“…For the boundary condition of impermeable cylinder in a quadrilateral mesh system according to spatial discretization based on FDM, the impermeable condition is adopted in the normal direction and slip condition is adopted in the tangential force for the polygon structure for the cylinder by applying the reasonable boundary [38,39] based on Petit et al [40].…”

“…The mechanism and hydrodynamic characteristics of the interactions between waves and currents were analyzed accounting for the densities of freshwater and seawater. For this purpose, a 3-D numerical analysis model [47,48] based on the existing 3-D numerical wave tank (NWT), LES-WASS-3D [49][50][51] was introduced to analyze density currents in this study.…”

“…In addition, to analyze sub-grid scale (SGS) turbulence, Smagorinsky turbulence model (STM [54]) for the large eddy simulation (LES) was adopted in the NWT [55]. By considering inertia [56], turbulence [57,58], and laminar flow resistance [58,59] according to porous medium characteristics (diameter, porosity, and shape), the model can directly analyze interactions among waves, structures, and the seabed [49][50][51].…”

“…In addition, hybrid methods that combine rigid and flexible methods, such as beach nourishment, eco-friendly artificial vegetation, sand collectors, and beach drainage methods, have become the preferred approach, and studies on preventing coastal erosion using flexible methods have been actively conducted [9][10][11][12]. For instance, Hur et al [13] performed an experiment to control the flow at an open inlet by developing a submerged breakwater with a drainage channel to reduce the water-level rise behind the structure. Oh et al [14] analyzed the hydraulic stability through a hydraulic experiment using a geotextile tube to perform monitoring and verification.…”
