Effects of wave steepness and relative water depth on wave attenuation by emergent vegetation

摘要

A physical model experiment was conducted to investigate the effects of wave nonlinearity on the attenuation of irregular waves propagating through a stand of uniform, emergent vegetation in constant water depth. The experimental conditions spanned relative water depths from near shallow to near deep water waves (0.45 < kh < 1.49) and wave steepness from linear to nonlinear conditions (0.03 < ak < 0.18). The wave height to water depth ratios were in the range 0.12
