Overview:

REF/DIF is a phase-resolving parabolic refraction-diffraction model for ocean surface wave propagation. It was originally developed by Jim Kirby and Tony Dalrymple starting in 1982, based on Kirby's dissertation work.Subsequently, Tuba Ozkan-Haller and Arun Chawla have developed a spectral version of the model called REF/DIF S. Subsequently, Jim Kaihatu and Erick Rogers have served as the lead model testers and debuggers for this code.

Use and initialization of the module:

Although REF/DIF S becomes a subroutine of NearCoM, An input file, indat.dat, is still required by the wave module. The input includes file names for output, subgrid information, physical parameters and wave conditions that can by generated by specgen.f. Water depth is obtained from the master program though a file name for water depth input is still kept in "indat.dat".

Variables provided by the wave module:

The wave module provides 2D (or quasi-3D) circulation modules with wave forcing in two forms: radiation stress and wave force (gradient of radiation stresses). It provides the 3D circulation module with short wave surface stress and body force (see Nearshore POM for detail). In addition, the wave module provides all the wave information that may be needed by the circulation and sediment modules, such as significant wave height, averaged-angle, averaged-wave orbital velocity, wave dissipation rate, and wave mass flux.

Variables required by the wave module:

Water depth (may be updated by the circulation module and the sediment module), depth-averaged current velocity from the circulation module, and wave conditions at open boundaries.
