Homogeneous detached composite breakwater: CFD study of the design sensitivities in the 2D geometrical layout using a detached homogeneous low-crested structure to reduce sea wall overtopping

Jonker, R.G. (author)

In this research OpenFOAM is used to model and determine the complex hydrodynamic behaviour of a Homogeneous low-crested structure (HLCS) consisting of cubipod artificial concrete elements. The validated model is used to gain insight in the design sensitivities of a two dimensional cross sectional layout to reduce sea wall overtopping. HLCS and...

Depth-averaged unsteady RANS simulation of resonant shallow flows in lateral cavities using augmented WENO-ADER schemes

Navas-Montilla, A. (author), Juez, C. (author), Franca, M.J. (author), Murillo, J. (author)

Turbulent shallow flows are characterized by the presence of horizontal large-scale vortices, caused by local variations of the velocity field. Apart from these 2D large vortices, small scale 3D turbulence, mainly produced by the interaction of the flowing water with the solid boundaries, is also present. The energy spectrum of turbulent...

Hydrodynamic Drivers of Sediment Transport Across a Fringing Reef

Bodde, W.P. (author), Pomeroy, A.W.M. (author), Van Dongeren, A.R. (author), Lowe, R. (author), van Thiel de Vries, J.S.M. (author)

Coral reefs are highly valuable ecosystems, which are under an increasing number of environmental pressures. Sedimentation and sediment transport patterns are among key physical drivers of coral reefs, so it is important to improve our understanding of these poorly studied dynamics on reefs. To this purpose, flume experiments were performed on a...

Sediment transport in a fringing reef environment: Analysis using laboratory experiments and numerical modelling

Bodde, W.P. (author)

Coral reefs are highly valuable structures in many respects and it is increasingly important to understand hydrodynamics and morphodynamics around reefs to be able to better protect them and their hinterland. Flume experiments were performed on a scaled fringing reef in the laboratory facilities of Deltares in Delft. The objective of this thesis...

Origin and prediction of seiches in Rotterdam harbour basins

De Jong, M.P.C. (author)

This thesis focuses on the harbour oscillations that occasionally occur in certain basins of the Port of Rotterdam. Such standing waves, called seiches, need to be taken into account in this harbour area for the design of water protection works (such as dykes) and for the closure management of a movable storm surge barrier, located along the...

Boundary Conditions for a Seiche model

De Haas, E. (author)

The Storm Surge Barrier in the New Waterway was built to protect the city and port of Rotterdam and the area of the lower Rhine against flooding during extreme conditions. This construction, consisting of two gigantic arc shaped barriers, is to be pivoted into the New Waterway and then lowered in case of an impeding emergency. The arc shape...

Seiches in het Europoortgebied: Numerieke modellering van de zeerand in een ééndimensionaal model

Méndez Lorenzo, A.B. (author)

Seiches zijn opslingerende staande golven die in afgesloten havenbekkens kunnen ontstaan, wanneer vanaf zee golven met specifieke golflengtes de haven binnen dringen. In het Europoortgebied ontstaat een afgesloten bekken wanneer de stormvloedkering in de Nieuwe Waterweg en de Hartelkering worden gesloten. Seiches veroorzaken een extra verval...

Response of a shelf water to a traveling atmospheric pressure disturbance

Kirkegaard, L.C. (author)

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...

Het bepalen van opslingerfaktoren in vertakte kanaalsystemen

Marks, C.H. (author)

De oorspronkelijke doelstelling was na te gaan, hoe in IJmuiden de gunstigste situering voor een nieuwe sluis gevonden kon worden. De meest gunstige situering is die, waarbij het optreden van seiches, dus van golfverschijnselen, minimaal is. Deze doelstelling is gewijzigd tot het maken van een systeem ter bepaling van de opslingerfaktoren in een...
