de Almeida Sousa, E. (author), Hofland, Bas (author)This study focuses on standing wave impacts on vertical hydraulic structures with relatively short overhangs. It addresses the demand for extended knowledge and loading prediction expressions for these structures. Based on laboratory experimental data from 146 tests, this paper works on two complementary objectives. Firstly, this study extends...journal article 2021

Verbeek, Merel C. (author), Labeur, R.J. (author), Uijttewaal, W.S.J. (author)The tidal flow between bridge pillars and through open barriers is a promising source of ocean energy which can be exploited using tidal stream turbines, as proven recently by operational demonstration plants. The aim of this study is to clarify the consequences for the power output of tidal turbines when placing them in a hydraulic structure...journal article 2021

Huijsman, Nino (author)The Netherlands has always been threatened by water. To protect flood-prone areas flood defenses have been constructed. To guarantee that they keep meeting the requirements systematic assessments take place. Since 2017, these assessments are performed according to the ‘Wettelijke beoordelingsinstrumentarium’ resulting in a safety judgment...master thesis 2020

Been, Stefan (author)Hydraulic structures can be prone to impulsive wave impact, which is a highly stochastic and uncertain process. This type of impact, defined by extreme pressure peaks and a very short duration, is not only caused by breaking waves, but also by non-breaking standing waves on structures with an overhang, such as culverts and steel gates. In this...master thesis 2020

de Heer, Danny (author)The weirs in the river Meuse reach their theoretical lifespan. The weirs were built in the early 1930s and now one is faced with a replacement task. Various studies have been carried out in recent years on the future of the weirs in the river Meuse. This concerns research into the entire weir system, different types of weirs and the way in which...master thesis 2020

Sleeuwaegen, Shannon (author)At this moment hydraulic structures are designed based on a simple method: the Dynamic Amplification Factor (DAF) method. This method does not consider the full dynamic interaction between the wave impacts, structure and water. The research project DynaHicS focusses on the dynamic behaviour of hydraulic structures, taking into account fluid...master thesis 2020

de Almeida Sousa, E. (author), Hofland, Bas (author)The applicability of pressure-impulse theory is evaluated for predicting wave impact loading magnitudes for non-breaking standing wave impacts on vertical hydraulic structures with relatively short overhangs. To this end, tests were carried out on a schematized but realistic configuration with low steepness regular wave impacts on a straight...journal article 2020

Meinen, Nadieh Elisabeth (author), Maria, Raphaël Daniël Johannes (author), Hofland, Bas (author), Jonkman, Sebastiaan N. (author)Vertical slender hydraulic structures such as sluices, navigation locks, or storm-surge barriers are often dynamically loaded by waves. For a safe and economic design, an accurate description of the wave loads is needed. A widely used formula for this purpose is the Goda–Takahashi wave load formula (GT). It was derived for the assessment of...journal article 2020

Chai, Xuzheng (author)Given its geographical location and history, water defense is of utmost importance for the Netherlands. Structural Health Monitoring (SHM) offers a promising approach for system identification of hydraulic structures in this water defense system. The aim of SHM is to set sensors on structures and use the monitored responses to identify...master thesis 2019

Zhang, Yuxi (author)Churchill Barriers, a series of four causeways in Orkney Islands, Scotland were constructed during Second World War and now serve and a critical link for South Ronaldsay and Burray to the Orkney Mainland. Due to their location and design, causeways are exposed to storm waves generated in the North Sea. During coastal storms, some waves are able...master thesis 2019

van den Kerkhoff, Roy-Matthieu (author)There is a growing demand for renewable sources of energy of which wave energy conversion is one. The Ocean Falls is an oscillating water column (OWC) system invented by BAM Infraconsult b.v. This system differs from conventional OWC systems since it includes a connection tube and an adjustable back wall. The OWC system is a resonance system for...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

Jonkman, Sebastiaan N. (author), Voortman, H.G. (author), Klerk, W.J. (author), van Vuren, S. (author)This article highlights recent developments in flood risk management in the Netherlands and presents approaches for reliability analysis and asset management for flood defences and hydraulic infrastructure. The functioning of this infrastructure is of great importance for the country as large parts of it are prone to flooding. Based on a...journal article 2018

Olsthoorn, thom (author)The reliability assessment of hydraulic structures, in primary water defences before 2017, is characterised by exceedance probabilities and implicit uncertainty. In January of 2017, the new water law enforces a change in the assessment of primary water defences. The water law requests a probability of flooding when assessing the safety...student report 2017

Multifunctional flood defenses protect areas against flooding, but<br/>serve other functions as well. Although these types of defenses<br/>can be seen almost everywhere, they pose special technical and<br/>governance challenges.<br/><br/>This book is about a unique interdisciplinary research program<br/>developed to tackle some of the issues...book 2017

van Oorschot, N. (author)The Netherlands is a country where people have to live with water, rather than fighting against it. This philosophy often requires interaction between infrastructure and waterways, where (hydraulic) structures are placed close to or even extending in the waterway, introducing the risk of ship collision. What makes this accidental load so...master thesis 2017

Scheltes, M.P. (author), Oosterwegel, M. (author), Elzinga, L. (author), Levinson, M.A. (author), Alkema, S.H. (author)Ho Chi Minh City is flooded on a regular basis due to the lack of flood protection. Plans have been made to protect the city from flooding in the future and therefore a barrier is built at Phu Dinh. This barrier needs to fulfil three requirements. Firstly it should protect HCMC against a flood, as well resulting from tidal waves as from peak...student report 2016
