Process
Describe processes represented by the model
|
The two key elements of TUGS model are a surface-based bedload transport equation that allows for calculation of transport rate and grain size distribution of both gravel and sand (Wilcoco and Crowe 2003), and functions that link bedload grain size distributions with surface and subsurface grain size distributions (Hoey and Ferguson 1994; Toro-Escobar et al. 1996; Cui 2007a).
|
Describe key physical parameters and equations
|
See Cui (2007a) for detail: http://dx.doi.org/10.1029/2006WR005330
|
Describe length scale and resolution constraints
|
Length varies, resolution is on the order of several channel width (i.e., 1D model produces only reach-averaged results).
|
Describe time scale and resolution constraints
|
For typical application in a natural river as a prediction tool, the recommended resolution is annual, although it can be as high as hours for simulation of a specific known event.
|
Describe any numerical limitations and issues
|
TUGS was developed with a fairly low budget, and thus, bugs may still exist. There are, however, no known numerical limitations at this point.
|
Testing
Describe available calibration data sets
|
See two papers:

Do you have current or future plans for collaborating with other researchers?
|
Collaboration is always welcomed. The developer, however, does not have any funding to cover such activities. So it may take a fairly long time to finish a modeling exercise if it is done in his spare time.
|
Is there a manual available?
|
No
|
Upload manual if available:
|
|
Model website if any
|
|
Model forum / discussion board
