Description: Technical note
BACKGROUND: In the past, most refraction models have dealt only with monochromatic waves. Increasing interest in directional spectra has created a need to quantify the effects of refraction on directional spectra. This program uses Snell's law to refract a specified spectrum over straight, parallel bottom contours to a given depth. The user inputs parameters which describe a spectrum in deep or shallow water. Some simplifying assumptions have been made because of the complexity of the problem. These assumptions impose severe limitations on the application of this model. This model is not meant to replace the more complex numerical models used in most design studies. The more complex models give greater flexibility because fewer assumptions are made, but they require more time and expense to develop model input and are more expensive to run. TWAVE2 should be used as a quick, first estimate of wave conditions.
