van Asselt, Jasper (author), Bervoets, Hannah (author), Bloem, Celine (author), Kindermann, Vincent (author), Koopman, Ruben (author), Zwaan, Linde (author)The Mekong Delta in Vietnam is facing several challenges as a result of climate change. Among others, the effects include an increase in river discharge during the wet season, leading to river floods, and a decrease in river discharge during the dry season. The decrease in discharge results in a shortage of fresh water required for irrigation...student report 2023

de Groot, Hugo (author)The salinity profile in a coastal sea-river system is the result of balancing of salt transport due to mixing of the water by tides and the freshwater discharge from the river. When for example during times of drought freshwater discharge suddenly declines, the salinity in the river may increase significantly and threaten drinking water supplies...bachelor thesis 2023

Li, Irene (author)The Wadden Sea region is characterized as a diverse and contradictory area. On the one hand, it stands as the largest intertidal area globally, supporting a rich and diverse flora and fauna habitat showcasing nature’s power and allure. On the other hand, it is a landscape shaped by human habitation and extensive transformations, including...master thesis 2023

Hunter, Conor (author)This research study has investigated the effects of sills as a nature-based countermeasure to reduce saltwater intrusion within Rijnmond Drechtsteden. The effects of this measure have been assessed regarding its impact on port logistics and freshwater supply in the region. The heavily dredged New Waterway provides the vital open connection to...bachelor thesis 2023

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

(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

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

Leuven, Jasper R.F.W. (author), Niesten, Iris (author), Huismans, Y. (author), Cox, Jana R. (author), Hulsen, Lamber (author), van der Kaaij, Theo (author), Hoitink, A. J.F. (Ton) (author)Effects of sea-level rise (SLR) on future peak water levels in tidal deltas and estuaries are largely unknown, despite these areas being densely populated and at high risk of flooding. While the rates of SLR accelerate, many channels simultaneously experience channel deepening for navigation. With globally decreasing sediment supplies, most...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

Zhu, C. (author), van Maren, D.S. (author), Guo, Leicheng (author), He, Qing (author), Wang, Zhengbing (author)A decline of the fluvial sediment supply leads to coastal erosion and land loss. However, the fluvial sediment load may influence not only coastal morphodynamics but also estuarine hydrodynamics and associated saltwater intrusion. Previous studies revealed that suspended sediments influence estuarine hydrodynamics through various flow...journal article 2023

Hendrickx, G.G. (author), Antolínez, José A. Á. (author), Herman, P.M.J. (author)In recent years, coastal management has been facing new challenges: socio-economic growth and consequent climate change impose new boundary conditions pushing coastal systems towards unseen states. For adaptation and mitigation strategies as well as risk management, the resilience of systems to these projected changes must be tested and...journal article 2023

Slinger, J (author)The development of the bilateral Long Term Vision for the Scheldt Estuary between 1999 and 2001 reveals that it is possible to move from a history of conflict to cooperation in just two years. A retrospective, insider perspective is used to analyse the integrated three-layer hybrid modelling at the heart of this groundbreaking agreement. We...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.

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

(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
