Mata, Marisol Irías (author), van Gent, M.R.A. (author)Numerical modelling of wave interaction with rock-armoured rubble mound breakwaters has been performed to study wave overtopping. The influences of the slope angle, a berm in the seaward slope, a protruding crest wall, a recurved parapet, and the wave steepness have been studied using a validated CFD model (OpenFOAM). The numerical modelling...journal article 2023

van der Bijl, Ruben (author)Climate change affects sea level rise and the safety of the people living behind seadikes. In order to prepare for this, several adaptation measures are available to reduce the overtopping discharge. Wave overtopping can be reduced by including roughness elements or adding a berm. Another possibility is to employ crest elements such as a...master thesis 2022

Dirkx, Nic (author), Bosselaar, Marcel (author), Oomen, T.A.E. (author)Handling peak amplitude constraints, or equivalently l∞-norm constraints, is an important application demand in experiment design for system identification. The aim of this letter is to present a method for the design of excitation signals with prescribed power spectrum under l∞-norm constraints for systems with many inputs and outputs. The...journal article 2022

Wave overtopping discharges at rubble mound breakwaters including effects of a crest wall and a bermvan Gent, M.R.A. (author), Wolters, Guido (author), Capel, Alex (author)Physical model tests have been performed to study wave overtopping at rubble mound breakwaters, including breakwaters with a crest wall, breakwaters with a berm, and breakwaters with a crest wall and a berm. For rubble mound structures with a protruding crest wall or with a stable berm, limited information is available in literature even...journal article 2022

Hogeveen, Kevin (author)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...master thesis 2021

Vasarmidis, Panagiotis (author), Stratigaki, Vasiliki (author), Suzuki, T. (author), Zijlema, M. (author), Troch, Peter (author)The weakly reflective wave generation is a wave generation and absorption method in phase-resolving models, based on the assumption that the waves propagating towards the wave generation boundary are small amplitude shallow water waves with direction perpendicular to the boundary. This assumption makes the method weakly reflective for...journal article 2021

Jonker, R.G. (author)In this research OpenFOAM is used to model and determine the complex hydrodynamic behaviour of a Homogeneous low-crested structure (HLCS) consisting of cubipod artificial concrete elements. The validated model is used to gain insight in the design sensitivities of a two dimensional cross sectional layout to reduce sea wall overtopping. HLCS and...master thesis 2020

Ruwiel, Tim (author)XblocPlus is a single layer armour unit that is recently developed by BAM Infraconsult. It is the successor of the Xbloc. An important advantage of the XblocPlus is the relatively high construction speed compared to the Xbloc. The increased construction speed is caused by the possibility to place XblocPlus in a uniform pattern and the relatively...master thesis 2020

Grigoris, Xenofon (author)The Xbloc<sup>Plus</sup> (referred to as Xbloc+) is a new, uniformly placed single layer armour unit, developed by Delta Marine Consultants (BAM Infraconsult). Although a breakwater armour layer with Xbloc<sup>Plus</sup> combines material saving and easy placement with increased stability, the transition between the armour layer and the crest is...master thesis 2019

Streicher, Maximilian (author), Kortenhaus, Andreas (author), Marinov, Krasimir (author), Hirt, Matthias (author), Hughes, Steven (author), Hofland, B. (author), Scheres, Babette (author), Schüttrumpf, Holger (author)Short duration bores in the coastal zone are generated by wave breaking in shallow water and mild foreshore conditions. In storm weather situations and for sea level rise scenarios, these bores approach the dike and interact with previously overtopped or reflected bores. Combined laser scanner and video measurements were used to study the...journal article 2019

Janssen, Danny (author)In the past humans used to protect their shores mainly with rocks. In the past decades the shore protections did gently shift to concrete element protections. An example of an often applied concrete armour unit is the Xbloc. This element is quite strong and well investigated. BAM Infraconsult has developed a uniformly placed armor unit, the...master thesis 2018

Rietmeijer, Anton (author)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...master thesis 2017

Lioutas, A. (author), Smith, G.M. (author), Verhagen, H.J. (author)The scope of this research is to find an empirical formula to describe the distribution of wave overtopping in the region behind the crest. A physical model was set up in which irregular waves were generated. In order to find a formula which adequately describes the test observations, the influence of several parameters has been analysed. The...conference paper 2012

(author)Wide crested dike can reduce the kinetic energy of the overtopping wave and make the overtopping wave to flow back to the seaside. If a coastal town were built on or near a dike, the overtopping wave running on the dike crest generates the force which can affect the buildings located in its path. However, quantifying the hydrodynamic load on the...conference paper 2012

Van Kester, D.C.P. (author)The goal of this master thesis is to describe the spatial distribution of the wave overtopping discharge over and behind the crest of a coastal defence structure. The influence of the most relevant parameters on this process is explored. This research has been performed by means of a physical model. The following relevant parameters were varied...master thesis 2009

Van Steeg, P. (author)In the framework of the ComCoast project, the concept of the Crest Drainage Dike has been studied regarding the reduction of wave overtopping. This study only focuses on the average wave overtopping discharge. The basic concept of the Crest Drainage Dike is a basin, integrated in the crest of the dike, that collects overtopping water and thus...master thesis 2007
