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...

During the 2011 Great East Japan Tsunami, the world’s deepest breakwaters in Kamaishi and Ofunato, which had been designed to reduce tsunami damage, partially failed after over-topping. The failure was due to a combination of sliding, over-topping induced foundation scour and foundation bearing capacity failure. Hindcasting this failure required...

In the Netherlands flood protection is immensely important for the safety of the nation. The shocking outcome of the 1953 flooding proves this point. In modern days, the development of socioeconomic and climate change factors casts doubt on the effectiveness of conventional approaches to flood risk management. Consequently, this project explored...

Breakwaters are hydraulic structures used to create calm and steady environments for moored ships in harbors. They dampen the wave by dissipating the energy through wave breaking. Most studies of breakwaters have only been carried out on the seaward slope of the structure. However, few have conducted research on the landward-, inner-, slope of...

This report contains a study for the Integral Coastal Defence System for the Malecón in the city of Havana, Cuba. The objective was to develop a sea defence solution that prevents unacceptable flooding of the hinterland and damage of the Malecón seawall. Deriving solutions from earlier reports and using old and new data, a solution is proposed...

PLAXIS study of a primary flood defence in the Netherlands. The influence of water level, precipitation, and wave overtopping on the position of the phreatic surface is being investigated. The hydraulic loads are applied to a clay dike with a cracked top layer and a sand dike with a cracked clay cover. The findings are related to the current...

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...

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...

Nowadays, the use of concrete armour units on rubble mound breakwaters designs has become a common practice. Concrete armour units can be placed in a single layer system or in a double layer system and can its placement can be either random or uniform. Recently, Delta Marine Consultants have designed a new armour unit called Xbloc+. This new...

The Houston Metropolitan area is a hurricane prone area and vulnerable to flooding by large storm surges caused by these extreme storm events. The area is a major economic center in the State of Texas and even the whole United States. Protection of the area against flooding is extremely necessary to protect the economy, community and environment...

Various flood protection measures are studied across the globe, and nature-friendly and environmentally resilient methods are gaining more attention. As part of the building with nature initiative, the project BE SAFE (Bio-Engineering for SAFEty) studies the effects of a vegetated foreshore as a flood protection measure which is found to be very...

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...

Breakwaters with single layer concrete armour are very commonly applied nowadays. Much research is available on the stability of single layer armour units on the seaward slope. However, rear slopes design methods for single layer armour units are rare. On rear side slopes usually similar sized units as on the seaward slope are applied. Limited...

Large parts of the Netherlands are exposed to the threats of flooding due to the influence of high water coming from the North Sea region, due to high discharge of rivers like the Meuse and Rhine or due to a combination of North Sea water levels and river discharges. In order to cope these threats, strategies are developed in the Delta Program...

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...

Marine contractors deal with processes that are understood qualitatively but are hard to quantify. The amount of data available for these processes is ever growing, and so too the intrinsic value that lies within this data. Several data driven model approaches can be used to analyse this process data, one being a Bayesian Network (BN) approach....

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...
