In many tidal embayments, bottom patterns, such as the channel-shoal systems of the Wadden Sea, are observed. To gain understanding of the mechanisms that result in these bottom patterns, an idealized model is developed and analyzed for short tidal embayments. In this model, the water motion is described by the depth- and width-averaged shallow...

The study focuses on the impact of human interventions on the natural behaviour of estuaries in response to sea-level rise. In particular it focuses on the affect of managed realignment on the critical sea level rise (SLRcrit) for the Poole Harbour. Numerical model ASMITA (Aggregated Scale Morphological Interaction between a Tidal inlet and the...

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...

The objective of this thesis is to improve the insight into the morphological processes in the outer delta of the Westerschelde estuary, especially those related to the sediment exchange between the delta and the estuary. The main residual sediment transport patterns in the delta have been found to look as follows. On a large scale there is a...

The objective of this study is to develop a methodology for hybrid modelling of sedimentation in a coastal basin or large shallow lake where physically based and data driven approaches are combined. This research was broken down into three blocks. The first block explores the possibility of approximating a physically based model using a data...

By changing flow patterns and sediment transport, aquatic vegetation can affect the development of estuarine bed topography. Besides, since the sediment transport also determines the amount of light available for photosynthetic growth, the presence of vegetation can also affect its own development. This selfsupporting interaction should be taken...

In this thesis, the particle model that takes into account the short term correlation behaviour of pollutants dispersion has been developed. An efficient particle model for sediment transport has been developed. We have modified the existing particle model by adding extra equations for the suspension using a probabilistic concepts (the Poisson...

The Dutch Western Wadden Sea, comprising the basins of Texel, Eierlandse Gat and Vlie, suffers a shortage of sediments. This implies that sediment is imported into the basins. The influence of the main forcing agents on the sediment transport is investigated. These forcing agents are the tide, waves and wind. In case of the wind forcing, both...

The initial growth of bed perturbations on planar sloping beaches under the forcing of obliquely incident, breaking waves is investigated using a state?of?the?art numerical model. This allows for a systematic investigation of the sensitivity of the spatial structures of the bed perturbations and their growth and migration rates to different...

Hydraulic characteristics of flow in a tidal inlet act an important role in morphological changes of the inlet. In normal conditions, inlet currents flush sediment out of the inlet to maintain its opening against longshore sediment transports that tend to close the inlet. The currents in the inlet are contributed by the tides and also from...

Een kortdurende, (zeer) zware (noord-)noordwesterstorm over de noordelijke Noordzee veroorzaakte aanzienlijke verhogingen van de waterstanden. Sinds de middelbare stormvloed van 28 januari 1994 was de waterstand bij Hoek van Holland niet meer zo hoog geweest. Tijdens het passeren van de stormvloed zijn de stormvloedkeringen in de Oosterschelde...

Sand transport processes and sediment and bedform dynamics are reviewed with emphasis on the measured processes on the shoreface between the seaward edge of the surfzone and the upper continental shelf on time scales from seconds to a year. The studies reviewed here were done off California, in the northern Gulf of Mexico, at Nova Scotia, on the...

Many coastal areas in Vietnam suffer from erosion. One of the worst affected areas is the Hai Hau beach, located in the Red River delta in northern Vietnam. Over the last hundred years, vast parts of the beach have eroded at an average rate of approximately 25 m per year. Important agricultural land has vanished into the sea and families have...
