To provide coastal engineers and scientists with a detailed inter-comparison of widely used parametric wave transformation models, several models are tested and calibrated with extensive observations from six field experiments on barred and unbarred beaches. Using previously calibrated (default) values of a free parameter T, all models predict the observations reasonably well (median root-mean-square wave height errors are between 10% and 20%) at all field sites. Model errors can be reduced by roughly 50% by tuning T for each data record. No tuned or default model provides the best predictions for all data records or at all experiments. Tuned T differ for the different models and experiments, but in all cases T increases as the hyperbolic tangent of the deep-water wave height, H.. Data from two experiments are used to estimate empirical, universal curves for T based on Ho. Using the new parameterization, all models have similar accuracy, and usually show increased skill relative to using default T. (c) 2007 Elsevier B.V. All rights reserved.
