摘要

This paper introduces a video-based method for directional wave measurement in the physical model setting. The motivation for this study is to provide a non-intrusive method for highly resolved and accurate measurement of wave diffraction in the vicinity of coastal inlet structures. Video observations of wave direction in the diffraction region behind a breakwater structure for three spectra generated by an offshore wave paddle are compared to ADV observations. Initial video-ADV comparisons result in a vector-mean wave direction measurement accuracy within 5 degrees. Experimental results provide a suitable benchmark data set for validation of wave transformation models that incorporate wave diffraction.
