Dijkstra, Sam (author)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...master thesis 2023

Teng, Djimin (author)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...master thesis 2023

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

Suzuki, T. (author), Altomare, Corrado (author), Willems, Marc (author), Dan, Sebastian (author)Understanding key flooding processes such as wave overtopping and overflow (i.e., water flows over a structure when the crest level of the structure is lower than the water level in front) is crucial for coastal management and coastal safety assessment. In port and harbour environments, waves are not only perpendicular to the coastal...journal article 2023

Le Grand, Oscar (author)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...master thesis 2022

Nguyên, Hà (author)A sea-dike system is of importance for the protection of the hinterland. However, the effect of very gentle and shallow sloping foreshores (in the order up to 1 in 1000) on wave overtopping processes has not yet been quantified enough and, thus, so far is not well understood. This dissertation seeks an answer to the question of whether the...doctoral thesis 2022

Boon, Casper (author)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...master thesis 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

(author), Kudella, Matthias (author), Akbar, Rizki (author), Altomare, Corrado (author), Suzuki, T. (author)This work presents the results of an investigation on how wave overtopping at a near-vertical seawall at the back of a sandy foreshore is influenced by sequences of erosive storms. The experiments were carried out in the Large Wave Flume (GWK) at Leibniz University, Hannover (Germany). The tested layout consisted of a near-vertical 10/1...journal article 2022

Koosheh, Ali (author), Etemad-Shahidi, Amir (author), Cartwright, Nick (author), Tomlinson, Rodger (author), van Gent, M.R.A. (author)For a safe design of a rubble mound seawall, overtopping characteristics such as the mean overtopping discharge (q) and the maximum individual overtopping volume (V<sub>max</sub>) should be limited. Unlike q, the estimation of V<sub>max</sub> is more complex and requires a wave-by-wave analysis of overtopping as well as a statistical analysis...journal article 2022

Koosheh, Ali (author), Etemad-Shahidi, Amir (author), Cartwright, Nick (author), Tomlinson, Rodger (author), van Gent, M.R.A. (author)Seawalls play a significant role in protecting coastal areas against wave attack and flooding. The accurate estimation of wave overtopping at seawalls is therefore crucial to adequately protect people and infrastructure in these regions. In this study, the mean wave overtopping rate at rubble mound seawalls was investigated through 140 small...journal article 2022

Suzuki, T. (author), García-Feal, Orlando (author), Domínguez, José M. (author), Altomare, Corrado (author)Ongoing climate change is a significant threat to coastal communities. To understand potential risks during extreme storm events, detailed post-overtopping processes are investigated using DualSPHysics and SWASH with a newly developed approach. It is a calibrated-based wave generation: a target incident wave is first obtained from the...journal article 2022

Lashley, Christopher H. (author)Coastal communities across the globe are often protected by structures, such as seawalls, levees or dikes, which allow only a safe volume of water to pass over or “overtop” them due to wave action during storms. The area seaward of these structures is often characterised by shallow, gently sloping beds referred to as foreshores.<br/>As storm...doctoral thesis 2021

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

van Dijk, Peter (author)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...master thesis 2021

van Gent, M.R.A. (author)The amount of wave overtopping at coastal structures such as vertical caisson breakwaters is strongly dependent on the angle of wave attack. The reducing effects of oblique waves on wave overtopping compared to perpendicular wave attack has been studied by means of three-dimensional wave basin tests. In these physical model tests the caisson...journal article 2021

Koosheh, Ali (author), Etemad-Shahidi, Amir (author), Cartwright, Nick (author), Tomlinson, Rodger (author), van Gent, M.R.A. (author)Conventionally, allowable mean overtopping discharge is used as a design criterion for coastal structures. The mean overtopping discharge needs to be limited to ensure structural stability as well as the safety of people, vehicles, and properties behind the structure. Nowadays, limits for the maximum individual overtopping volumes are also...review 2021
