Suleman, Mohammed (author)The increasing demand for rare minerals, such as lithium, cobalt, and copper, driven by the growth of the world population and the transition towards sustainable energy technologies, has become a pressing concern. These minerals are crucial for electrifying the transportation sector through electric vehicle production and are in high demand for...master thesis 2023

Elerian, M.F.A.I. (author)The depletion of terrestrial mineral deposits and the increasing demand for minerals are causing disruptions in the global supply chain. The shift towards renewable technologies requires significant quantities of metals used, for example, in the production of electric vehicles and wind turbines, putting additional strain on the supply chain. The...doctoral thesis 2023

Straathof, Judith (author)UV disinfection is an efficient way to inactivate chlorine resistant protozoan pathogens such as Cryptosporidium parvum and Giardia muris. In the United States, regulatory UV disinfection credit is typically granted when turbidity is <1 NTU. However, studies show turbidity does not correlate well with UV dose responses and partial...master thesis 2023

(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

Elerian, M.F.A.I. (author), van Rhee, C. (author), Helmons, R.L.J. (author)Renewable energy installations and energy storage solutions require significant quantities of critical raw materials such as nickel, cobalt and rare earth metals. The supply chains of these raw materials face many difficulties, such as the continuous decrease of mineral ore grades on land. In view of these complications, the motivation to...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

Wang, Jinyang (author), Dijkstra, Y.M. (author), de Swart, Huib E. (author)An estuarine turbidity maximum (ETM) results from various subtidal sediment transport mechanisms related to, e.g., river, tides, and density gradients, which have been extensively analysed in single-channel estuaries. However, ETMs have also been found in estuaries composed of multiple interconnected tidal channels, where the water and...journal article 2022

(author)Renewable energy installations and energy storage solutions require a significant amount of critical raw materials such as nickel, cobalt and rare earth elements. The supply chains of these raw materials face many challenges, e.g., these materials are often found at lower grades on land. These complications motivate the search for new resources....conference paper 2022

Wijmans, Yannick (author)Recently, deep-sea mining has acquired renewed interest from commercial companies due to a rise in the demand of minerals and metals. Deep-sea mining is focussed on different minerals and rare earth elements found in the oceans that are increasingly used in the manufacturing of goods and products related to renewable energy. In order to collect...master thesis 2021

Enthoven, dolf (author)Due to the increased demand for materials like cobalt and nickel, there is an interest to mine polymetallic nodules from the deep-sea. These nodules are abundantly distributed along the abyssal plains, e.g., the Clarion Clipperton Zone (CCZ) in the North East Pacific. These nodules lay spread on top of a seabed consisting of very fine clayey...master thesis 2021

Alhaddad, S.M.S. (author)Underwater slope failure is a common problem in the fields of geotechnical, dredging and hydraulic engineering, posing a major risk to submerged infrastructure and flood defences along coasts, rivers, and lakes. The term ‘flow slide’ refers to a specific, complex failure mechanism of underwater slopes, which occurs when a substantial amount of...doctoral thesis 2021

Elerian, M.F.A.I. (author), Alhaddad, S.M.S. (author), Helmons, R.L.J. (author), van Rhee, C. (author)The interest in polymetallic nodule mining has considerably increased in the last few decades. This has been largely driven by population growth and the need to move towards a green future, which requires strategic raw materials. Deep-Sea Mining (DSM) is a potential source of such key materials. While harvesting the ore from the deep sea by a...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

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...master thesis 2020

Bedón Vásquez, Andrea (author)Turbidity currents are common in the waters around the world. They can be caused by earthquakes, collapsing slopes or other geological disturbances. However, turbidity currents can also be caused by deep sea mining activities. Deep sea mining is done with special mining vehicles. There are three main operations within this mining vehicle:...master thesis 2020
