Engel, Leander (author), Nijholt, Vincent (author), van de Wakker, Gerwin (author), Wesseling, Lucas (author), Winter, Theun (author)The Mekong Delta is facing some complicated challenges in the near future. Its geographical location and the fact that it is a delta result in low elevation levels which makes it vulnerable to inundation. This problem will only become bigger in the future due to the effects of climate change. To get funding from organisations like the world bank...student report 2023

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

Kranenburg, W.M. (author), Tiessen, Meinard (author), Blaas, Meinte (author), Van Veen, Nathalie (author)Around the world, estuaries have been partially or completely closed-off from the sea and their number may increase with rising sea levels. Concurrently, there is a trend to reintroduce seawater inflow into enclosed former estuaries for ecosystem improvement. This is also the case in the Haringvliet, a former estuary in the Rhine-Meuse Delta,...journal article 2023

Horemans, D.M.L. (author), Dijkstra, Y.M. (author), Tackx, Michèle (author), Meire, Patrick (author), Cox, Tom J.S. (author)Estuaries often show regions in which Chlorophyll-a (Chl-a) accumulates. The location and magnitude corresponding to such accumulation result from a complex interplay between processes such as river flushing, salinity, nutrients, grazing on phytoplankton, and the light climate in the water column. An example is the multi-annual evolution of...journal article 2023

Guo, Leicheng (author), Zhu, Chunyan (author), Cai, Huayang (author), Wang, Zhengbing (author), Townend, Ian (author), He, Qing (author)River discharge is known to enhance tidal damping and tidal wave deformation in estuaries. While the damping effect on astronomical tides has been well documented, river impact on tidal wave deformation and associated overtide generation (shallow water harmonics of one or more astronomical constituents, such as M<sub>4</sub>) remains...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

Iglesias, Sebastian (author)Nature-based initiatives have emerged as potential solutions to problems caused by saltwater intrusion in deltas found globally, but their successful implementation is enabled partly by a multi-stakeholder approach. The latter involves managing several parallel stakeholder objectives, which usually requires quantitative knowledge to understand...master thesis 2022

Wang, Jinyang (author), Dijkstra, Y.M. (author), de Swart, Huib E. (author)Net water transport (NWT) in estuaries is important for, for example, salt intrusion and sediment dynamics. While NWT is only determined by river runoff in single channels, in estuarine networks, it results from a complex interplay between tides and residual flows. This study aims to disentangle the various contributions of these physical...journal article 2022

(author)The estuarine turbidity maximum (ETM) in the Yangtze Estuary Delta (YED) is muddy by definition and lacks bottom undulations. However, since 2013, a remarkable change has occurred in the YED. Recent images detected by a multibeam echosounder system, SeaBat 7125, for the first time have confirmed widespread regions of subaqueous dunes in the...journal article 2022

Dijkstra, Y.M. (author), Schuttelaars, H.M. (author), Kranenburg, W.M. (author)Tidally averaged transport of salt in estuaries is controlled by various subtidal and tidal processes. In this study, we show the relative importance of various subtidal and tidal transport processes in a width-averaged sense. This is done for a large range of forcing and geometric parameters, which describe well-mixed to salt wedge estuaries...journal article 2022

Hanssen, J.L.J. (author), van Prooijen, Bram (author), Volp, Nicolette Dominique (author), de Vet, P.L.M. (author), Herman, P.M.J. (author)Although tidal flats appear homogeneous from a distance, morphological variations are found on various spatial scales. These are driven by physical and/or biological processes. In this paper, we consider the creeks that are present on fringing tidal flats and which are orientated approximately perpendicular to the main channel. To explain why...journal article 2022

Mi, Jie (author), Zhang, Min (author), Zhu, Zhenchang (author), Vuik, V. (author), Wen, Jiahong (author), Gao, Hongkai (author), Bouma, Tjeerd J. (author)The risk of coastal storm flooding is deteriorating under global warming, especially for the heavily urbanized deltaic cities, like Shanghai. The Nature-Based Flood Defense (NBFD), as an eco-friendly design alternative for hard infrastructure against coastal flooding, is gaining attention. Nevertheless, the vulnerability of saltmarsh due to...journal article 2022

Jongbloed, Hendrik (author), Schuttelaars, H.M. (author), Dijkstra, Y.M. (author), Donkers, Paul B. (author), Hoitink, Antonius J.F. (author)An idealized width-averaged model is employed to study the influence of wind stress on subtidal salt intrusion and stratification in well-mixed and partially stratified estuaries. We show that even in mild conditions, wind forcing can influence the estuarine salinity structure in a substantial way. By studying the role of wind forcing on...journal article 2022

River, tide and morphology interaction in a macro-tidal estuary with active morphological evolutionsXie, Dongfeng (author), Wang, Zhengbing (author), Huang, Junbao (author), Zeng, Jian (author)Understanding tidal dynamics in estuaries is essential for tidal predictions and assessments of sediment transport and associated morphological changes. Most studies on river-tide interaction ignored the influences of morphological evolutions under natural conditions such as the seasonal and interannual variations of river discharge. This...journal article 2022

Nijhuis, Loes (author)The Rhine-Meuse estuary is part of the Southwestern Delta area in the Netherlands. The nature present in the estuary suffered a great impact due to urbanization, as a natural delta transformed into an industrialized river, mainly due to port activities. Various parties decided to collaborate in order to return the tidal nature in the Rhine Meuse...master thesis 2021

Lin, Yu-Wen (author)Coastal areas and riverine cities accommodate the great majority of the world’s population, but they are extremely vulnerable to flooding risks. In the cities next to the Medway River estuary, the capacity to adapt to flood risks had been weakened by urban development and intense industrial usage. This degrading led to the loss of flood buffers...master thesis 2021
