Boussinesq Modeling for Inlets, Harbors, and Structures (Bouss-2D)

Abstract

Abstract : The Boussinesq Modeling Technology (BMT) comprises of one- and two- dimensional (BOUSS-2D) numerical wave models for simulating nearshore waves and wave-induced circulation. This technology is applicable to a variety of high-fidelity coastal and ocean engineering and naval architecture problems, including transformation of waves over small to medium spatial scale regions (1-15 km); planning and design of ports/harbors/ marinas; investigation of wave agitation and harbor resonance; risk analysis for ship transit; ship mooring & motion studies; wave breaking over submerged obstacles; wave-structure interaction; wave runup and overtopping of coastal structures, levees, groins, beaches, dunes and barrier islands; breaking-induced nearshore circulation in surf and swash zone; wave-current interaction in channels and inlets; generation and impacts of infra-gravity waves on ports and harbors; wave transformation over reefs, shoals/berms and around artificial islands; and impacts of vessel-generated waves on erosion of coastal shorelines and river banks. BMT is a Federal Emergency Management Agency (FEMA) approved model for flooding and inundation works for use in military and civil work applications. It may be used from deep to shallow water to simulate the nonlinear wave processes of interest in the open coast, nearshore zone, and inside complicated port/harbor basins. Wave processes represented by BOUSS-2D include wave reflection and diffraction near structures, energy dissipation due to wave breaking and bottom friction, crossspectral energy transfer due to nonlinear wave-wave interactions, breaking-induced longshore and rip currents, wave-current and wave interaction with porous media, wave propagation over vegetated areas, wetlands and marshes, and vessel wakes and ship-channel-shore-bank interactions.
