Program license type	Other
Program license type other	Propritary code
Memory requirements	Depending on node,number of sizes and number of layers information has to be stored
Typical run time	Hours to hundredes of years, but typically annual output

Describe input parameters	describe input parameters: Initial longitudinal profile and estimated surface/subsurface grain size; sediment input, including both rate and grain size distribution, and typically at a long-term-avearged basis; and water discharge, typically daily average discharge.
Input format	ASCII
Other input format	A Excel-VBA workbook is available for input data processing and simple error checking
Describe output parameters	Time variation of longitudinal profile, sediment flux and grain size distributions of bedload, surface and subsurface sediment.
Output format	ASCII
Other output format	Output results must be processed with a Excel-VBA workbook
Pre-processing software needed?	No
Describe pre-processing software
Post-processing software needed?	Yes
Describe post-processing software	A Excel-VBA workbook is available to extract the output files into various Excel worksheets.
Visualization software needed?	No
If above answer is yes
Other visualization software

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.

Describe available calibration data sets	See two papers: Cui (2007a) http://dx.doi.org/10.1029/2006WR005330 Cui (2007b) http://dx.doi.org/10.1002/rra.1012 A manuscript with regard to its application to the Waipaoa River, NZ is currently underway by Basil Gomez and others.
Upload calibration data sets if available:
Describe available test data sets	St. Anthony Falls Laboratory downstream fining experiments (Rebecca Soileau, Chris Paola and Gary Parker)
Upload test data sets if available:
Describe ideal data for testing	--

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

 |Extended model description=TUGS is a 1D model that simulates the transport of gravel and sand in rivers. The model predicts the responses of a channel to changes made to the environment (e.g., sediment supply, hydrology, and certain artifical changes made to the river). Output of the model include longitudinal profile, sediment flux, and grain size distributions in bedload, channel surface and subsurface.
