Pieters, T. (author)
Summary of the graduation work published at the ICCE: In the present investigation the influence of bottom slope on mass transport by progressive waves was investigated, both theoretically and experimentally. Theoretical considerations based on linear wave theory show the greatest influence of the slope on the bottom drift velocities for...

Er zijn door o.a. Vetlinga en Schepers proeven gedaan in een laboratoriumgoot ter bepaling van zandtransport in de voortplantingsrichting van golven onder invloed van die golven. Doel van deze proeven is om neer inzicht te krijgen in de opwoeling van het bcdemmateriaal aan de bcdem en op die manier in het zandtransportmechanisme . In al die...

A wave entering a harbor will be diffracted and reflected, depending on the shape and the construction of breakwaters, quays and other objects in the harbor. The incoming wave can increase or decrease in height and a resonance can occur. This affects the manouvering of ships and the movement of moored ships, which influences the loading and...

The final objective was to evaluate the stability of an offshore pipeline from a geotechnical point of view. On the Dutch part of the Continental Shelf pipelines are used for the transportation of oil and gas and utilities liRe glycol. The mean waterdepth on this part of the North Sea varies from 20-40 meters. As this region is a major fishing...

In many coastal, engineering problems the sediment transport plays a part. A transport gradient causes accretion or erosion. Various models, such as that of Bijker, Engelund and Hansen (van de Graaff and van Overeem, 1979) and Nielsen (1985) are available to estimate the sediment transport rate if the hydraulic and environmental conditions (wave...

Deel II bevat het derde deelverslag uit maart 1988 waarin de dynamische golfbreker constructief wordt uitgewerkt. En waarin ook een kostenschatting van de dynamische golfbreker in het Ekofisk veld is gemaakt. De dynamische golfbreker is een golfdempingssysteem bestaande uit een groot aantal boeien die onder het zeeoppervlak verankerd worden, en...

Investigation to sediment transport rate in case of waves and currents, tests executed in the wave-current flume of the laboratory of Fluid mechanics of TU Delft. Sediment transport was measured using sand of 100 micron; comparison to similar tests with 200 micron sand.

Sediment transport causes morphological changes of coastal areas, and it is one of the most important objects in coastal engineering study. Recently, various experiments have been performed to investigate the sediment transport mechanism under a combination of waves and currents and to find the underlying relationships among various parameters...

Sediment transport by waves in the direction of the waves in relatively shallow water. Het onderzoek naar zandtransport in meest algemene Zin kent al een ruime historie. In eerste instantie lag het accent hierbij op bestudering van het zandtransportverschijnsel onder invloed van een permanente stroom, zoals in rivieren en kanalen. Daarbij is in...

BELUGA is a mathematical model which has been developed by Booij, Holthuijsen and Tolman in Delft University of Thechnology, to compute wave penetration into a harbour taking diffraction and reflection into consideration. The aim of the model is to provide an efficient numerical method for calculation of a wave field in a relatively large...

This is a study of the statistics of the ocean surface. The extreme surface elevation arising from waves, tides and storm surge is calculated by a novel approach that appears to eliminate many of the shortcomings of the convential practice. The proposed method works with the statistics of storms rather than three hour periods. A storm may be...

In conventional practice extreme design conditions for offshore structures are obtained very conservatively by extrapolating 3-hourly statistics of wind, wave and current data to a (say) 100 year return level, assuming that the 100-year extremes occur simultaneously and act in the same direction. This study involves an alternative approach...

The present report contains a description of an experimental program, as a follow up of experiments by v.d. Kaaij and Nieuwjaar in 1986, and Nap and Van Kampen in 1987. As in the second study, in the present study a particle sand diameter of D50 = 100 mu was used, so that the experiments of Nap and Van Kampen will be referred as "the earlier 100...

Detailed studies have been carried out for fetch and duration limited wave growth and fully developed sea state, but much less is known about changing wind conditions. The subject of this study is the response of waves to a change in wind speed. The main point of interest is the rate of response at the different frequencies. Two third generation...

Bosboom, J. (author)
In this thesis, the modelling of the horizontal velocity field under waves using Boussinesqtype models is studied. Special attention is paid to the prediction of bottom velocities in view of sediment-transport formulations. Boussinesq-type models describe the propagation of weakly non-linear shallow-water waves. The depth-dependence of the...

In this thesis, the wave prediction model SWAN is validated on field data obtained from wave growth experiments that were done in Lake George, a shallow lake in Australia. SWAN, which is an acronym for Simulation of WAves in Nearshore areas, is a numerical model, developed at the University of Technology in Delft, to obtain estimates of wave...

HISWA is een tweedimensionaal golvenmodel, dat de gebruiker in staat stelt diverse golfgegevens, zoals significante golfhoogte, periode en golfrichting, voor een bepaald modelgebied te bepalen. Op dit moment biedt HISWA al faciliteiten om pre- en postprocessing uit te voeren (zij het in beperkte mate). Onder de gebruikers echter is er behoefte...

Especially during storms the coast-profile can change dramatically. During storms large waves cause high oscillatory water velocities near the bottom and the bed becomes plane and sheet flow becomes the dominant sediment transport mode. Because field measurements are difficult to perform in-situ, laboratory experiments concerning these processes...

Filterconstructies hebben als doel erosie te voorkomen in bepaalde delen van waterbouwkundige kunstwerken. Ze zijn opgebouwd uit een basislaag en een of meer filterlagen. Er zijn verschillende soorten filterconstructies. Ze worden over het algemeen zo gemaakt dat er geen erosie zal optreden van basismateriaal. Het is echter efficienter om een...

Recent study has shown that 3D computations of the morphological development of a coast shows irregularities compared with the 2DH (depth-averaged) computations. Therefore a validation of the surf zone currents computed using the 2DH (depth-averaged) and 3D approach in Delft3D is made. The 2DH and 3D approach are compared using an idealized case...
