Wave trapping by dual porous barriers near a wall in the presence of bottom undulation

Using a porous-media approach for CFD modelling of wave interaction with thin perforated structures

“…Regarding the porosity representation, most potentialflow models apply the porous pressure-drop in a linearised way and only few models use a non-linear formulation. Examples for work that use a linear relationship between pressure-drop and flow velocity are studies on a nearly vertical porous wall, done by Chakrabarti and Sahoo (1996), or for investigations on the effects of bottom topography, done by Kaligatla and Sahoo (2017) and Kaligatla et al (2018). A quadratic pressure-drop formulation has for instance been used by Mei et al (1974) in combination with shallow water theory, by Bennett et al (1992) for thin vertical barriers and by Liu and Li (2017) for an iterative boundary element model.…”

Wave scattering by a vertical cylinder with a submerged porous plate: Further analysis

“…Many investigations have been carried out to investigate the effect of porous structures on wave loads acting on coastal and offshore structures. Kaligatla et al (2017) found that the existence of the porous wall is beneficial for mitigation of the wave loads on the seawall. Koley and Sahoo (2021) investigated water wave interaction with an array of vertical flexible porous barriers.…”

Wave–current-surge interaction in a changing climate over a shallow continental shelf region

“…In a global perspective, there are various mathematical studies (Mandal et al, 2013;Das et al, 2016aDas et al, , 2018Kaligatla et al, 2017;Behera et al, 2018;Kar et al, 2019Kar et al, , 2020, numerical (Ris et al, 1999;Millar et al, 2007;Gorrell et al, 2011;Vlasenko and Stashchuk, 2007;Dietrich et al, 2013;Cunha, 2015;Williams et al, 2015). On the other hand, experimental studies (Bondzie and Panchang, 1993;Plant et al, 2009;Morelissen et al, 2003) addressed both regional and global wave-current-surge characteristics over complex bathymetry.…”
