ModeErod |
Mode for sediment transport model |
The erosion model to use
- 0 = default model. (Spatially uniform erodibility).
- 1=Erosion depth dependent erodibility (input in erosion model file)
- 2=Spatially random erodibility using spatial
state in the RST2 file.
- 3=Regions of spatially varied fluvial erosion model (input in erosion
model file)

InputFile: Sediment Transport Model |
Erosion Model File
- A supplementary file from which erosion data is read in the more advanced
sediment transport models.

The Default Sediment Transport Model:

|
Fluvial Sediment Transport Model Component:

|
39 |
b1 |
Coefficient on the fluvial transport relationship |
|
40 |
m1 |
Exponent on the discharge in the fluvial transport
relationship |
- The exponent on discharge in the fluvial sediment transport equation
|
41 |
n1 |
Exponent on the slope in the fluvial transport relationship |
- The exponent on slope in the fluvial sediment transport equation
|
24 |
QSTHold |
Fluvial transport threshold |
- A threshold below which fluvial sediment transport does not occur
|
59 |
b12 |
Coefficient on the second fluvial fluvial transport
equation |
- (RESEARCH ONLY)
- The erodibility of a second fluvial sediment process. This process
occurs in the channel ... the first process (i.e. b1) occurs on the hillslope.
|
60 |
m12 |
Exponent on discharge for the second fluvial transport
equation |
- (RESEARCH ONLY)
- The exponent on discharge in a second fluvial sediment transport process.
This process occurs in the channel ... the first process (i.e. m1) occurs
on the hillslope.
|
53 |
Ot |
The ratio of overland: channel fluvial transport rate |
- The ratio of the erodability on the hillslope compared to that
in the channel. A value of less than 1 indicates that hillslopes have a
lower erodibility than channels
|
42 |
BulkDen |
Bulk density of the soil |
- This is the bulk density of the eroded sediment. This is used to convert
between tonnes of sediment eroded and the equivalent cubic metres of sediment.
- If the sediment transport rate is expressed in cubic metres of sediment
per time step then this correction is unnecessary and Bulk=1
|
50 |
Cover |
Vegetation cover factor |
- A cover factor that can allow for vegetation effects or agricultural
practice (ala the correction factors in the USLE, etc)
|
Diffusive Sediment Transport Model Component:

|
21 |
Dz |
Diffusivity of diffusive transport |
- Diffusivity of diffusive transport
|
22 |
Dzn |
Nonlinearity of diffusive transport |
- Nonlinearity of diffusive transport
|
23 |
dZTHold |
Diffusive transport threshold |
- Diffusive transport threshold below which diffusive transport
does not occur
|
Not Included in EAMS interface:
(Available only through running SIBERIA directly)
The diffusive transport is modified from above as follows

|
51 |
s0max |

- Slope stability threshold for diffusive transport
