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

Martens, D. (author)East Coast Park is a 15 km long coastal park along the southeast coast of Singapore. It is built on entirely reclaimed land and comprises a sandy shoreline. The beaches along this shoreline are formed due to the implementation of anthropogenic structures all along this stretch of coast through so-called headland control. These structures were...master thesis 2013

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

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

Van Rooijen, A. (author), Reniers, A. (author), Van Thiel de Vries, J.S.M. (author), Blenkinsopp, C. (author), McCall, R. (author)A one-dimensional hydrostatic version of the XBeach model (Roelvink et al., 2009) is applied to hindcast swash morphodynamics measured during an accretive, and an erosive tide at Le Truc Vert beach (France) in early spring 2008 (Masselink et. al, 2009; Blenkinsopp et al., 2011). Swash hydrodynamics are solved by applying the nonlinear shallow...conference paper 2012

Nabi, M. (author)Alluvial open channel beds often exhibit statistically periodic irregularities, known as dunes. Dunes have considerable effects on sediment transport and flow resistance. When growing during a flood, the dunes create more resistance and flood levels may rise significantly. Accurate prediction of dune properties therefore contributes to effective...doctoral thesis 2012

Pepping, C. (author)This master thesis aims to determine the best design option and the feasibility of an artificial sandy beach along the Old Boulevard of Batumi, Georgia. The coastline south of Batumi is affected by erosion problems. The coastal stretch between the port in the north and the Chorokhi River south of Batumi should be protected. In 2010 Alkyon...master thesis 2012

Dijkstra, J.T. (author)Aquatic plants –or macrophytes- are an important part of coastal, estuarine and freshwater ecosystems worldwide, both from an ecological and an engineering viewpoint. Their meadows provide a wide range of ecosystem services: forming a physical protection of the shoreline, enhancing water quality and harbouring many other organisms. Unfortunately...doctoral thesis 2012

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

Breugem, W.A. (author)Two experiments are performed in order to investigate suspended sediment transport in a turbulent open channel flow. The first experiment used particle image velocimetry (PIV) to measure the fluid velocity with a high spatial resolution, while particle tracking velocimetry (PTV) was used to measure the velocity of individual sediment particles....doctoral thesis 2012

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

Hopmans, R. (author), Van Kessel, L. (author), Lendering, K. (author), Oud, M. (author), Tromp, R. (author)The harbor of Surgidero de Batabano is a harbor that lies in the Gulf of Batabano in the South-Western part of Cuba. It serves as a connection between the main land of Cuba and the islands 'Isla de la Juventud' and Cayo Largo. The Batabano harbor suffers from sediment accretion. The accretion of sediment is harmful to port operations, since the...student report 2011

Sloff, C.J. (author)The DVR Toolbox is a modeling system developed to be used as an operational model for long-term morphological assessment of the Rhine branches in the Netherlands (10 to 50 years). The Toolbox consists of a 2D computational core (containing the Delft3D modeling system), a shell that controls input- and output, and a system for time/simulation...conference paper 2011

De Jongste, A.L. (author)The area of the Merwedes is a transition zone between a tide-dominated area and a river-dominated area. With increasing river discharge, the influence of river flow dominates in this part of the Rhine-Meuse Delta. The composition of the river bed of the Merwedes is also a transitional area, because of the presence of both sand and mud. It is...master thesis 2010

Chu, A. (author), Wang, Z.B. (author), De Vriend, H.J. (author), Stive, M.J.F. (author)A process-based model for the Yangtze Estuary is constructed to study the sediment transport in the estuary. The proposed model covers the entire tidal region of the estuary, the Hangzhou Bay and a large part of the adjacent sea. The dominant processes, fluvial and tidal, are included in the model. The calibration of the model against extensive...conference paper 2010

Ter Brake, M.C. (author), Schuttelaars, H.M. (author)In many tidal embayments, bottom patterns, such as the channel-shoal systems of the Wadden Sea, are observed. To gain understanding of the mechanisms that result in these bottom patterns, an idealized model is developed and analyzed for short tidal embayments. In this model, the water motion is described by the depth- and width-averaged shallow...journal article 2009
