|
Process
| Describe processes represented by the model
|
Flow processes that are driven by the topographic gradient
|
| Describe key physical parameters and equations
|
Elevation, slope and contributing area related quantities
|
| Describe length scale and resolution constraints
|
Applies to any resolution topographic grid, though is most sensible for grids with resolution from 2 to 50 m.
|
| Describe time scale and resolution constraints
|
This is a static model so there is no time scale or resolution
|
| Describe any numerical limitations and issues
|
Presently limited to grids up to 4GB
|
Testing
| Describe available calibration data sets
|
This is not a model with adjustable parameters so calibration is not required. Example datasets are available
|
| Upload calibration data sets if available:
|
|
| Describe available test data sets
|
The Logan River DEM is a small test dataset useful for learning how to use the software
|
| Upload test data sets if available:
|
Media:LoganDemo.zip
|
| Describe ideal data for testing
