Samboko, H.T. (author)The unavailability of consistent accurate river flow data is a significant impediment to understanding water resources availability, and hydrological extremes. This is particularly true for remote, difficult to access, morphologically active and therefore rapidly changing rivers. The state of global river discharge monitoring with respect to...doctoral thesis 2023

Dijkstra, Sam (author)Due to the rising sea level in combination with land subsidence there is a need to reinforce the dikes. The use of a crest element to increase the height of the dike is an effective and relatively cheap way to reinforce the dikes (Hogeveen, 2021). When a crest element is used, the jet generated by wave breaking on the dike slope impacts on the...master thesis 2023

Langeveld, Bram (author)Groynes are hydraulic structures commonly applied in the Dutch rivers. Depending on the water depth, groynes can be emerged or submerged. When a groyne is emerged, it has two main functions: maintaining the water depth in the main channel and preventing the river from eroding its bank. When the discharge in the river increases, the groynes...master thesis 2023

PYTHAROULIOU, ANGELINA (author)The rapid increase in global population and rising demands have resulted in a shortage of clean water, depleting several of the Earth's reservoirs, especially those that reserve fresh water. Just 0.007% of the water on Earth is used to hydrate and feed billions of people, as determined by the water balance of the planet. Water-stressed nations...master thesis 2023

Bodelier, Lotte (author)Many Dutch infrastructure assets were constructed in the first half of the 20th century and by considering an average design life time of roughly 100 years, a lot of these structures will reach the end of their designed life in the upcoming decades. This results in a large replacement and renovation challenge in the nearby future. Assessing the...master thesis 2023

Chan, Kou Wai (author)Due to an extraordinary precipitation event in July 2021, the Dutch government want to utilise the temporary flood barriers to reduce the impact caused by a flash flood event in the future. As a result, Water Board Limburg, Flood Proof Holland and Delft University of Technology made an agreement to conduct a physical experiment in Roermond on...student report 2023

de Almeida Sousa, E. (author)Hydraulic structures are crucial for navigation, water management and flood protection in low-lying coastal and delta regions. Their importance is expected to continue growing in the coming years, because of the consequences of climate change and the continuous development and urbanization of these regions combined with more strict safety...doctoral thesis 2023

(author), Armstrong Hall, Felix (author), Imasaki Afonso, Victoria (author), Moonen, Siirilotta (author), van Sabben, Pepijn (author)With combined efforts from water management, architectural and hydraulic engineering students, an interdisciplinary and resilient design is set up for the Paraná Delta. The design relates to all the current environmental, architectural and flood risk challenges - among others, as well as the potential issues in the future since the Paraná Delta...student report 2023

Verschoor, Bob (author)The world is heating up quickly. Since 1901, the temperature in the Netherlands has risen about twice as fast as the global average and the effects of climate change seem clearly noticeable. With sea levels rising and peak river discharges increasing an enormous pressure is mounting on the current Flood Protection Programme in the Netherlands...master thesis 2023

Lieftinck, Joris (author)The inner-city of Amsterdam contains a large network of vulnerable, historic quay walls. Most of these quay walls consist out of masonry gravity walls placed on wooden relieving floors and wooden foundation piles. Due to the changing surface loading conditions behind the wall and the degradation of the masonry and wooden structures over the last...master thesis 2023

Alhaddad, S.M.S. (author), Mehta, D. (author), Helmons, R.L.J. (author)We present an effective design of a hydraulic, polymetallic nodule collector, which fundamentally depends on the Coandă effect in harvesting nodules. The design was first developed based on 2D numerical simulations conducted using a computational fluid dynamics tool, ANSYS FLUENT. Following that, the design was tested in full-scale experiments,...journal article 2023

Shariati, Vahid (author), Roohi, Ehsan (author), Ebrahimi, Amin (author)The direct simulation Monte Carlo (DSMC) method, which is a probabilistic particle-based gas kinetic simulation approach, is employed in the present work to describe the physics of rarefied gas flow in super nanoporous materials (also known as mesoporous). The simulations are performed for different material porosities (0.5≤ϕ≤0.9), Knudsen...journal article 2023

Alhaddad, S.M.S. (author), Helmons, R.L.J. (author)To date, hydraulic collection is the most widely considered technology in polymetallic-nodule mining, since there is no direct contact between hydraulic collectors and ocean floor. To construct a hydraulic collector that results in the least sediment disturbance, it is critical to develop an insightful understanding of the interaction between...journal article 2023

(author), van der Meulen, Bas (author), Herget, Jürgen (author), Hulscher, Suzanne J.M.H. (author)Reconstructions of the most severe historic flood events contribute to improved quantification of design discharges corresponding to large return periods. Reducing the uncertainty of design discharges has a great significance in constructing proper flood defences to protect the hinterland from future flooding. However, reconstructions of the...journal article 2023

(author)Over the course of the last century, storm surge barriers have been built in several countries and proven to be successful in preventing flooding. However, the operation, reliability, and remaining life of these structures have come under increased pressure due to changing demands, intensified utilisation, and climate change. Yet, there is...journal article 2023

(author), Wang, Zhengbing (author)Hydraulic structures can be a promising place for tidal energy extraction due to the high flow velocities, easy access to the power grid and easy access for maintenance. However, quantification of the impacts of a tidal power plant in a hydraulic structure is not straight forward. In 2015 a pilot plant consisting of an array of five Tocardo...journal article 2023

Flessati, L. (author), Vecchia, Gabriele Della (author), Musso, Guido (author)Cement-bentonite cut-off walls are commonly employed in geoenvironmental applications to limit ground water flow and pollutant transport. The wide diffusion of this artificial material in the current practice is not only due to its low permeability, but also to its simplicity of use.
