In/Output

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


Process

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:

  1. Mild bottom slope.
  2. Weak nonlinearity.
  3. 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).
