AbstractThe evolution of long-crested surface waves subject to sideband perturbations is investigated with two different numerical models: a direct solver for the Euler equations using a nonorthogonal boundary-fitted curvilinear coordinate system and an FFT-accelerated boundary integral method. The numerical solutions are then validated with laboratory experiments performed in the NRC-IOT Ocean Engineering Basin with a segmented wave-maker operating in piston mode. The numerical models are forced by a point measurement of the free surface elevation at a wave probe close to the wave-maker and the numerical solutions are compared with the measured timeseries of the surface elevation at a few wave probe locations downstream.
