Input File Description
STWAVE has four input files. These files specify model parameters,
bathymetry, incident wave spectra, and current fields. The current field file is
optional and required only if the wave-current interaction is specified. The other
three files are required. The input files are most easily generated using the SMS
interface discussed in Chapter 5, but may also be generated using an editor or
other programs. File formats for the input files must remain the same, regardless
of how the files are generated. Parameter names starting with "N," "I," or "J"
indicate integer parameter values are required. All other names indicate real
parameter values. A schematic of the STWAVE input and output files is given in
Figure 4.
