Around the world, areas with unique ecosystems are prone to harmful factors deteriorating their environment. Management of these areas need knowledge on the ecological status of these areas, to make decisions for future problems. They need easily accessible information on indicators describing the conditions of these areas. Obtaining this...

Additional thesis - The Rhine river outflow has a major impact on the North Sea in front of the Dutch coast. It creates the Rhine ROFI (region of freshwater influence), a very complex three-dimensional volume of water with a relatively low salinity. Many researches have been conducted on this phenomenon. Now another complex factor is added: a...

This thesis investigates the origin of observed current velocities at the Gemini offshore wind farm in 2015. Currents have been measured of 1.2 m/s while, based upon tidal and storm predictions, currents of only 0.7 m/s were expected. The aim of this research is to gain insight into the origin of these higher currents, taking into account the...

FLNG cooling water outfalls can be characterized as high momentum buoyant jets, relatively close to the surface. The buoyant jet trajectories, spreading rates and surface distribution very much depend on the jet outflow characteristics. A study with the CFD software OpenFOAM has been carried out into the mixing and transport processes of buoyant...

The 2010 Chile megathrust earthquake, with a magnitude of 8.8 on the Richter magnitude scale, occurred on February 27, 2010 at 06:34 UTC and initiated a devastating tsunami which severely hit the central coast of Chile. An intriguing aspect of this tsunami is the delayed arrival of a destructive wave, larger than the initial wave, at Talcahuano...

Numerical modelling for environmental flow applications, such as for rivers, lakes, estuaries and coastal flows, faces a trade-off between the numerical accuracy and the required computation time. This trade-off results in grids which typically contain 10 to 100 layers in the vertical direction. Such a grid resolution poses severe limitations to...

The topic of this paper is the study of the tidal velocity profiles within a region of fresh water influence (referred to as ROFI in this paper). These regions of fresh water influence occur where rivers discharge fresh water into salty seas. The main research question is how depth influences the behaviour of the tidal velocity profile in a...

In this master thesis the residual circulation in the North Sea is investigated. It has been shown that the numerical models used in this thesis (DCSMv5 and DCSMv6) give a rather low representation of the actual circulation pattern in the North Sea. The dominating forces which cause residual currents in the North Sea are the tidal forcings,...

The Rhine River and the Meuse River discharge into the southern North Sea, and form the Rhine Region of Fresh Water Influence (ROFI) in front of the Dutch coast. A complex hydrodynamic system is generated, dominated by mixing from strong tides, wind and waves and the stratifying influence of the freshwater and solar heating. This influences the...

Rijnsdorp, D.P. (author)
Infragravity waves are a common feature in the nearshore wave field and have a significant impact on numerous coastal processes. It is therefore important to accurately predict infragravity wave conditions at a given location. However, analytical relations do not exist with which to make such predictions and one has to rely on numerical models....

This Master Thesis presents a numerical model analysis of the response of the Rhine ROFI on wind direction and speed. The aim of this study is to gain a further insight in the physical processes of the Rhine ROFI. Previous work on the Rhine ROFI focused mostly on tidal effects (straining and mixing) and inertial motions (earth rotation). Other...

The data content of remote sensing (RS) images of sea surface temperature (SST) and normalized water-leaving radiance (nLw), for the year 1998, with respect to the River Rhine plume, is investigated. Questions that this study tries to answer are: is it possible to identify the plume from the available RS images, and under which conditions is...

When a river discharges into the sea it forms a river plume. The main property of these plumes is their buoyancy; fresh water discharged by rivers is less dense than the receiving, saline waters. Due to the rotation of the Earth, these plumes tend to turn to the right in the Northern Hemisphere after entering the sea. Previous studies...

Storms that come ashore across wide, shallow, continental shelves cause extreme changes in the sea level at the coast; these are called storm surges. Basically, these surges can be divided into two types: surges due to mid-latitude storms and surges caused by tropical cyclones. Due to lack of warning and insufficient preparation, these surges...

Modelling of cohesive sediments is of paramount importance for water quality issues: cohesive sediments control the light extinction and they are the major carriers for heavy metals. The concentration of cohesive sediments in open water systems is too a large extent controlled by erosion from and deposition to the waterbed. The permanent opening...
