium en de gevolgen van deze...

In this study, a process-based, depth-averaged Delft3D hydrodynamic and morphologic model of the Wax Lake Delta in Atchafalaya Bay, Louisiana was developed to simulate a five year period of delta development. The purpose of this modeling effort was to test the ability of process-based modeling tools to successfully simulate typical delta...

The wetlands in the Mississippi delta (USA) are drastically subsiding and eroding. Many projects and researches are ongoing to determine how this “drowning effect” of the delta can be stopped. One of the solutions that could be feasible is implementing sediment diversions in the levees of the Lower Mississippi River in order to divert sediment...

The Dutch Wadden Sea is consisting of 7 tidal inlet systems separated by sandy barrier islands. The general morphodynamics and hydrodynamics of tidal inlets are relatively well understood, but the detailed interactions remain a prominent research interest. In this study, process-based computer models are employed as a tool to investigate the...

Schlooz, G. (author)
This study investigates the hydrodynamics at a convex coastline. The Sand Engine, a man made peninsula in the Netherlands, is used as a case scenario. It is hypothesized that a rip current can develop under certain wave conditions due to the change in coastline orientation. The main goal of this research is to obtain a better understanding of...

The Langmann reservoir is part of the hydropower system in the river Teigitsch and in the reservoir loss of storage volume occurs. The reservoir was therefore flushed, but recently no permission is granted. The reason is the high sediment concentrations that have negative effects on the downstream region. An optimization of the flushing...

By its very nature dredging is an environmental impact, since dredging includes the excavation and/or relocation of sediment in a river, sea or estuary. One of the environmental impacts related to dredging is increased suspended sediment concentration (SSC) levels, forming plumes of sediment. These so called dredge plumes originate from spillage...

Scheel, F. (author)
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...

Hasselaar, R.W. (author)
The numerical flow model Delft3D simulates the flow of water and movement of submerged sediment by means of solving simplified equations that describe these processes. Because of these simplifications, parameterizations are introduced. These parameters represent amongst others the processes that take place on scales smaller than the spacing of...

Hoogduin, L. (author)
The aim of this research is to determine to what extend the scour holes limit the sediment transport through the Eastern Scheldt storm surge barrier and whether or not human adaptations, like sand-nourishments in the scour holes, can have a positive effect on the sediment import. To investigate these scenarios a numerical model (Delft3D) is used...

Arailopoulos, I. (author)
Depth-averaged morphological computations using Delft3D tend to produce ‘strange’, results for river bends when the sediment transport formulas of Van Rijn are used. Even pools in inner bend regions and bars in outer bend regions can result from the model. The objective of the present thesis is to identify the cause of the problem and propose...

Commandeur, A.S. (author)
Turbidity currents are major transport agents in reservoirs in which high concentrations of fine sediments flow in. Reservoir sedimentation due to turbidity currents is often severe in these cases. Turbidity currents are not well understood due to their complex turbulent flow structure, the interaction between the flow with the particles and the...

Maasvlakte 2 is het project waarmee de haven van Rotterdam wordt uitgebreid. Het sluit direct aan op de huidige Maasvlakte. De havenbekkens van beide Maasvlaktes worden verbonden door de Yangtzehaven in westelijke richting door te steken naar Maasvlakte 2. De doorsteek bestaat uit een voorfase waarin een kanaal wordt gegraven ten behoeve van de...

Problem definition The city Mar del Plata has one of Argentina's largest ports and biggest seaside beach resort. After the construction of the port, a steadily growing sandbank appeared in the port entrance and considerable erosion occurred on the northern beaches. To warrant the accessibility of the port, frequent maintenance dredging is needed...

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...
