Wei, X. (author), Kumar, M. (author), Schuttelaars, H.M. (author)Along-channel and cross-channel sediment transport in tidal estuaries is usually driven by tides, density gradients, Coriolis’s force, wind stress, channel curvature and bathymetric variations. Since the water motion is influenced by density-induced gravitational circulation which in turn affects the salinity distribution, the coupled water...abstract 2016

Vuik, V. (author), Jonkman, Sebastiaan N. (author)Salt marshes are a characteristic feature of estuaries and coastal seas. They are found in the upper coastal intertidal zones between land and water, which are regularly flooded by tides and surges. They are covered with salt-tolerant vegetation types, such as herbs and grasses. Sheltering from continuous intense hydrodynamic forcing by waves...abstract 2016

Lugt, D. (author)The Ems estuary suffers from high concentrations of suspended sediment, which is harmful for the life in the river. Sediment import occurs because of tidal asymmetry, a difference between the velocity of the current during high tide and low tide. The use of retention basins are a possible measure to reduce the tidal asymmetry. An analytic model,...bachelor thesis 2012

Berghuijs, W.R. (author), Van Osnabrugge, B. (author)Recently, a promising method for measuring tidal slack using GPS receivers attached to buoys has been tested. The next step is to build a wireless GPS system which conducts measurements continuous and real-time. This research primarily focuses on the development of the hardware of that GPS system. Secondly it focuses on modeling the buoy...bachelor thesis 2012

Sindy, F. (author)In this thesis the water motion and sediment dynamics are investigated in a periodically closed and opened estuary. The water motion in an estuary is mainly driven by the semi-diurnal tide with an period of 12h25m and river discharge. An example of such an estuary is the Ems-Dollard estuary. Recent observations show an increase in tidal range ...bachelor thesis 2020

Hunter, Conor (author)This research study has investigated the effects of sills as a nature-based countermeasure to reduce saltwater intrusion within Rijnmond Drechtsteden. The effects of this measure have been assessed regarding its impact on port logistics and freshwater supply in the region. The heavily dredged New Waterway provides the vital open connection to...bachelor thesis 2023

de Groot, Hugo (author)The salinity profile in a coastal sea-river system is the result of balancing of salt transport due to mixing of the water by tides and the freshwater discharge from the river. When for example during times of drought freshwater discharge suddenly declines, the salinity in the river may increase significantly and threaten drinking water supplies...bachelor thesis 2023

de Jongh, Thijs (author)In this thesis the hydrodynamic behaviour of an idealised relatively short tidal estuary is studied using a cross-sectionally averaged model, i.e. a one dimensional model. The geometry of the estuary is simplified and only the hydrodynamic processes are considered. This model is used to gain insight in the behaviour of currents and water levels...bachelor thesis 2020

Usman, Nerine (author)Over time, the width-averaged depth of estuaries changes due to a complex interaction of hydrodynamics and suspended sediment transport. In many estuaries one specic location with a suspended sediment concentration (SSC) higher than in the sea or in the upstream river, is found, which is called sediment<br/>trapping. The location of the maximum...bachelor thesis 2017

Bakker, W.T. (author)Contains basic paper plus background supplements. Areas like the Western Wadden area have a length of approximately 1/4 of a tidal wave length. Therefore tidal motion is sensible for resonance. It is investigated, under which circumstances morphological instabilities may occur. Instabilities are defined in this way, that small depth increments...conference paper 1993

(author)In this paper we explore the role of the river run-off, the tidal regime and the local winds in the dynamics of the Ria de Arousa estuary during the summer period, using for that purpose the numerical model Delft3D. First of all, a simulation under real hydrological and meteorological conditions is conducted in order to validate the ability of...conference paper 2013

(author)The present paper describes an analysis of the morphological integrityof the multiple channel system (MCS) of the Western Scheldt estuary. The tidal flats and surrounding ebb and flood channels form morphological cells, and the entire MCS can be schematized as a chain of such cells. The major ebb and flood channels have lost their one time...conference paper 2001
