Abstract
The objective of this study is to propose the most suitable dissipation model for computing the transformation of spectral significant wave height (Hm0). A wide range of experimental conditions, covering small-scale, large-scale, and field experiments, were used to examine the models. Fourteen existing dissipation models, for computing root-mean-square wave heights (H rms), were applied to compute Hm0. The coefficients of the models were re-calibrated and the accuracy of the models was compared. It appears that the model of Janssen and Battjes [2007] with new coefficients gives the best overall prediction. The simple model proposed in the present paper was modified by changing the formula of stable wave height in the dissipation model. Comparing with the existing models, the modified model is the simplest one but gives better accuracy than those of existing models.
