An evaluation of directional analysis techniques for multidirectional, partially reflected waves .2. application to field data

Based on the findings of a numerical investigation, presented in the part 1 companion paper, two methods of directional analysis, the maximum likeliho od method (MLM) and the Bayesian directional method (BDM) are applied to ov er 80 field data sets. These cover a wide range of environmental conditions , for which multidirectional, partially reflective sea states exist. The re sults show that trends similar to those found using the numerical simulatio ns are observed in the field estimates of relative predictions of incident significant wave height, average reflection coefficients, main directions a nd directional spreading. It is concluded that overall the BDM produces the more accurate results when applied to real sea waves.
