Tidal amplification and river capture in response to land reclamation in the Ganges-Brahmaputra delta

van Maren, D.S. (author), Beemster, J. G.W. (author), Wang, Zhengbing (author), Khan, Z. H. (author), Schrijvershof, R. A. (author), Hoitink, A. J.F. (author)

At a global scale, intertidal areas are being reclaimed for agriculture as well as urban expansion, imposing high human pressure on the coastal zone. The Ganges-Brahmaputra Delta (GBD) is an exponent of this development. In this delta, land reclamation accelerated in the 1960's to 1980's, when polders were constructed in areas subject to...

Morphodynamic modeling and morphological upscaling in a fine sediment system

Mathew, R. (author), Winterwerp, J.C. (author)

Sediment mobility and memory effects distinguish transport and morphodynamics in fine sediment settings from sandy settings. This paper focuses on the morphodynamic modeling of fine sediment systems, and an adaptation of modeling procedures more commonly used in sand-dominated systems. An extensive dataset of short-term transport and...

Feedback Effects of Sediment Suspensions on Transport Mechanisms in an Estuarine Turbidity Maximum

Zhu, C. (author), van Maren, D.S. (author), Guo, Leicheng (author), Lin, J. (author), He, Qing (author), Wang, Zhengbing (author)

The mechanisms controlling the formation of an estuarine turbidity maximum (ETM) in estuaries have been extensively investigated, but one aspect that has received much less scientific attention is the role of high suspended sediment concentrations in combination with tidal asymmetry in ETM formation. Particularly in highly turbid estuaries,...

A biophysical model for seedling establishment in mangrove forests

Gijsman, R. (author), Horstman, E.M. (author), Willemsen, P.W.J.M. (author), Swales, A. (author), Wijnberg, K.M. (author)

Mangrove seedling establishment is crucial to the long-term development of mangrove forests. This study incorporates a process-based approach for seedling establishment in a process-based hydrodynamic model. The biophysical model is used to simulate seedling establishment in the Firth of Thames estuary (New Zealand). The results are compared to...

An investigation on salt marsh resilience to sea-level rise and increased storm intensity

Pannozzo, N. (author), Leonardi, N. (author), Carnacina, I. (author), Smedley, R. (author)

Salt marshes are ecosystems with significant economic and environmental value. They provide numerous services, including nutrient removal, habitat provision and carbon sequestration (Barbier et al., 2011). They are also widely recognised as nature-based solutions for coastal defence due to their ability to buffer storm waves (Leonardi et al.,...

Analysis of nonlinear ship-induced 3d wave fields using nonlinear fourier transforms

Zhang, H. (author), Wahls, S. (author), Brühl, M. (author)

In the past decade, observations in the German estuaries such as the rivers Elbe and Weser show increasingly serious damage to bank protection structures (groins and revetments). This damage is caused mainly by waves induced by the passing of big container ships in the shallow and narrow maritime waterways. These ship-induced 3D wave fields...

The effect of storms on fine sediment dynamics in the Dutch Coastal Zone

Schmidt, Anneliese (author)

The North Sea is a heavily used area, with wind parks, shipping routes, fishing, sand mining, and many future constructions planned. The Dutch Coastal Zone, the area of the North Sea containing the Dutch coast, is home to several natural areas, alongside extensive human-built flood defenses. Maintaining balance between these areas requires that...

Characterizing the Composition of Sand and Mud Suspensions in Coastal and Estuarine Environments Using Combined Optical and Acoustic Measurements

Pearson, S.G. (author), Verney, Romaric (author), van Prooijen, Bram (author), Tran, Duc (author), Hendriks, H.C.M. (author), Jacquet, Matthias (author), Wang, Zhengbing (author)

Quantifying and characterizing suspended sediment is essential to successful monitoring and management of estuaries and coastal environments. To quantify suspended sediment, optical and acoustic backscatter instruments are often used. Optical backscatter systems are more sensitive to mud particles (<63 μm) and flocs, whereas acoustic...

