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

Harms, Johan (author)Currently multiple projects investigate the effect of lowering the crest of groynes in the Dutch rivers with the aim to lower the backwater effect of groynes under high water levels. There is a major uncertainty however in the modelling of groynes, and therefore in the prediction of the effect of groyne lowering. Currently submerged groynes are...master thesis 2021

Hol, Tijs (author)Resistive RAM, or RRAM, is one of the emerging non-volatile memory (NVM) technologies, which could be used in the near future to fill the gap in the memory hierarchy between dynamic RAM (DRAM) and Flash, or even completely replace Flash. RRAM operates faster than Flash, but is still non-volatile, which enables it to be used in a dense 3D NVM...master thesis 2020

Huppes, Niek (author)After more than 85 years, the iconic Afsluitdijk is in need of a reinforcement. During the latest safety assessment of Rijkswaterstaat the dike did not meet the standards at two components; the amount of wave overtopping (>10 l/m/s) and armour stability. This research goes into detail about the overtopping on the Afsluitdijk. In the new...master thesis 2019

de Almeida Sousa, E. (author), Hofland, Bas (author), Jonkman, Sebastiaan N. (author)The study of wave impact physics and magnitudes are key for the design of vertical coastal hydraulic structures. This research addresses the study of standing wave impacts on vertical coastal hydraulic structures with a relatively short horizontal overhang, which is especially relevant for structures such as lock gates, sluice gates, dewatering...conference paper 2019

Krijgsman, Wiegert (author)In the noiseless case, the identification of a grey-box model can be posed as a feasibility problem, i.e. determining if existent - and if so - finding a parameter vector such that the parametric model equals the actual model (or its associated input-output data). Being that in this thesis we are interested in continuous-time grey-box...master thesis 2018

Chortis, Giorgos (author)Offshore wind farms are rapidly developing in Western Europe as an alternative means of clean energy. The foundation of wind-turbines in the shallow water of the Northern Sea is almost exclusively (over 87%) performed by short rigid monopiles, as an efficient and relatively cheap solution. Scour formation, meaning the soil removal around the...master thesis 2018

van den Berg, Ileen (author)The Xbloc<sup>Plus</sup> is a new type of single layer armour unit for breakwaters. The key difference between earlier single layer armour units is that the unit is not only placed in a regular grid, but also with a regular orientation. The main benefit of this is that it can directly be seen whether the unit is placed correctly. Additionally,...master thesis 2018

Jansen, Laura (author)Studying mangroves in the field can be very difficult; therefore it is in some situations better to model in a flume. The question is, to what extend are the situation in the field and the situation in the flume comparable with each other? This study focusses on reflection in the wave flume. Wave energy in a flume can be damped by placing a wave...master thesis 2018

van Zeben, Joris (author)During the last decade, the focus of offshore activities have shifted from oil and gas production to offshore wind farm creation to reach the clean energy targets set by different nations. Foundation requirements for offshore structures have shifted because of this. The monolithic nature of windmills allows the use of a single open-ended steel...master thesis 2017

de Almeida Sousa, Ermano (author)Coastal areas around the world have attracted settlements and human activities since the early stages of the history until nowadays. This has introduced continuous modifications to the natural characteristics of these coastal regions by means of coastal structures and engineering interventions. The design of such coastal structures has evolved...master thesis 2017

Marinov, Krasimir (author)Low-lying countries such as Belgium and the Netherlands are naturally susceptible to overtopping wave attacks. Coastal regions are therefore facing the threat of such events causing damage to dike-positioned structures and buildings. Research in this filed is often conducted using scaled-down 2D hydraulic physical models, which introduces so...master thesis 2017

Kyparissis, A. (author)Landfall operations are conducted for connecting an offshore pipeline with process facilities on the shore. During a landfall operation an offshore pipeline is pulled by means of a steel wire rope on the shore with a velocity of 7 cm/s. During this process the steel wire rope interacts with the soil located on the seabed and on the shore....master thesis 2016

Van der Linden, T.I. (author)In this thesis research is presented on the influence of multiple thin soft layers on the cone resistance and an attempt has been made to develop a correction factor from numerical and physical models. The presence of thin layers causes difficulties with determination of the liquefaction potential of sand deposits containing thin clay layers...master thesis 2016

Van Beek, V.M. (author)Backward erosion piping is an internal erosion mechanism during which shallow pipes are formed in the direction opposite to the flow underneath water-retaining structures as a result of the gradual removal of sandy material by the action of water. It is an important failure mechanism in both dikes and dams where sandy layers are covered by a...doctoral thesis 2015

Lioutas, A. (author), Smith, G.M. (author), Verhagen, H.J. (author)The scope of this research is to find an empirical formula to describe the distribution of wave overtopping in the region behind the crest. A physical model was set up in which irregular waves were generated. In order to find a formula which adequately describes the test observations, the influence of several parameters has been analysed. The...conference paper 2012
