Episodic density-induced current velocities at the Gemini offshore wind park

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...

Numerical modelling of the growth of offshore sand waves: A Delft3D study

Offshore sand waves of several meters high and hundreds of meters long are formed in shallow seas due to the tidal currents. These sand waves can, amongst others, influence the burial depth of cables of offshore wind farms and obstruct navigation channels. For the Far Large Offshore Wind programme (FLOW), one of the goals of Deltares is to...

A modelling study on the residual circulation in the North Sea, with the focus on water fluxes through the Strait of Dover

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,...

Developing a parametric model for storms to determine the extreme surge level at the Dutch coast

To date no study has been done to analyse the effect on water level for the Dutch coast from the passage of storms over the North Sea. This research examines the feasibility of developing a joint probability method to determine the extreme water level for the Dutch coast, resulting from these storms. This has been done by means of a parametric...

Remote sensing of the river Rhine plume

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...

Schiphol in zee: Golfdiffractie om het eiland

In deze studie is de invloed van golfdiffractie onderzocht op het golfveld achter een eiland in de Noordzee op 10 km uit de kust. Dit onderzoek is uitgevoerd als afstudeeropdracht voor de studie Civiele Techniek aan de Technische Universiteit Delft. Het aanleggen van een eiland voor de Nederlandse kust heeft consequenties voor deze kust. Door de...

Het poldermodel in de luchtvaart

De infrastructuur voor de luchtvaart in Nederland dreigt tekort te gaan schieten. Er zijn in de media en in de Tweede Kamer grate discussies gaande over het hoe, waar en waarom van een uitbreiding. In dit afstudeerproject is gekeken naar de mogelijkheid van de (gedeeltelijke) verplaatsing van de luchthavencapaciteit naar een luchthaven in de...

Response of a shelf water to a traveling atmospheric pressure disturbance

Every harbour has its own uniques et of natural frequencies depending on its geometry. If waves with frequencies close to one of these natural frequencies continue to enter from offshore for some time, the harbour will resonate. This phenomenon is called harbour resonance or seiching and the characteristic oscillations seiches. A moredetailed...
