Afridi, Z.N. (author)The purpose of this report is to investigate the differences in overtopping characteristics over the crest of a rubble mound breakwater when the crest is made either impermeable or permeable. Among numerous characteristics that are effected by a modification in the permeability of the crest, this report looks specifically into three separate...student report 2010

Van der Ham, P.J. (author)Part I: On the time scales of wave processes. To systematically improve the SWAN model a study on the wave physics in a tidal inlet was carried out. The third-generation SWAN model was used to compute the wave processes in a tidal inlet for storm conditions. The computed wave processes are propagation (shoaling, refraction and frequency shifting...master thesis 2009

Treffers, R.B. (author)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...master thesis 2009

Kranenburg, W.M. (author)On numerous locations in the world mud occurs in front of the coast close to river mouths. This mud can be transported to these places in fluid state or can become fluid under certain wave conditions. Fluid mud may have a strong damping effect on surface waves. Dissipation of up to 90% of the wave energy within a few kilometers has been measured...master thesis 2008

De Schipper, M.A. (author)Surfing as a sport is growing. Locations with good surfing conditions are limited and therefore crowded. The growing interest for the sport led to a new concept, surf pools. Surf pools mimic good surfing conditions found along the coast. This thesis is about the technical feasibility of a new surf pool concept, creating surfing waves in a...master thesis 2007

De Vries, S. (author)Wave pools are designed to mimic surfing conditions as they exist along coasts. The Liquid Time Wave Pool concept, invented by Greg Webber, suggests a new method for wave generation. Waves are generated by a hull which moves in a channel. These "ship waves" break on a slope creating surf. Key feature of the concept is to make ship waves surfable...master thesis 2007

Bijman, W.B.G. (author)Een belangrijk aspect bij het bepalen van de resulterende schuifspanning is de niet-lineaire interactie tussen golven en stroming. De grenslagen van de golven en de stroming beinvloeden elkaar wederzijds, waardoor de gemiddelde schuifspanning en de maximale schuifspanning voor de combinatie van golven en stroming groter zijn dan kan worden...master thesis 2000

Halter, W. (author)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...master thesis 1999

Van der Wal, R.J. (author)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...master thesis 1996

Van Gruijthuijsen, M.F.J. (author)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...master thesis 1996

Oschatz, E. (author)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...master thesis 1996

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...master thesis 1995

Van Agthoven, A.M. (author)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...master thesis 1994

Havinga, F.J. (author)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...master thesis 1992

Kraneveld, M.R. (author)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...master thesis 1991

Heijermans, B.H. (author)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...master thesis 1991

Daemen, I.F.R. (author)This report contains an analysis of data on wave transmission. It is restricted to wave transmission at low-crested permeable breakwaters. All data used are from tests with irregular waves. These data were earlier gatherd in Delft Hydraulics' report: "Data on wave transmission due to overtopping by J.W. van der Meer ((1990). Aim of the research:...master thesis 1991
