van Beek, Mats (author)In dredging and land reclamation, there are growing economic and environmental pressures to make beneficial use of fine-grained/cohesive soils. Due to these pressures, there is renewed interest in researching ways to optimise the beneficial use of fine-grained soils in dredging and reclamation.<br/>Stiff cohesive clayey soils soil break up into...master thesis 2023

Köroğlu, Ege (author)In this Masters thesis, the dynamics of pipes conveying pulsating flow are investigated. The initial-boundary value problem associated with the linear beam equations of motions governing the pipe system is derived using the principles of Lagrangian mechanics. In this thesis, the fluid flow is assumed to have a small velocity with harmonic time...master thesis 2023

van Woudenberg, Jaïr (author)The sea level is rising, possibly by one meter, by the end of this century. The Netherlands is preparing for this scenario through Kennisprogramma Zeespiegelstijging (KP-ZSS). One of the goals is to determine the hydraulic effects of sea level rise (SLR) on the current system. For the flood risk analysis within<br/>KP-ZSS, the current strength...master thesis 2023

Coevert, Steven (author)The Netherlands is a country that is being threatened by water, both from the rivers and from the sea. The Dutch have built dikes to keep their lands from inundation. To ensure the strength and stability of these dikes, they are being assessed on the basis of several failure mechanisms. One of these failure mechanisms is...master thesis 2023

Fontijn, Jasper (author)Subsea rock installation is an offshore engineering process where rocks are placed on the seabed as protection of cables and pipelines and as scour protection. The inclined fallpipebis a new piece of equipment specifically designed to install rocks close to submerged structures. This thesis investigates the processes of the rock flow in and...master thesis 2023

Stokman, Charlotte (author)The energy market is growing and noise regulations for offshore foundation pile installation grow stricter. New initiatives arise to comply with the ongoing developments in the field, such as the BLUE Piling Technology under development by IQIP. Its features are presented as reduced underwater noise levels during installation, which is attibuted...master thesis 2023

van Dijk, Sanne (author)The applicability of the Sellmeijer design rule to Limburg dike sections near Well, Hout-Blerick, Buggenum, and Thorn was investigated in this thesis. This was accomplished by building a finite element numerical model, in COMSOL Multiphysics, to assess the piping in the hydrogeological systems of the research locations. The proposed model is...master thesis 2023

NATHANAEL, KONSTANTINOS (author)Despite the technological improvements in the dredging industry in the last decades, there are components that have not been investigated accordingly. One of them is the bow coupling bend pipe which can be found on trailing suction hopper dredgers. In contrast to most pipelines, the specific bend pipe is not only a means of transport for the...master thesis 2023

Makris, K. (author), Langeveld, J.G. (author), Clemens-Meyer, François H.L.R. (author), Watts, Joanna (author), Begum, Hasina (author), Horoshenkov, Kirill V. (author)This article explores the potential of vibro-acoustics to detect physical ageing of plastic pipes. For this purpose, two different topics are combined: the ability of vibro-acoustics to estimate the storage modulus of a plastic pipe, and the sensitivity of the estimated storage modulus to changes due to ageing. Concerning the first topic, a...journal article 2023

Pol, J.C. (author), Kindermann, P.E. (author), van der Krogt, M.G. (author), van Bergeijk, Vera M. (author), Remmerswaal, G. (author), Kanning, W. (author), Jonkman, Sebastiaan N. (author), Kok, M. (author)Structural reliability analysis often considers failure mechanisms as correlated but non-interacting processes. Interacting failure mechanisms affect each others performance, and thereby the system reliability. We describe such interactions in the context of flood defenses, and analyze under which conditions such interactions have a large impact...journal article 2023

Buist, J.F.H. (author), Sanderse, Benjamin (author), Dubinkina, Svetlana (author), Oosterlee, C.W. (author), Henkes, R.A.W.M. (author)The pressure-free two-fluid model (PFTFM) is a recent reformulation of the one-dimensional two-fluid model (TFM) for stratified incompressible flow in ducts (including pipes and channels), in which the pressure is eliminated through intricate use of the volume constraint. The disadvantage of the PFTFM was that the volumetric flow rate had to...journal article 2023

Blokland, M. (author), van der Mei, R. D. (author), Pruyn, J.F.J. (author), Berkhout, J. (author)Piping systems are common in many architectures and designing such systems is often a complex task. Design automation of piping systems is therefore a universal research subject. Nonetheless, these piping systems are often still designed by hand as a result of their complexity. Consequently, costs associated with piping design are high,...journal article 2023

Hirtreiter, E.J. (author), Schulze Balhorn, L. (author), Schweidtmann, A.M. (author)Developing Piping and Instrumentation Diagrams (P&IDs) is a crucial step during process development. We propose a data-driven method for the prediction of control structures. Our methodology is inspired by end-to-end transformer-based human language translation models. We cast the control structure prediction as a translation task where...journal article 2023

Pol, J.C. (author)Structural flood protection systems such as levees are an important component in flood risk reduction strategies. Levees can fail through various failure mechanisms; this thesis focuses on the mechanism Backward Erosion Piping (BEP) which occurs when a sandy levee foundation is eroded by groundwater flow. To assess whether a levee's reliability...doctoral thesis 2022

Pleij, Lodewijk (author)The soil-grout interface friction was measured to be in between 0.0 [kPa] and 14 [kPa]. To measure this friction, a special research method was invented that enabled a tunnel to be recreated. With this setup, any formation could be used. The formation could be created with a hole in the middle which simulated a borehole. Next, by filling and...master thesis 2022

Pol, J.C. (author), Kanning, W. (author), van Beek, Vera M. (author), Robbins, Bryant A. (author), Jonkman, Sebastiaan N. (author)Backward erosion piping (BEP) is a form of internal erosion which can lead to failure of levees and dams. Most research focused on the critical head difference at which piping failure occurs. Two aspects have received less attention, namely (1) the temporal evolution of piping and (2) the local hydraulic conditions in the pipe and at the pipe...journal article 2022

Wang, Jianyong (author), Yang, Jun (author), Gong, Jishuang (author), Zhao, Chunrong (author), Hooman, K. (author)Supercritical flow through a horizontal pipe leads to a non-uniform peripheral wall temperature distribution even when the wall heat flux is kept constant and uniform. This is attributed to lower heat transfer coefficient at the top section where the denser fluid tends to sink. Hence, to obtain a uniform wall temperature, a designed wall...journal article 2022
