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...journal article 2023

Zhu, Chunyan (author), Zhang, Yuning (author), van Maren, D.S. (author), Xie, Weiming (author), Guo, Leicheng (author), Wang, Xianye (author), He, Qing (author)The sediment load in the Yangtze River downstream of the Three Gorges Dam (TGD) has substantially declined in recent decades. The decrease is more profound below the TGD, e.g., a 97% decrease at Yichang, compared with that at the delta apex, 1200 km downstream, e.g., a 75% decrease, implying along-river sediment recovery. Two large river...journal article 2023

(author), Gerkema, Theo (author), Schulz, Kirstin (author)An extensive field campaign, the Ems-Dollard Measurements (EDoM), was executed in the Ems Estuary, bordering the Netherlands and Germany, aimed at better understanding the mechanisms that drive the exchange of water and sediments between a relatively exposed outer estuary and a hyper-turbid tidal river. More specifically, the reasons for the...journal article 2023

(author), Wang, Zhengbing (author)Many estuaries and tidal basins are strongly influenced by various human interventions (land reclamations, infrastructure development, channel deepening, dredging and disposal of sediments). Such interventions lead to a range of hydrodynamic and morphological responses (a changing channel depth, tidal amplitude and/or suspended sediment...journal article 2023

Zhou, Z. (author), Ge, Jianzhong (author), van Maren, D.S. (author), Gu, Jinghua (author), Ding, Pingxing (author), Wang, Zhengbing (author)The Krone–Partheniades (K-P) framework has been used for decades to quantify and analyze the sediment exchange at a water–bed interface. Measuring the erosion and deposition parameters that are part of this framework requires time-consuming field observations. Additionally, the erosion parameters are measured independently of deposition...journal article 2022

Tas, S.A.J. (author), van Maren, D.S. (author), Reniers, A.J.H.M. (author)Cheniers are ridges consisting of coarse-grained sediments, resting on top of the fine sediment that forms the otherwise muddy coast. In this paper, we use Delft3D to explore how cheniers are formed through wave winnowing. We identify three phases of chenier development: (a) a winnowing phase, during which mud is washed out of the seabed...journal article 2022

Tas, S.A.J. (author), van Maren, D.S. (author), Helmi, Muhammad (author), Reniers, A.J.H.M. (author)A chenier is a beach ridge, consisting of sand and/or shells, overlying a muddy substrate. In this paper, we explore the cross-shore dynamics of cheniers in their ‘active’ phase, i.e. the phase between their formation and their landing on the shore and can no longer be reached by daily wave and tidal influences. While cheniers described in...journal article 2022

(author)Deltas worldwide are at risk of elevation loss and drowning due to relative sea-level rise. Management strategies to restore or enhance sedimentation on delta plains, Sedimentation-Enhancing Strategies (hereafter SES), are now being pursued in many deltas but there has been limited cross-disciplinary and cross-delta review. Here we compare 21...journal article 2022

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,...journal article 2022

(author), Bijleveld, A. I. (author), Wang, Zhengbing (author)The sediment composition of the seabed governs its mobility, hence determining sediment transport and morphological evolution of estuaries and tidal basins. Bed sediments often consist of mixtures of sand and mud, with spatial gradients in the sand/mud content. This study aims at increasing the understanding of processes driving the sediment...journal article 2022

Zhu, C. (author), Guo, Leicheng (author), van Maren, D.S. (author), Wang, Zhengbing (author), He, Qing (author)Estuarine tidal dynamics are influenced by changes in morphology and friction. In this work, we quantified changes in tidal damping in the Yangtze Estuary and explored the impact of morphology and friction using a numerical model. In-depth analyses of tidal data reveal a strong reduction in tidal damping from 1990 to 2010, followed by a...journal article 2021

Colina Alonso, A. (author), van Maren, D.S. (author), Elias, E. P.L. (author), Holthuijsen, S. J. (author), Wang, Zhengbing (author)Human interventions and climate change can heavily influence the large-scale morphological development of tidal basins. This has implications on sediment management strategies, as well as ecological and recreational purposes. Examples of heavily impacted tidal basins are those in the Western Dutch Wadden Sea. The closure of a large sub-basin...journal article 2021

However, our understanding of lateral transport of suspended sediment during high and low water slack is still fairly limited, especially in engineered estuaries.

Zhu, C. (author), van Maren, D.S. (author), Guo, Leicheng (author), Lin, J. (author), He, Qing (author), Wang, Zhengbing (author)An estuarine turbidity maximum (ETM) is a region of elevated suspended sediment concentration (SSC) resulting from residual transport mechanisms driven by river flow, tides, and salinity-induced density gradients (SalDG). However, in energetic and highly turbid environments such as the Yangtze Estuary, SedDG may also substantially contribute...journal article 2021

Tas, S.A.J. (author), van Maren, D.S. (author), Reniers, A.J.H.M. (author)Cheniers are important for stabilising mud-dominated coastlines. A chenier is a body of wave-reworked, coarse-grained sediment consisting of sand and shells overlying a muddy substrate. In this paper we present and analyse a week of field observations of the dynamics of a single chenier along the coast of Demak, Indonesia. Despite relatively...journal article 2020

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 ...journal article 2020
