A width-averaged hydrodynamic model of two-layer tidal circulation

Estuaries support a unique hydrodynamic system due to the fresh water flowing into a salt water sea. This leads to stratification which can significantly alter internal tidal dynamics in the estuary. A model has been developed by Winant (2010) to describe the water motions of a two-layer system in tidal basin. The aim of this thesis is provide...

Idealised tidal dynamics in an estuary with a horizontally movable time dependent barrier: A contribution to one of the possible solutions of the sludge problem in the Eems estuary

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...

The influence of time dependent vertical mixing on suspended sediment in the Ems estuary

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...

An Idealised Morphodynamic Model of a Tidal Inlet and the Adjacent Sea

Tidal inlet systems are often highly valuable and sometimes even unique ecosystems. However, field measurements show that tidal inlet systems are sensitive to changing exogenous conditions, such as rising sea levels. This thesis aims to investigate to what extent the adjacent sea influences the stability and equilibrium state of the tidal inlet....
