The objective of this research is to gather more information about a possible relation between the slope angle of a rubble mound breakwater and the wave overtopping at this breakwater. The following research question is covered in this thesis: What is the influence of the slope angle of rubble mound breakwaters on wave overtopping? To answer...

For the past 2000 years river training works have been performed on the Dutch rivers. These training works have shaped the river system of today. Another result of the river training works, especially over the last two centuries, is a decrease in biodiversity. To protect the biodiversity some floodplains in the Netherlands have been classified...

Due to the rising sea level in combination with land subsidence there is a need to reinforce the dikes. The use of a crest element to increase the height of the dike is an effective and relatively cheap way to reinforce the dikes (Hogeveen, 2021). When a crest element is used, the jet generated by wave breaking on the dike slope impacts on the...

If sea level rises faster than anticipated in the initial design of rubble mound breakwaters, a serious threat is posed to their functionality. To limit wave overtopping, breakwaters must be adapted to the rising sea level and subsequent increase in wave loading due to reduced depth-induced wave breaking. However, the...

Sea level rise will increase the risk of flooding in coastal areas. This poses a risk to the coastal protection as well as rivers and lakes close to the coast. Solutions are needed to cope with this threat. The past decade, nature based solutions have gained significant interest. One of these solutions could be sandy foreshores. Due to the use...

Wave overtopping, in which a wave washes over the crest of a dike and damages its inner slope, is one of the many mechanisms that is found to be responsible for dike failures. As these dikes are generally covered with grass, insight into the erosion resistance of these grass covers against wave overtopping is desired. To assess the performance...

Rubble mound structures are often constructed to prevent severe wave damage to ships. By constructing the crest at a certain level, the waves are reduced such that safety is ensured. However, a large increase in sea level rise is expected in the next century due to climate change. Because of this, multiple adaptations might be necessary to meet...

Large areas of the world are protected by flood defence systems. A common part of flood defence systems is a levee with grass cover, with the primary function to protect hinterland against floods. Waveovertopping might lead to erosion of the grass cover, followed by erosion of the inner slope and potentially levee breaching. The wave overtopping...

Worldwide, rubble mound breakwaters are designed and built to shelter and protect coastal areas from overtopping and flooding, especially harbours and shorelines. Rubble mound breakwaters are essential to preserve desired hydraulic conditions within the hinterland, avoiding damage to inhabited or industrial areas. This research focuses on the...

Wegman, Rik (author)
Wave overtopping is responsible for many dike failures, dike breaches and severe flooding. The erosion resistance of dikes to overtopping waves is determined by the strength of the grass cover. Therefore, a thorough understanding of the erosion resistance of grass covers is desired to enable a good and effective dike management. In the existing...

van Melis, Tijmen (author)
Wave overtopping is an important aspect for the design of rubble mound breakwaters. Acceptable overtopping limits are usually based on the mean overtopping discharge or the maximum overtopping volume (EurOtop, 2018). For temporary situations, such as breakwaters under construction, overtopping limits are not clearly defined. This complicates the...

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...

Contrary to a breakwater outer slope, rear-slope revetment does not have to withstand breaking waves. However, generally, an equal dimensioned revetment is used on both the inner- and outer slope. Although with low-crested breakwaters severe overtopping occurs, the application of similarly sized armour on both sides still results in an over...

Wave overtopping in harbour areas is a fairly untreated topic in the context of flood risk analyses. Pragmatic approaches were undertaken to evaluate the possible influence of wave overtopping on the frequency of flooding. However no consensus was reached on how wave overtopping in a harbour area could be quantified. Therefore it is also...

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...

Oosterlo, P. (author)
In this thesis, a method was developed, with which the infragravity waves and morphological changes of a sandy foreshore are included in the calculation of the probability of dike failure due to wave overtopping. Constructing a natural foreshore in front of the dike can be an attractive and innovative method to decrease the failure probability....

This report presents a study of the Malecón Tradicional in front of ‘Centro de Havana’ and ‘Havana Vieja’ in the city Havana, Cuba. The objective is to develop a sea defence solution that prevents unacceptable flooding of the hinterland and damage of the Malecón seawall. Implementing the recommended solutions reduces the overtopping sufficiently...

There is a shift in the approach for designing coastal structures. In the past, dikes were designed on the probability of exceedance of an incoming wave during storm conditions. In the near future, the design criteria will be the probability of flooding of the hinterland. In order to determine this flooding probability, the strength of the dike...

The main goal of this project is to verify the numerical model SWASH when dealing with overtopping prediction by comparison of full scale measurement results to results of numerical model testing. For that purpose, the harbour in Zeebrugge (Belgium) has been considered; there, several storm events have been measured in a rubble mound breakwater...

Numerieke modellen worden alsmaar belangrijker om voorspellingen te doen in de waterbouwkunde. Het is namelijk veel eenvoudiger en goedkoper om proeven numeriek te simuleren dan om deze uit te voeren in een laboratoriumopstelling. De numerieke modellen moeten echter wel worden gevalideerd aan de hand van metingen. In dit rapport wordt de...
