|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.

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:
