For centuries humanity has been engineering the second largest river system in the Netherlands, the river Meuse system. This resulted in improvements for the shipping and water safety functions, but simultaneously has had a negative impact on other functions of the river Meuse system. Nature and water quality, for example, degraded due to the...

The combination of continuous sea level rise, and more frequent extreme river discharges will become a rapidly developing problem for the Rhine-Meuse delta over the course of the next century. The current Dutch delta management policy mostly revolves around the consistent improvement of the existing dikes to account for the increasing water...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

On 29 October 2012 hurricane Sandy hit the coast of New York City. This category 1 hurricane had a devastating effect: large parts of the city were flooded and the city was out of business for several days. An estimated total damage of $41.9 billion had occurred of which $5 billion in account of the metro system. The largest damage was to the...

This thesis describes the development and testing of a methodology to use information collected by volunteers and technicians on the status of hydraulic structures, applicable for day-to-day risk management. The study was performed in the northeastern Italian Alps of the Friuli Venezia Giulia region. A decision support method was developed and...
