Van der Zwaag, J. (author)In the mass balance of a riverbed, some terms are usually assumed constant for reasons of simplicity. One of the terms assumed to be constant is the change in bedload layer, which is defined as the sediment transport divided by the particle velocity. To study the effect of this assumption, a numerical morphodynamic model has to be computed. For...bachelor thesis 2013

Termes, A.P.P. (author)In order to predict waterlevel changes in rivers due to floodwaves and local bedshapes for navigation, the local behaviour of the riverbed should be known . In many cases the bed of 3 river consists of dunes, which propagate downstream due to the sediment transport along the dunes . In this report mainly the watermovement but also the sediment...master thesis 1984

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...master thesis 2013

Balsters, A. (author)Naar aanleiding van de hoogwatergolf op de Maas in 1993 werd door de Minister van Verkeer en Waterstaat de Commissie Boertien 11 ingesteld, met als opdracht te adviseren op welke wijze de hoogwateroverlast in het Maasdal in de toekomst beperkt kan worden. Het advies luidde in hoofdzaak een verbreding van de Grensmaas en een verdieping van de...master thesis 1998

Hendriks, A.J.H. (author)Objective Due the coastal protection program along the Dutch coast, the groins that first defended the coast against erosion, are now covered under sediment. Due to erosion the covered groins will resurface however. The objective of this study is to investigate the effect of the resurfacing groins on the hydrodynamics and sediment transport....master thesis 2011

Cloin, B. (author)The main goals of this study are to obtain more insight and quantitative data of the selective transport process under sheet flow conditions. Experiments were carried out in the Large Oscillating Water Tunnel of WL DELFT HYDRAUUCS for five different hydraulic conditions. The sand that was used consisted of a mixture of 50% fine (0. 13mm) and 50%...master thesis 1998

Van Bentum, K.M. (author)The Lagos coast has been suffering high rates of erosion since the construction of three harbour moles, i.e. the West Mole, East Mole and the Training Mole, at the tidal inlet connecting the Lagos Lagoon to the South Atlantic Ocean. To provide for a permanent erosion mitigation measure and to create residential and commercial area for circa 400...master thesis 2012

Tilmans, W. (author)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...master thesis 1989

Hopmans, R. (author)For many applications in the field of coastal engineering 2D-morphological models are being applied. Due to the large computational effort these models demand it is nearly impossible to include a full wave climate in long-term morphological modeling. This has asked for waveclimate reduction methods in order to reduce the input and consequently...master thesis 2013

Hoogduin, L. (author)The aim of this research is to determine to what extend the scour holes limit the sediment transport through the Eastern Scheldt storm surge barrier and whether or not human adaptations, like sand-nourishments in the scour holes, can have a positive effect on the sediment import. To investigate these scenarios a numerical model (Delft3D) is used...master thesis 2009

Westgeest, T.W. (author)This study focuses on time-averaged sediment transport in oscillatory flow in the sheet flow regime. The tests, used in this study, are part ofthe experiments, carried out under the name SISTEX99 (Small-scale International Sediment Transport Experiments 1999). SISTEX99 focuses on near-bed sediment transport processes under influence of regular...master thesis 2000

Van Os, P. (author)In de kust- en waterbouw worden regelmatig geometrisch open filterconstructies toegepast. Er bestaat onduidelijkheid over het doordringen van de hydraulische be lasting in de filterlaag en de invloed daarvan op de erosie van de basislaag. Eerder onderzoek geeft het verband aan tussen de schuifspanning op de filterlaag en schuifspanning op de...master thesis 1998

Mols, H.J.M.A. (author)Gradients in sediment transport due to waves and currents cause coastal changes and sediment transport is an important subject in coastal engineering research. It is therefore necessary to predict the sediment transport rates in the coastal region. Various formulae are available to predict the sediment transport rates, for example the sediment...master thesis 2001

Van der Hout, G. (author)This study consists of three sections: - experiments on sand transport in oscillatory sheet flow with two sands (D50 = 0.21 and 0.32 mm) - verification of three existing sediment transport models - extension of these models to include the gradation of the sediment The experiments are performed in the Large Oscillating Water Tunnel (see also data...master thesis 1997

Schepers, J.D. (author)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...master thesis 1978

van den Ende, I.C. (author)This study investigates wave driven onshore sandbar migration. Observations show that sandbars move onshore during mild wave conditions. Literature describes different potential sediment mechanisms that cause this onshore migration, but the dominant cause is still under debate. The goal of the present study is to determine the dominant sediment...master thesis 2017

De Bruijn, R.A. (author)After the storm surge of 1953, the Dutch Delta project was initiated in order to protect the southwestern part of The Netherlands. A storm surge barrier in front of the Oosterschelde and various dams at the back of the estuary were constructed. These interventions led to a large change of the hydrodynamics of the Oosterschelde: a large decrease...master thesis 2012

Marangoni, G. (author)In this report the sediment transport at Parachique, Peru, is calculated. This has been done in two different ways. First the Bijker method has been applied. This has been done by taking the significant wave height as representative for the wave spectrum and by chosing an equivalent wave height as representative for the significant wave height...master thesis 1985
