Sun, J. (author), van Prooijen, Bram (author), Wang, Xianye (author), Zhao, Zhonghao (author), He, Qing (author), Wang, Zhengbing (author)Creeks are essential for salt marshes by conveying water and sediment through this geomorphic system. In this paper, we investigate the mechanisms that determine the residual sediment flux using measurements conducted in tidal creeks in salt marshes of the Yangtze Estuary. A main creek and a secondary creek were studied to explore whether the...journal article 2024

Pearson, S.G. (author), Elias, Edwin (author), van Prooijen, Bram (author), van der Vegt, H. (author), van der Spek, A.J.F. (author), Wang, Zhengbing (author)Ebb tidal deltas (ETDs) are highly dynamic features of sandy coastal systems, and coastal management concerns (e.g., nourishment and navigation) present a pressing need to better describe and quantify their evolution. Here we propose two techniques for leveraging the availability of high-resolution bathymetric surveys to generate new insights...journal article 2022

(author)Estuaries and coasts can be conceptualized as connected networks of water and sediment fluxes. These dynamic geomorphic systems are governed by waves, tides, wind, and river input, and evolve according to complex nonlinear transport processes. To predict their evolution, we need to better understand the pathways that sediment takes from source...conference paper 2021

(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...journal article 2021

Pearson, S.G. (author), van Prooijen, Bram (author), Poleykett, Jack (author), Wright, Matthew (author), Black, Kevin (author), Wang, Zhengbing (author)Sediment tracer studies use uniquely identifiable particles to track the pathways and fate of individual sand or silt grains in marine environments. These techniques are best applied to assess connectivity between potential sediment sources and sinks, such as between a sand nourishment and an ecologically sensitive area. Significant challenges...journal article 2021

Gundlach, Jannek (author), Zorndt, Anna (author), van Prooijen, Bram (author), Wang, Zhengbing (author)In this paper, we unravel the mechanisms responsible for the development of the two-channel system in the Outer Weser Estuary. A process-based morphodynamic model is built based on a flat-bed approach using simplified boundary conditions and accelerated morphological develop-ment. The results are analyzed in two steps: first, by checking for...journal article 2021

(author)Intertidal shoals are pronounced morphological features found in many estuaries worldwide. Apart from maintaining an ecologically unique intertidal environment, shoals also protect adjacent dyke systems by attenuating waves. The fate of sandy shoals under anticipated sea level rise (SLR) scenarios is underexplored. The current research...journal article 2021

van Weerdenburg, R.J.A. (author), Pearson, S.G. (author), van Prooijen, Bram (author), Laan, Stendert (author), Elias, Edwin (author), Tonnon, Pieter Koen (author), Wang, Zhengbing (author)Multiple tidal inlet systems like the Wadden Sea have long been considered as separated basins, bordered by so-called tidal divides. Recently, it was however shown that fluxes of water and sediment occur over the borders of these basins, especially during wind events. In this paper, the wind-driven fluxes over these borders and the residual...journal article 2021

Lin, J. (author), van Prooijen, Bram (author), Guo, Leicheng (author), Zhu, C. (author), He, Qing (author), Wang, Zhengbing (author)Channel deepening often triggers positive feedback between tidal deformation, sediment import and drag reduction, which leads to the regime shift in estuaries from low-turbid to hyper-turbid state. In this study, a transition in profiles of suspended sediment concentration (SSC) is hypothesised by including a positive feedback loop of...journal article 2021

(author)A large-scale field campaign was carried out on the ebb-tidal delta (ETD) of Ameland Inlet, a basin of the Wadden Sea in the Netherlands, as well as on three transects along the Dutch lower shoreface. The data have been obtained over the years 2017-2018. The most intensive campaign at the ETD of Ameland Inlet was in September 2017. With this...journal article 2020

(author), Wang, Zhengbing (author)Dredging of navigation channels in estuaries affects estuarine morphology and ecosystems. In the Western Scheldt, a two-channel estuary in the Netherlands, the navigation channel is deepened and the sediment is relocated to other parts of the estuary. We analyzed the response of an intertidal flat to sediment disposals in its adjacent channel...journal article 2020

Lin, J. (author), He, Qing (author), Guo, Leicheng (author), van Prooijen, Bram (author), Wang, Zhengbing (author)Accurate measurement of suspended sediment concentration (SSC) in highly turbid environments has been a problem due to optical or acoustic signal saturation and attenuation. The saturation returns a limited measurement range, and the attenuation raises an ambiguity problem that a low optical or acoustic output could mean a low or a high SSC....journal article 2020

(author), Wang, Zhengbing (author)Hydrodynamic forces on intertidal flats vary over a range of temporal and spatial scales. These spatiotemporal inhomogeneities have implications for intertidal flat morphodynamics and ecology. We determine whether storm events are capable of altering the long-term morphological evolution of intertidal flats, and unravel the contributions of...journal article 2020

(author), Wang, Zhengbing (author)We apply a 2-D horizontal process-based model (Delft3D) to study the feedback mechanisms that control the long-term evolution of a fringing intertidal flat in the Western Scheldt Estuary. The hydrodynamic model is validated using a comparison with measurements on the intertidal flat and the sediment transport module is calibrated against long...journal article 2018
