Preliminary Design Tools for Hydrodynamic Aspects of Submerged Impermeable Breakwaters

The boundary element method (BEM) with Lagrangian formulation is a conceptually simple and efficient for the simulation of nonlinear wave shoaling, or without impermeable coastal structures, up to breaking. However, in post-breaking flows, domain no longer simply connected, BEM not generation new free surface. Volumes fluid (VOF) methods are made track fluid-free surfaces after breaking, but they more numerically complex less relative before This study presents numerical model, named BELWF—boundary elements flume—for mathematical two-dimensional flumes. BELWF can simulate hydrodynamics shoaling over coast profile, submerged structures any geometry. developed model applied Geotube structures. validated by comparisons OpenFOAM simulations. Both simulations show that most critical state, regarding sliding stability Geotube, occurs, typically just where reasonably assesses loads stability. Hence, valid preliminary design Finally, practical example complete process along sloped shore structure at shallow water, which develops plunging breaker. well captures event considering structure.
