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...

Assessment of beach face slope extraction and monitoring with ICESat-2: from local to global level

Coastal areas are appealing for human beings and are the most populated areas of the world. Therefore, coastal processes have large impacts on economy and on millions of people's lives. Not only processes such as erosion, extreme events, and flood events must be understood and monitored, but the uncertainty given by the rapid climate change on...

Room for the Wadden Sea: Analysis of a building with nature approach to strengthen the foreshore at Koehool-Lauwersmeer

A significant part of the Netherlands lies below sea level. The Dutch have protected their land against seawater since the 10th century. Nowadays, the Netherlands is protected by 3800 km of primary flood defences. Since the Flood Defences Act was included in the Dutch law in 1996, all flood defences are tested against the national safety...

Morphological development of the Bollen van de Ooster: A potential hazard for Goeree-Overflakkee?

The Bollen van de Ooster, in this report referred to as the Ooster, is a sand bar in the outer delta of the Grevelingen. The Ooster is separated from the coast by a relatively deep channel, called the Schaar. Closure of the Grevelingen in 1971, with the construction of the Brouwersdam, initiated vast changes in morphology. Damming of the estuary...

Hydraulic and morphological impact of a closure dam in the Gulf of Khambhat

Tidal basins are highly dynamic environments with a complex behavior that is often disturbed by human activities. Considering that tidal dynamics have a direct impact on surrounding engineering infrastructures, adjacent coastlines, nature environment and socio-economic human activities, it is crucial to know the impact of human interventions on...

Morphodynamics of the Haringvliet ebb-tidal delta: Unravelling the mechanisms behind its morphological evolution

<b>KEY POINTS:</b><br/>• While the formation of the intertidal shoal Hinderplaat was a direct consequence of a human intervention, its degradation was a natural response of the system to frequent hydrodynamic forcing conditions.<br/><br/>• Tidal currents push the Hinderplaat in offshore direction, but this is counteracted by waves: these...

Drempel van Valkenisse

De Westerschelde is een drukke vaarroute voor schepen die vanaf de Noordzee de havens van Antwerpen, Vlissingen en Temeuzen aandoen. Om de havens van Antwerpen in de toekomst bereikbaar te maken voor schepen met een grotere diepgang, wordt de vaargeul in de Westerschelde verdiept. Dit is voomamelijk nodig op de drempels. Drempels zijn...

Rip currents, morphodynamic simulations

Rip currents are narrow and intense, offshore directed flows in the nearshore zone. A rip current is able to transport a considerable amount of water and sediment seaward and may dominate the morphological exchange between surfzone and the offshore. Rip currents are often located nearby lateral boundaries that obstruct the longshore current, but...

Morphological modelling of tidal inlets in the Wadden Sea

The purpose of this study is to develop a suitable model to predict morphological changes in tidal inlets. Several morphological models already exist, but they all have their limitations. In this study is chosen for the morphological program ESTMORF. Until this moment the model ESTMORF is only verified for the channel cross-sectional areas and...
