Additional thesis - Historical engineering works such as weirs, land reclamation and large scale deepening modified not only the local morphology and hydrodynamics but also tidal characteristics and sediment transport patterns in the tidal river Ems. The loss of intertidal area and ongoing deepening contribute to the flood dominance while...

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...

A 2Dnumericalmodel is set-up for the tidal bore in the Sittaung River. This model is used to analyse the effect of the bottom friction, bathymetry, tidal range and river discharge on the propagation of the tidal bore. To obtain information about the tidal bore the Sittaung River is visited two times. During the second visit, depth measurements...

A shoal connecting channel connects two main channels over a shoal area. Shoal connecting channels are dynamic in their behavior and create areas alternating in height. By doing so the connecting channels make the area ecologically more valuable. Over time the dynamics of the shoal connecting channels in the Westerschelde have decreased. The...

The objective of this study is to identify the mechanisms that drive the morphodynamic behaviour of the sediment disposals in the subtidal zone north of the intertidal shoal Walsoorden. The morphological development of the sediment in the subtidal zone near this shoal has been monitored and measured. The gathered bathymetric data show that one...

Coastal regions change continuously due to natural processes. Human activities in coastal regions require a steady environment. Usually the dredging industry is contacted for coastal maintenance. Knowledge about the time development of sediment volume changes in specific regions is necessary for risk assessment in contracting. Nearly a century...

The Guayas River estuary supports extensive socio-economic processes. It is formed at the confluence of the Babahoyo and Daule Rivers and runs for around 65 km before discharging into the Pacific Ocean. Its relevance within the national context is linked to the city of Guayaquil, the most populated city and commercial capital of Ecuador....

This study is about the effect of outer-delta bottom topographies adaptations on salt water intrusion in estuaries. An increase in salt water intrusion is considered as problematic in a lot of estuaries in the world. Various solutions are developed in the past to reduce salt water intrusion. These solutions have also negative side effects. An...

The overall behaviour of the tide-dominated Western Scheldt is in general well known. Its multichannel-system consists of ebb and flood channels, separated by intertidal areas; the tidal flats. The estuary shows a dynamic behaviour of erosion and sedimentation of the tidal flats. A large flow slide occurred at the tidal flat of Walsoorden in...

In the last century, various tidal rivers in Europe have seen a large tidal amplication, which is believed to be caused by the deepening and channelization of these rivers. Additionally, large increases in suspended sediment concentrations induced by flood dominance are thought to have decreased the effective hydraulic drag, enhancing further...

Depth-averaged morphological computations using Delft3D tend to produce ‘strange’, results for river bends when the sediment transport formulas of Van Rijn are used. Even pools in inner bend regions and bars in outer bend regions can result from the model. The objective of the present thesis is to identify the cause of the problem and propose...

The Dutch Wadden Sea is consisting of 7 tidal inlet systems separated by sandy barrier islands. The general morphodynamics and hydrodynamics of tidal inlets are relatively well understood, but the detailed interactions remain a prominent research interest. In this study, process-based computer models are employed as a tool to investigate the...

Dispersion is often hard to incorporate in analytical salt intrusion models. The analytical models of Savenije (1986) and Kuijper & Van Rijn (2011) are quite similar and use a predictive equation for the dispersion in the estuary mouth. The biggest difference between the two models is the Van der Burgh K for which Kuijper and Van Rijn stated...

The city of Itajaí is located in the province of Santa Catharina in Brazil. The people of Itajaí have been coping with flood risk for the past decades. During normal conditions the Itajaí-Açu River is a rather calm river that is used for navigation and the harbour area. Recovering from the past two floods in 2008 and 2011 have cost more than...

With the development of a process-based model (Delft3D) of the St Lucia Estuary inlet, a first approach is made with regard to the estuary mouth dynamics and closure mechanisms that are observed at St Lucia inlet. The purpose of this thesis is to get a better understanding of the hydrodynamic and morphological behaviour of the St Lucia inlet...

The objective of this project is to assess the influence of suspended sediment on hydrodynamic properties in the study area from tidal damping aspect. Firstly, through conducting tidal amplification factor analysis based on real time measured data, seasonal variation in sloping tendency has been observed. The difference in sloping tendency...

After the storm surge of 1953, the Dutch Delta project was initiated in order to protect the southwestern part of The Netherlands. A storm surge barrier in front of the Oosterschelde and various dams at the back of the estuary were constructed. These interventions led to a large change of the hydrodynamics of the Oosterschelde: a large decrease...

The research objective of this thesis is to determine the new hydrodynamic and morphodynamic situation in case the Oosterschelde storm surge barrier is removed, with emphasis on the development of the intertidal area. To reach the objectives of this study a literature study is performed which describes the impact of the Deltaworks. An analytical...

Scheel, F. (author)
Tidal inlet systems, as found in the Dutch Wadden Sea, often feature both sand and mud. Due to differences in sediment properties, sand and mud particles respond different to identical forcing conditions, like short waves and tidal currents. Because of this, sand and mud can get transported to different locations. This process is referred to by...

Nowadays, the ecological effects of dredge plumes are usually managed based on the precautionary principle. Predictions of suspended sediment levels are made, which have to be compared to thresholds set by the responsible authority. Failing to comply may cause a project to be delayed and thus lead to additional costs. The precautionary principle...
