Numerical modeling of hydrodynamic circulation in Lake Taihu

This study is aiming to improve the understanding of hydrodynamic circulation in large shallow lakes. The Lake Taihu, the third largest lake in east China, is picked up as the study area for three reasons. The basin of Lake Taihu is considered as the most populated and developed area as a backyard of Shanghai. Lake Taihu is a typical shallow...

The reset of a subtidal bar during an energetic event: Application to Le Truc Vert beach case (France)

A large number of beach morphologies across the world exhibits nearshore sandbars with complex 3D patterns. During large storms, these shapes disappear and the bars get to a certain extent alongshore uniform. This phenomenon is called a reset. Numerous studies have been conducted on the development of the bar shapes (3D) or on the cross-shore...

Erosive bar migration using density and diameter scaled sediment

Mobile bed scaling (for scales smaller than 1:1) does not allow for ideal similarity between all nondimensional parameters. This leads to an exaggerated presence of one process over another or the development of scale effects. The complexity of the surf zone makes it especially difficult to separate and quantify the effect of sediment scaling on...

Modelling the Giant Sandwaves of San Francisco Bay: A study on process based sandwave modelling, with an exploration on the mechanisms that results in the formation of these bedforms

Connected to the Pacific Ocean by the Golden Gate channel, the San Francisco Bay accommodates a widely spread field of sandwaves that show large spatial variations which are not yet fully understood. Insight into the formation of sandwaves is necessary to understand and predict the processes that control sand transport and sedimentation patterns...

Longshore sediment transport at Maasvlakte 2

Behaviour of a steep reclaimed profile exposed to a North Sea wave climate

The object of investigation of this study was the behaviour of reclaimed sand slopes when not constructed in an equilibrium state, but in a steeper profile. When constructing a steep slope, this slope will gradually become more flat and would periodically require sand nourishments. In this way part of the initial sediment placement would be...

Vergelijking UNIBEST-TC en DUROSTA: Twee tijdsafhankelijke dwarstransportmodellen

Voor de berekening van de grootte van het dwarstransport zijn momenteel in Nederland twee computermodellen in gebruik, te weten UNISEST-TC en DUROSTA. UNISEST-TC is ontwikkeld voor 'algemeen' gebruik, met gemiddelde condities. DUROSTA is ontwikkeld voor gebruik voor zware condities, waarbij hoge waterstanden kunnen optreden en een zware...

Strandhoofden gemodelleerd in Delft3D-RAM: Strandhoofden als instrument voor het regelen van het langstransport

Als gevolg van natuurlijke processen, zoals getijde en golven, is een kustomgeving voortdurend aan verandering onderhevig. Hierdoor is een zandige kust niet altijd stabiel en kan er op sommige plaatsen een achteruitgaande kustlijn worden aangetroffen. Indien zo'n achteruitgaande kustlijn een structureel karakter heeft, wordt dat vaak veroorzaakt...

The Teignmouth Model: Validation and evaluation of Delft3D-MOR with COAST3D Pilot campaign data

Computer models are commonly used to simulate the behaviour of the coast in response to natural processes (e.g. storms, extreme sea levels) or management plans (e.g. beach nourishment, channel dredging). The COAST3D project was initiated to improve and validate these numerical models. COAST3D stands for Coastal Study of ThreeDimensional Sand...
