Programming language	Fortran77
Other program language
Code optimized	Single Processor
Multiple processors implemented
Nr of distributed processors
Nr of shared processors
Start year development	1982
Does model development still take place?	Yes
If above answer is no, provide end year model development
Code development status
When did you indicate the 'code development status'?
Model availability	As code
Source code availability (Or provide future intension)	Through web repository
Source web address	http://chinacat.coastal.udel.edu/programs/refdif/refdif.html

Program license type	Other
Program license type other	GNU General Public License, Version 2
Memory requirements	--
Typical run time	--

Describe input parameters	The input includes file names for output, subgrid information, physical parameters and wave conditions. Water depth is obtained from the master program though a file name for water depth input is still kept in "indat.dat".
Input format	Binary
Other input format
Describe output parameters	Model output: Complex amplitude, Wave Heights and angles Radiation stresses and forcing terms Wave induced mass flux Velocity moments for bottom stress calculation
Output format	Binary
Other output format
Pre-processing software needed?	Yes
Describe pre-processing software	In cases where the standard required the use of a non-typical format (as in the use of the machine-independent binary HDF formats for large arrays), then the data transfer to and from LRSS is handled using a pre- and post-processing layer.
Post-processing software needed?	Yes
Describe post-processing software	In cases where the standard required the use of a non-typical format (as in the use of the machine-independent binary HDF formats for large arrays), then the data transfer to and from LRSS is handled using a pre- and post-processing layer.
Visualization software needed?	No
If above answer is yes
Other visualization software

Describe processes represented by the model	See manual version3
Describe key physical parameters and equations	See manual version3
Describe length scale and resolution constraints	Assumptions: The REF/DIF 1 model, in parabolic form, has a number of assumptions inherent in it and it is necessary to discuss these directly. These assumptions are: Mild bottom slope. Weak nonlinearity. The wave direction is conﬁned to a sector ±70 ◦ to the principal assumed wave direction, due to the use of the minimax wide angle parabolic approximation of Kirby (1986b).
Describe time scale and resolution constraints	--
Describe any numerical limitations and issues	--

Describe available calibration data sets	--
Upload calibration data sets if available:
Describe available test data sets	--
Upload test data sets if available:
Describe ideal data for testing	--

Do you have current or future plans for collaborating with other researchers?	--

Is there a manual available?	Yes
Upload manual if available:	Media:REF-DIF users manual 1993.pdf, Media:Refdif1v30-2002.pdf
Model website if any	http://chinacat.coastal.udel.edu/programs/refdif/refdif.html
Model forum / discussion board	--

Comments	Both codes are undergoing extensive revisions needed to incorporate them into the framework of the NearCoM Nearshore Community Model.

This part will be filled out by CSDMS staff

OpenMI compliant	No not possible

 |Extended model description=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. This work led to the development of REF/DIF 1, a monochromatic wave model.
