... Consequently such methods are computationally very expensive, and therefore less popular in the context of modelling MSD-generated waves. For example, in the last few decades, few studies of landslide-generated waves have employed a Lagrangian approach [see15, [19][20][21][22] [23] is the use of a semi-implicit numerical scheme for pressure, based on empirical coefficients that require further tuning. In the present paper, we improve the model of Ref. Renzi and Dias [23] by using an explicit algorithm to solve the pressure field. ...

... Later this model was extended to three dimensions by Deborah and Peregrine (1998), and the case of trapped air was studied by Wood et al. (2000). Subsequently, this approach has been applied in more complicated configurations, including the breaking wave impact on a wall (Lobovský et al. 2014;Lugni et al. 2006), breaking wave impact on a permeable breakwater (Cooker 2013), wave impact on an oscillating wave energy converter (Renzi et al. 2018); and wave impact on a hydraulic structure with an overhang (Chen et al. 2019). Chen et al. (2019) also used impact impulses as the primary design variable to estimate the impulsive reaction force. ...

... Since the filling flow has been studied mostly from an analytical 16,17 and physical 18,19 point of view, the aim of the present research is to analyze the filling flow through laboratory and numerical experiments, in order to validate the model by 1 and to provide a relationship between the incoming wave properties and the filling flow hydraulic parameters. A Plexiglas box was used to resemble the cavity, installed at one side of a rectangular tank and the incoming flow was generated by means of the sloshing flow in a tank horizontally forced by a mechanical system. ...

... The maximum offshore wave height H max can be approximated by 2H s (e.g., Krogstad, 1985;Cattrell et al., 2018), but seas evolve as they transit the shelf and shoal toward land, so that H max obtained from buoy data may not match maximum wave height at the coast. Wave energy attenuates across the continental shelf, typically causing large swell height to decrease by about half (Ardhuin et al., 2003;Janjić et al., 2018), but amplification commonly occurs near shore, as shoaling waves interact with sea bed and coast (Viotti and Dias, 2014;Akrish et al., 2016;Brennan et al., 2017). Predicting coastal wave heights is therefore complicated. ...

... A better understanding of the pressure fields produced by intense surface waves is necessary for more efficient diagnostics of sea conditions, as well as for the improvement of the methods to solve the inverse problem. Approximate analytic solutions for particular surface wave patterns (e.g., long-wave solitons in shallow water; weakly nonlinear cross seas; wave groups in relatively deep water, etc, see Pellet et al, 2017;Slunyaev et al, 2018;Touboul & Pelinovsky, 2018) are useful for better qualitative understanding, and may be used as benchmarks. ...

... The most restrictive assumption is The analytical 3D model developed by Renzi and Dias [16] is used to compute the load on the flap. This is the same model that is implemented to determine the hydrodynamic loading on an array of OWSCs in random seas [21][22][23]. Until now, this model had only been used to compute forces under normal operational conditions for OWSCs, that is waves with periods between 5 s and 20 s. Even though there is no assumption on the wave period in the derivation of the model, special care must be taken when evaluating the solution for long waves. ...

... They showed that a simple, nearly monochromatic wave group can produce a run-up amplitude in excess of six times the far-field amplitude. Viotti et al. [5] extended the model to account for non-flat bathymetry, while Brennan et al. [6] examined the associated pressure fluctuations on the barrier. Akrish et al. [7,8] reproduced the run-up using a higher order spectral (HOS) method, and also looked at the resulting force on the wall. ...

... Over the past two decades, a number of studies are conducted to understand how OSWECs' structures and interactions between ocean waves and flaps affect converters performance. Henry et al.'s experiment on oscillating surge wave energy converters is considered as one of the most influential pieces of research [25], which demonstrated how the performance of oscillating surge wave energy converters (OSWECs) is affected by seven different factors, including wave period, wave power, flap's relative density, water depth, free-board of the flap, the gap between the tubes, gap underneath the flap, and flap width. These parameters were assessed in their two models in order to estimate the absorbed energy from incoming waves [26,27]. ...

... However, opposite conclusions have been drawn by other researchers. Tiron et al. [9] quantified marine growth on WECs using numerical population-dynamic models. Given that the pre-dicted biofouling accounted for approximately 10% of the total mass of the WEC, they concluded that biofouling could have an important effect on its energy-absorption capabilities. ...
