| description | This paper presents a novel numerical method for non-linear water wave interaction with a vertical structure of arbitrary horizontal shape. The wave motion is described by a set of non-linear Boussinesq-type equations. These are solved numerically using a Godunov-type finite volume method on Cartesian grids with cut cells. The higher-order dispersive Boussinesq terms are approximated by finite differences. The main advantage of this approach is that not only is the proposed scheme conservative, but also no special algorithm is required to simulate discontinuous flows such as hydraulic jumps and broken waves. Regular waves incident on a bottom-mounted cylinder are simulated and the predicted surface elevation on the body compares well to laboratory measurements.
