Effect of an artificial oyster reef on wave attenuation

An increasing amount of the worlds coastal regions suffer from structural erosion due to anthropogenic influences. A prime example for this phenomenon is the Oosterschelde, Netherlands, where the partial closure of an estuary lead to a decline of the local intertidal flats, threatening the valuable functions they provide as an ecosystem and for...

Using small scale morphological features on estuarine tidal flats as indicators for large scale morphological shape and development

Intertidal flats and salt marshes can protect hinterland against wave energy and flooding by tides or storm surges. Thus, the development of tidal flats is important to foresee. The presence of specific small scale features could indicate a certain development and large scale morphological shape. The shape is a predictor for development and it...

Stabiliteit van tweegeulensystemen in estuaria; De invloed van plaat-geulinteractie nader beschouwd

In estuaria zoals de Westerschelde komen eb- en vloedgeulsystemen voor. Dit zijn twee geulen, gescheiden door een plaat, waarin de ene geul netto een stroming in zeewaartse richting kent (ebgeul), en de andere netto een stroming landinwaarts (vloedgeul). Menselijke ingrepen zoals baggeren en storten zullen een verstoring veroorzaken in het...

A model of the morphological behaviour and stability of channels and flats in tidal basins

In this report, a model is derived which simulates the behavior of channels and flats in a tidal basin after a change in the exogenous parameters. In chapter 1, a short introduction is given about the context in which this research has been done. Chapter 2 discusses the general features of the tidal inlet system as well as its formation and...

Thesis small scale equilibria in tidal basins: A data-analysis and case study in the Ameland Inlet

The behaviour of tidal basins has been predicted using a modelling approach in which a morphological equilibrium for an entire basin was used frequently in the past. Because tidal basins have, to an certain extend, a fractal nature, it is expected that this approach could be used with a morphological equilibrium for subbasins as well.<br/><br/...

The Wind of Changes on the Kapellebank Tidal Flat, The Westerschelde

The existence of tidal flat is beneficial for human beings, but it faces the risk of being vanished by continuous intervention, either by nature or human. Therefore, researches about tidal-flat’s morphodynamics are required for the sake of its preservation. Here, the subject of the research is the Kapellebank tidal flat in the Westerschelde...

Tidally- and Wind-Driven Horizontal Flow Patterns on Intertidal Flats in the Wadden Sea: An Assessment using Subgrid Modeling Technique

The Wadden Sea is of great ecological importance. Key elements in the Wadden Sea are the extensive intertidal flats. These contain vast amounts of life, serve as feeding grounds for millions of birds, and provide ecosystem services such as coastal protection. It follows that it is important to be able to understand and predict how these vital...
