Wengrove, M.E. (author), Henriquez, M. (author), De Schipper, M.A. (author), Holman, R. (author), Stive, M.J.F. (author)The Sand Engine is a mega-nourishment constructed in 2011 with the purpose of replenishing the surrounding southern Dutch coast by exploiting the strength of local alongshore currents for the next 20 years. Long term monitoring of the Sand Engine depends upon remote sensing coupled with in-situ measurements due to both its large spatial and...conference paper 2013

(author)The present paper describes an analysis of the morphological integrityof the multiple channel system (MCS) of the Western Scheldt estuary. The tidal flats and surrounding ebb and flood channels form morphological cells, and the entire MCS can be schematized as a chain of such cells. The major ebb and flood channels have lost their one time...conference paper 2001

Wang, Z.B. (author), Oost, A.P. (author)The Rif and the Engelsmanplaat form together a supra- to intertidal flat-complex at the fringe of the ebb-tidal delta and the back barrier area in the Frisian Inlet, located between the Dutch Wadden Sea Islands Ameland and Schiermonnikoog. The complex divides the Frisian Inlet into the Pinkegat Inlet in the west and the Zoutkamperlaag Inlet in...conference paper 2010

Lam, T.N. (author), Stive, M.J. (author), Verhagen, H.J. (author), Wang, Z.B. (author)Thuan An is a tidal inlet located in Vietnam in a tropical monsoon area. The inlet is very dynamic and variable under the influences of not only tides and waves from the sea but also flows and floods from upstream rivers. Therefore, morphodynamic behaviour of the inlet is very complicated and not well understood. Studies on inlet are also facing...conference paper 2006

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

Roelvink, D. (author), Den Heijer, C. (author), Van Thiel De Vries, J.S.M. (author)Land reclamations and island coasts often involve strongly curved shorelines, which are challenging to be properly modeled by numerical morphological models. Evaluation of the long term development of these types of coasts as well as their response to storm conditions requires proper representation of the governing physical processes. Not all...conference paper 2013

Li, W. (author)Hyperconcentrated flow/flood is a water-driven sediment transport phenomenon, which is characterized by high sediment concentrations between normal sediment-laden flow and debris/mud flow. In a hyperconcentrated flow, strong interactions exist between water flow, sediment, and river bed, which may not only change the flow rheological properties,...doctoral thesis 2014

Dastgheib, A. (author)The morphology of tidal basins includes a wide range of features developing along different spatial and temporal scales. Examples are shoals, channels, banks, dunes and ripples. Coastal engineers use their engineering tools to answer questions on the processes governing the short term (< decades) development of these morphological features....doctoral thesis 2012

Hibma, A. (author)In this research, the initial formation and long-term evolution of channel-shoal patterns in schematised basins is simulated using a model based on the software package Delft3D. The resulting channel-shoal patterns are validated with field observations, among which the Western Scheldt estuary. This has proven that a complex model is able to...doctoral thesis 2004

Aarninkhof, S.G.J. (author)Owing to the economic importance of seasonal fluctuations in beach width and the frequent implementation of local beach and shoreface nourishments, coastal managers and scientists increasingly demand coastal state information at smaller spatiotemporal scales. Advanced, automated video techniques provide the means to collect such high-resolution...doctoral thesis 2003

Blanckaert, K. (author)The migration rate of sharp meander bends exhibits large variance and indicates that some sharply curved bends tend to stabilize. These observations remain unexplained. This paper examines three hydrodynamic processes in sharp bends with fixed banks and discusses their morphological implications: secondary flow saturation, outer-banks cells, and...journal article 2011

Marciano, R. (author), Wang, Z.B. (author), Hibma, A. (author), De Vriend, H.J. (author), Defina, A. (author)We model branching channel patterns in short tidal basins with two methods. A theoretical stability analysis leads to a relationship between the number of channels and physical parameters of the tidal system. The analysis reveals that width and spacing of the channels should decrease as the slope of the bottom profile and the Shields parameter...journal article 2005

Hoffmans, G.J.C.M. (author)The general purpose of this research project is to model mathematically the local scour downstream of a structure (2-D). The model has to simulate the development of the scour as a function of the time. Basically two models are necessary namely a flow model and a morphological model. The latter model has to describe the bed and suspended load...report 1988

Talmon, A.M. (author), De Graaff, J. (author)A suspended sediment transport experiment in a straight flume with a mobile bed is reported. The bed topography is non-horizontal. The flow is steady. Due to an obstruction in the entrance a steady bed oscillation is generated. The bed topography is measured by means of manual bed soundings (by Delft Hydraulics). Suspended sediment...report 1991