On the behaviour of fine sediment in settling basins: Improving the understanding and prediction of return water quality assessments by a comparative modelling study

Veenman, Tjerk (author)

In this study, the behaviour of fine sediment in settlings basins has been investigated. The understanding and prediction of return water quality assessments is improved by a comparative modelling study. Settling basins are required to decrease the exhaust of fine sediment particles when dredging and reclaiming land. Fine sediment particles can...

Fine Sediment Pathways and Connectivity in San Francisco South Bay

van Gijzen, Laurie (author)

Introduction <br/>San Francisco Bay is one of the largest estuaries of the US Pacific Coast with an area of 4000 km2. It consists of two hydrologically distinctive sub-embayments North Bay and South Bay. South Bay is unique as it does not experience the freshwater flushing typical for estuaries. It experiences the largest freshwater input during...

Formation of the Zeebrugge coastal turbidity maximum: The role of uncertainty in near-bed exchange processes

van Maren, D.S. (author), Vroom, J. (author), Fettweis, M. (author), Vanlede, J.D.S.M. (author)

Despite availability of a large amount of observational data and modelling studies, the mechanisms maintaining the Turbidity Maximum in the Belgian-Dutch coastal zone around the port of Zeebrugge (Belgium) are insufficiently understood. In order to better understand the dynamics of this turbidity maximum we examine the role of baroclinic ...

Floodplain Land Cover and Flow Hydrodynamic Control of Overbank Sedimentation in Compound Channel Flows

Juez, Carmelo (author), Schärer, C. (author), Jenny, H. (author), Schleiss, A. J. (author), Franca, M.J. (author)

Overbank sedimentation is predominantly due to fine sediments transported under suspension that become trapped and settle in floodplains when high-flow conditions occur in rivers. In a compound channel, the processes of exchanging water and fine sediments between the main channel and floodplains regulate the geomorphological evolution and are...

On physical oceanography of the Santos Estuary

Tomasoni Speranzini, Belisa (author)

This thesis investigates the origins of large sedimentation volumes in the Port of Santos, São Paulo - Brazil. The port is located in the Santos - São Vicente estuarine system, delimited by scarps and subject to intense rainfall. The terminals are placed inside the estuary and their access is provided by a 24 km long channel with mean depths of...

Multiple scales of suspendend sediment dynamics in a complex geometry estuary

Achete, F.M. (author)

Many estuaries are located in urbanized, highly engineered environments. Cohesive sediment plays an important role because of its affect on estuarine health and ecology. An important ecological parameter is the suspended sediment concentration (SSC) translated into turbidity levels and sediment budget. Veel estuaria zijn gelegen in...

This study presented in this book investigates micro- and macro- scale physical processes of a large-scale fine sediment estuarine system with a moderate tidal range as well as a highly seasonal-varying freshwater inflow. Based on a series measured, experimented and modeled results, the research highlights that (i) along-channel fresh-salt...

Sedimentation and Flood assessment for the expansion of Kingston Harbour, Jamaica

Kerssens, P. (author), Verreijken, K. (author), Vermerris, P. (author), Wijs, J. (author)

Student project report, in cooperation with Smith-Warner International Ltd. (SWIL), Kingston, Jamaica. At this moment the shipping channels in Kingston Harbour, Jamaica, slowly accrete. When the harbour is expanded, the local and global sediment transport is likely to change. During this project it is investigated whether these changes are...

Fine sediment transport near coral reefs islands in the Singapore Strait

Dian Zoelaeha, B. (author)

The objective of this study is to determine large scale of fine sediment transport near coral reefs islands in the Singapore Strait. Coral reefs in the Singapore Strait face great pressure due to high sedimentation and turbidity, which cause decreasing of light penetration and of environment quality for the coral growth. Sedimentation and high...
