Abstract
This paper continues the work reported in Part I, on a shallow-water device in nondispersive, nonlinear waves. The first objective here is to study a method to control the motion of a bottom-supported, oscillating water column device, for increased energy absorption at a chosen damping level. Also studied in this paper is the effect of nonlinear viscous damping. The efficiencies here are lower than observed for the linear damping case, and the optimum damping is found to vary slightly with incident wave amplitude.
