Abstract

 In this study, a theoretical frequency condition to create the focusing wave packet in uniform current is proposed and validated through wave-current experiments. We observed the maximum surface elevation monotonically increase with the current velocity and the highest elevation of six times higher than the initial wave amplitude is recorded at the highest current velocity in the present experimental conditions. We also found the temporal variations of the spectrum width during the focusing process and the nonlinear steep wave form with double harmonic component at the focusing location.
