A Practical Post-Processing Method to Obtain Wave Parameters from Phase-Resolving Wave Model Results

Abstract

This paper describes a new method to obtain directional and amplitude information from the results of phase-resolving computational wave models. The output of this type of models is the wave field resulting from incoming and reflected wave components combined, whereas specific information on separate wave components (directions, heights, periods) is generally required for design purposes. The new post-processing method that we present to obtain this information has been validated using analytically prescribed wave signals as well as results from a mild-slope model, which is the phase-resolving wave model that has been considered so far. The versatility and usefulness of the method is illustrated in a number of application examples for ports. The results show that the new method is practical and produces reliable results.
