Abstract

A depth-averaged non-hydrostatic model is formulated to investigate wave evolution on a water channel with a submerged trapezoidal breakwater. This model is an extension of nonlinear shallow water equations that includes hydrodynamic pressure and vertical velocity. In the momentum equation, a diffus...
