Project File:Soil Erosion – Optional
From Gsshawiki
Contents
3.10.1 Soil Erosion Simulation - Required
| Card | Argument | Description |
|---|---|---|
SOIL_EROSION ## |
integer | Specifies overland soil erosion calculation method.
|
OUTLET_SED_FLUX "filename.osf" |
file name | Output file name for outlet sediment flux (cms). Output is listed in columns, first being time, followed by sediment flux for each specified sediment size. Wash sediments are listed first. Followed by the sand sizes. |
3.10.2 Soil Erosion Parameters - Required
Soil erosion parameters must be specified in the Mapping Table. See description of inputs in Mapping Table Section - Chapter 12
3.10.3 Optional Inputs
| Card | Argument | Units | Default | Description |
|---|---|---|---|---|
SAND_SIZE ##.## |
real | mm | 0.25 | Representative grain-size for sand-size particles. |
WATER_TEMP ##.## |
real | °C | 20 | Water temperature |
SED_POROSITY ##.## |
real | 0.4 | Value of the porosity of channel bed sediments (0.0-1.0). | |
ADJUST_ELEV "filename.ele" |
file name | Inclusion of card results in new bed elevations being computed every overland soil erosion update | ||
IN_SED_LOC "filename.isl" |
file name | Input file containing a list of internal link/node locations to output sediment hydrographs. Format identical to IN_HYD_LOC option. Valid only with CHAN_EXPLIC or DIFFUSIVE_WAVE. | ||
OUT_SED_LOC "filename.osl" |
file name | Output file containing columns, first of time then sediment discharge (cms) for each sediment size. Sediment sizes that are wash load are listed first, followed by sand sizes. Valid only with CHAN_EXPLIC or DIFFUSIVE_WAVE. | ||
OUTLET_SED_TSS "filename.oss" |
file name | Output file containing columns, first of time then total suspended sediment(mg/L) at the watershed outlet. Valid only with CHAN_EXPLIC or DIFFUSIVE_WAVE. | ||
OUT_TSS_LOC "filename.tss" |
file name | Output file containing columns, first of time then total suspended sediment(mg/L) for each location specified in the IN_SED_LOC file. Valid only with CHAN_EXPLIC or DIFFUSIVE_WAVE. |
3.10.4 Optional Outputs
| Card | Argument | Units | Default | Description | |
|---|---|---|---|---|---|
NET_SED_VOLUME "base_filename.ext" |
file name | mm | none | Output net deposition (+) or erosion (-) | |
VOL_SED_SUSP "base_filename.ext" |
file name | g m-3 | none | Output volume of suspended sediments in each grid cell |
