Evolution of waves and currents over a submerged laboratory shoal

A New 3d Roller Approach for Facing Rotational Surf Zone Hydrodynamics

“…the ratio of the local depth over the incident wave height. Figure 7 shows the top view of such an outcome, for the non breaking M2 case, obtained by using the proposed model and the results obtained by Choi et. al (2009) by using the FUNWAVE model (Chen et al, 2000).…”

“…Moreover other authors have also adopted such a test as a benchmark for validating numerical models. As an example, Choi et al (2009) performed numerical simulations using both phase-averaged literature models and phase-resolving literature models. In particular they used also the Boussinesq-type of model developed by Chen et al (2000), known in the coastal community as FUNWAVE.…”

Marine Renewable Energy

“…Designed to simulate the propagation of waves in shallow nearshore areas (depth <½ wavelength), SWAN is often applied for wave resource assessments (Ruehl 2013;Dykes et al 2002;Rusu and Soares 2009;Choi et al 2009;Robertson et al 2014). SWAN is an open-source wave model that was developed at the Delft University of Technology and was built as an extension of the 3G WAM model.…”

“…Such patterns also occur when a wave field interacts with isolated bathymetric features (for example, see Choi et al 2009), and their prediction requires the consideration of wave-phase information. A shadow region forms behind the devices but the diffraction process, acting over long distances shoreward, reduces the wave shadow by transmitting energy into the lee of the array.…”

Numerical simulation of wave-induced currents combined with parabolic mild-slope equation in curvilinear coordinates

“…The research work is characterized by a common need for a separate wave module calculating radiation stresses to the flow module. For instance, the Nearshore Circulation model (SHORECIRC), developed by the University of Delaware, requires a wave model to offer the driving force (Svendsen et al, 2002); , Yoon et al (2004), Shen et al (2006), Tang et al (2006Tang et al ( , 2008aTang et al ( , 2008b and Tong et al (2011), respectively, combined different types of mild-slope equation with the shallow water equations to simulate nearshore wave-induced currents; the Simulating Waves Nearshore model (SWAN) was coupled with the SHORECIRC by Choi et al (2007) to calculate the flow field caused by breaking waves; Choi et al (2009) also compared several different wave drivers and concluded that not only the impact of waves on currents but also the impact of wave-current interaction should be considered when nearshore circulation is studied.…”
