The following table lists all required project file card, which must be present in a project file. In addition to these cards, a method of assigning rainfall and overland roughness values must also be selected from the choices below.
| Card | Argument | Description |
|---|---|---|
GSSHAPROJECT |
none | This card must appear first in the project file |
GRIDSIZE ##.## |
real | The size of the square model grid cells (m) (cells will be GRIDSIZExGRIDSIZE. |
ROWS ## |
integer | Number of rows in each raster map. |
COLS ## |
integer | Number of columns in each raster map. |
TOT_TIME ## |
integer | Total duration of the event simulation in minutes. Not required if LONG_TERM is specified. |
TIMESTEP ## |
real | Overall model time step (s). |
OUTSLOPE ##.## |
real | Slope of the cell containing the watershed outlet. Must be positive. Not required if DIFFUSIVE_WAVE is specified. |
OUTROW ## |
integer | The raster row where the catchment outlet is located. Not required if DIFFUSIVE_WAVE is specified. |
OUTCOL ## |
integer | The raster column where the catchment outlet is located. Not required if DIFFUSIVE_WAVE is specified. |
ELEVATION ##.## |
map name | Name of GRASS ASCII map containing watershed elevations (m). |
WATERSHED_MASK "filename.msk" |
map name | Name of GRASS ASCII map containing the watershed shape. Cells marked with 1 lie inside the watershed, while cells marked with a 0 lie outside. Must be the first card after GSSHAPROJECT when using GSSHATM with WMS. |
HYD_FREQ ## |
integer | Time (minutes) that points are written to the output hydrograph file(s). |
SUMMARY "filename.sum" |
file name | Output file summarizing information on options selected, inputs read, simulation results, mass conservation, and warnings generated during the simulation. |
OUTLET_HYDRO "filename.otl" |
file name | Output file containing time series discharge at the catchment outlet. (m3 s-1 default or, ft3 s-1 if QOUT_CFS card specified) |
