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/...

Channel nourishments to feed the eroding flats in the Eastern Scheldt

The tidal channels in the Eastern Scheldt basin, are out of equilibrium due to the reduced tidal prism as a consequence of the construction of the Storm Surge Barrier in 1986. An estimated 500 million cubic meters of sediment is required in order to reduce the cross-sectional areas of the tidal channels such that the system reaches a new...

On the Impact of Salt Marsh Pioneer Species-Assemblages on the Emergence of Intertidal Channel Networks

Tidal marshes play an important role in climate change mitigation through natural coastal protection. The effectiveness of the natural coastal defense by tidal marshes is closely related to their channel network which is in turn greatly influenced by their vegetation cover and shape. Previous research suggests a dual effect of vegetation on...

Tidal Meanders in the Ameland Basin: A study to the underlying processes in the evolution of tidal meanders

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...

An analytical approach to determining resonance in semi-closed convergent tidal channels

An analytical model is used to investigate the resonant behavior in a semi-closed channel. The main integral quantities of the tidal wave are obtained by means of a linearized one-dimensional model as a function of three dimensionless parameters, representing cross-section convergence, friction and distance to the closed boundary. Arbitrary...

Numerical analysis of stratification and destratification processes in a tidally energetic inlet with an ebb tidal delta

Stratification and destratification processes in a tidally energetic, weakly stratified inlet in the Wadden Sea (south eastern North Sea) are investigated in this modeling study. Observations of current velocity and vertical density structure show strain-induced periodic stratification for the southern shoal of the tidal channel. In contrast to...

Hydrodynamic analysis of the Johor river estuary

Singapore’s coastal waters are characterised by relatively complex tidal behaviour due to it’s location between two large oceans with different tidal regimes. This complex tidal behaviour results in poor understanding of the hydrodynamics and sediment dynamics. The hydrodynamics of the Johor River estuary, including part of the Singapore Strait...

Description of the turbulence measurements conducted in the tidal channel "Groote Gat" (Ems/Dollard) in 1995 and 1996

In 1993 an interdisciplinary research programme on the behaviour of mud in tidal waters was initiated by the Board of NWO-BOA. The programme aims at obtaining more detailed insight in the dominant processes that govern the transport behaviour of mud. These processes have strong time variability and therefore the general approach is to obtain...

Nederlandse slufters: Verkennende inventarisatie naar abiotische parameters

Simulation of flow in rivers and tidal channels with an implicit finite difference method of the ADI-type

In order to make predictions for the morphology of an alluvial bottom a thorough knowledge of the flow pattern is needed. In tidal channels, without a nett discharge over the tidal period, the main flow effects on the morphology will, on an average, remain relatively small because of the tidal variation. Therefore second order flow phenomena...

Eb- en vloedschaar systemen in de Nederlandse getijwateren - Ebb and Flood channel systems in the Netherlands tidal waters

The present paper, "Eb- en vloedschaarsystemen in de Nederlandse getijwateren" (Ebb- and floodchannel systems in the Dutch tidal waters), which was published in 1950, should be considered as Van Veen's most important publication since his thesis. It summarizes the results of 20 years of intensive study of estuarine and tidal-basin morphodynamics...
