Resumen
Experiments were conducted in a wave flume to study the harmonic evolution of a normally incident linear monochromatic wave train as it propagated over a submerged impermeable obstacle of rectangular cross-section. The reflection and transmission characteristics of the system were studied and compared to a linear scattering model, which was found to overpredict the transmission coefficients. The experiment was also simulated using the fully nonlinear model by Grilli et al. (1989), which performed well given its inviscid potential assumptions.
