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

Caan, C.P. (author)In Nederland wordt, ter vervanging van de huidige ontwerpmethodiek op basis van een overschrijdingskans, gewerkt aan een nieuwe, probabilistische ontwerpnorm voor de zee- en rivierdijken. Deze nieuwe norm wordt gebaseerd op een risicobenadering. Hierbij bestaat het risiko uit de kans op een overstroming, gecombineerd met de schade die daardoor...master thesis 1996

Adriaens, F. (author), Van Rillaer, L. (author)The objective of the present work is to see whether the transport of sediment in a turbulent free surface flow can be studied with a new method of video image analysis, called the Two-Dimensional Particle Tracking Velocimetry. A slice of a two-dimensional turbulent flow in a laboratory flume is illuminated and particles are injected. After the...master thesis 1996

Eerkens, J.W. (author)In one-dimensional river modelling it is common to schematise the cross-section into a rectangular cross-section with a constant width. If a quasi-steady flow is assumed, the equilibrium longitudinal profile is known and unique: the bottom slope is constant and equals the water surface slope. However, numerical calculations at DELFT HYDRAULICS...master thesis 1996

Grasmeijer, B.T. (author), Sies, E.M. (author)Coastal changes occur mostly as a result of changes in sediment transport along the coast. If at cross-section A, the sediment transport is for any reason larger (or smaller) than at cross-section B, accretion (or erosion) will take place in between the two cross-sections. For prediction of coast-lines in the future, the prediction of the net...master thesis 1995

(author)In dit rapport wordt een drie-dimensionaal numeriek-wiskundig model ter berekening van het transport van zwevende en opgeloste stoffen in de Nederlandse kustwateren beschreven. Het belang van de modellering van zwevend stof en slib in drie dimensies wordt uiteengezet. Het model is een belangrijke schakel in een meer omvattende...report 1995

Janssen, C.M. (author)This literature review is part of the ongoing research on sand transport in oscillatory sheet-flow, as taking place at the coast during storms. Because sheet-flow corresponds to conditions of high shear stress, large amounts of sand are transported. Therefore it is an important part of the total sand transport (sheet-flow and suspended load)....report 1995

Van den Wollenberg, N.A.M. (author)The purpose of this study is to quantify the cross-shore sediment transport, caused by washover flows on barrier islands in general and on the Wai San Ting sandbar in Taiwan in particular. Washover transport on a barrier island is the transport of sediment across the sandbar f r om its steeper seaward face towards the gentler sloping landward or...master thesis 1994

Zhang, C. (author)In the last decade, several mathematical models for cross-shore sediment transport have been developed under the assumption that the instantaneous sediment transport is directly related to the instantaneous horizontal velocity just above the boundary layer. Although some models took beach slopes into account, most of the calibrated data were...report 1994

Voorendt, M. (author), Van de Graaf, J. (author)Results of sediment transport calculations are often necessary in solving practical coastal engineering problems. (Sediment transport due to waves and currents). Many transport formulae have been proposed in literature in the past. Selection of the proper one while solving a particular problem, is a difficult task for a coastal engineer. In...report 1994

Van Lieshout, M.C. (author)In this report a model has been derived to simulate morphological behaviour under tidal conditions. The model is based on the set of equations of motion and mass-balance for both water and sediment. The study focused on the underlying assumption that the kinematic response of the water movement on the bottom variation is much stronger than the...master thesis 1993

Janssen, C.M. (author)Cross-shore sediment transport is an important phenomenon in coastal engineering, which mainly accounts for the short-term changes in the coastline. To study on- and offshore transport the evolution of the beach profile is considered. For investigation of the beach profile small-scale physical models are often used. A problem in using a physical...master thesis 1993

Van 't Woud, A.J. (author)Bij het doen van voorspellingen op lange termijn met morfologische modellen heeft men te maken met sterk variërende randvoorwaarden (b.v. golfhoogte, getij stroming). Als men bijvoorbeeld het jaarlijkse sedimenttransport in een gebied langs de kust wil bepalen moeten eigenlijk al deze variaties van de randvoorwaarden, in de berekeningen worden...master thesis 1993
