Overtopping of Coastal Structures by Tsunami Waves [PDF]
Geosciences, 2017 Following the 2011 Tohoku Earthquake and Tsunami, Japanese tsunami protection guidelines stipulate that coastal defences should ensure that settlements are shielded from the coastal inundation that would result from Level 1 tsunami events (with return periods in the order of about 100 years).

Numerical modelling of wave overtopping at dikes using OpenFOAM®
Coastal Engineering, 2021 Accurate calculation of wave overtopping is important for determining the required crest height and geometry of a dike. Berms and roughness elements are widely used to reduce the average overtopping discharge at dikes while the reductive effects of berm ...

A Critical Analysis and Validation of the Accuracy of Wave Overtopping Prediction Formulae for OWECs
Energies, 2018 The development of wave energy devices is growing in recent years. One type of device is the overtopping wave energy converter (OWEC), for which the knowledge of the wave overtopping rates is a basic and crucial aspect in their design. In particular, the

Instability of Grass Caused by Wave Overtopping [PDF]
Scour and Erosion, 2010 This paper presents a method to deal with the instability of turf in a grass cover that could be considered as an engineering approach, in which both turbulence and two strength models (root model and turf-element model) are discussed in a heuristic way. Turbulence is discussed because of its essential role in erosion.

Influence of directional spreading on wave overtopping of sea dikes with gentle and shallow foreshores [PDF]
, 2020 The work highlights the importance of directional spreading effects on wave overtopping estimation in shallow and mild sloping foreshores. Wave short-crestedness leads, in general, to a reduction of mean overtopping discharges on coastal structures.

Characterization of Overtopping Waves on Sea Dikes with Gentle and Shallow Foreshores
Journal of Marine Science and Engineering, 2020 Due to ongoing climate change, overtopping risk is increasing. In order to have effective countermeasures, it is useful to understand overtopping processes in details.

Numerical Analysis of Wind Effect on Wave Overtopping on a Vertical Seawall
Water, 2022 Onshore wind significantly affects wave run-up and overtopping, thereby representing a major variable to account for in the design process. The aim of this study is to analyze the ability of numerical models to properly reproduce the wind effect on the ...
