Jansen, Martijn (author)
Sea level rise and land subsidence increasingly put more pressure on Dutch flood protections. Additional to regular dike reinforcements, new, more nature-based, solutions are considered, such as a double dike system (DDS). Such system, consisting of two parallel dikes in combination with an interdike area in the form of a salt marsh, offers the...

Due to accelerating climate change, which entails more extreme storm conditions and exponential sea level rise, the protective function of our dikes and levees is under growing pressure. The presence of so-called forelands (e.g., beach, mudflat, and tidal marsh) are promising Nature-based Solutions to reduce the probability of dike failure and...

The Kampereiland is an island located at the south eastern part of the IJsselmeer in the middle of the Netherlands. This island serves a purpose to lower water levels in the IJssel- and Vechtdelta during high water, by being inundated. This inundation is meant to result in lower water levels in the IJssel near Kampen. However, the flooding of...

Embankments are one of the key aspects of flood protection programs. As the sea levels are expected to rise the coming decades coastal protection is becoming increasingly important. To better prepare for the future, increased understanding of embankment breaching is desired. An area of embankment breaching that has been relatively left untouched...

This master thesis is about the positive effects of river system behaviour along the river IJssel. Due to failure of the flood defences along the IJssel, the protected areas will flood and water will flow out of the river. The discharge in the river will decrease and thus the water level at the downstream ends of the river will also decrease....

This master thesis investigates the aerodynamic response of the Hyperloop breach failure scenario. Using a scaled physical test setup, the air pressure inside a Hyperloop tube is lowered to 10 mbar, emulating Hyperloop conditions. By opening a breach hole inside the tube, air will flow into the tube due to the pressure difference with the...

In the past decade, the world has experienced numerous severe and impactful data breaches, without indications of this development slowing down. Even worse, research has shown data breaches are still waiting to happen. The occurrence of a data breach has consequences for several involved parties and for society in general. It is therefore only...

As a low-lying city, Shanghai faces threats from typhoon and spring tide under the condition of climate change and land subsidence. With high water level at the toe, the sea embankment is likely to be overtopped and breached, finally resulting in inundation inland.  The objective of this research is to study climate change...

Verbeek, Bram (author)
Dikes constructed of a sand core, clay cover and natural vegetation as (landside) slope protection are common flood defence structures in the Netherlands. The design parameters, such as the crest height of dikes, are determined through risk assessment to reduce the remaining probability of a failure mechanism, such as overflow. Little is known...

The Netherlands has always been in close proximity to water, whether its rivers or the sea. This proximity to water and the need for land to settle and farm, led to vast amounts of land reclamation by constructing dykes along the water features to prevent flooding of the new earned land. This newly reclaimed land started to subside over the...

When dredging close to underwater sand slopes, steep slopes might form. In dense sand with low permeability this might lead to the so-called breaching process. The creation of a steep underwater slope marks the beginning of a breaching process. <br/>Pore volumes of densely packed sand tend to increase during shear deformations. This effect is...

An underwater slope can collapse by liquefaction, wedge failure or breaching. Breaching is the most unknown process and has a low predictability. Dredge mining is strongly influenced by the breaching process. If breaching can be accurately predicted, the efficiency of the dredging production can be maximised.It is the objective to know what...

Peelen, G.P. (author)
The stability of subaqueous slopes is often studied to determine the probability of failure of hydraulic structures. Slope failures have been widely studied to increase the understanding of this complex failure mechanism. However, after a failure it is often hard to figure out the type of failure mechanism: static liquefaction or breach flow....

Ponsioen, L.A. (author)
This thesis discusses the breach initiation processes at the land-side slope of a dike, due to overflow and wave overtopping. To date still little is known about the actual failure process of land-side slope covers. Therefore, starting in 2007, numerous wave overtopping experiments have been executed in The Netherlands and Belgium using a wave...

Foortse, B. (author)
People all around the world live and work in low-lying areas. Low-lying areas have to be protected against high water levels in rivers and at sea by a water protection system (e.g. by dunes, dikes and barriers). Dikes are an important component within water protection systems. Generally, dikes are described as elongated naturally occurring or...

At the moment, for determining the safety of the dike ring areas around the IJsselmeer a possible failure of the Afsluitdijk is assumed to have no influence on loads occurring on the IJsselmeer dikes. As failure of the Afsluitdijk is always possible, the consequences of such a failure should be investigated. The objective of this thesis is to...

Floods cause, even in modern countries, a lot of victims and damage every year. Generally, countries invest in prevention and protection, yet, also emergency response measures could be a (last) option. Regarding the latter, a distinction is made between preventive emergency measures (e.g. sand bags to raise the crest level of a flood defence)...

Currently, morphodynamic models as XBeach show substantial overestimations of the erosion rates during breaching and overwash events at barrier islands. The presently used limitations on the Shields parameter and the sediment concentration do hinder erosion, but have undesirable side effects, e.g. the breaching process is suppressed. By...

Lemmens, D.D.M.M. (author)
Sand dikes have a sand core and a clay layer to protect the core against erosion. It is not unlikely that this layer fails due to several failure mechanisms, exposing the sand core to water. This can be catastrophically when water is overtopping the dike. In case the protective cover fails, water can flow over the core and erode the sand,...

Klerk, W.J. (author)
In the Netherlands flood risks are often assessed by using a dike ring approach. This approach has, aside from many advantages, also some disadvantages. The main disadvantage is that, when zooming in on a small area, the effect of the system on that small area and vice versa, is or cannot be accounted for properly. Research has shown that for a...
