TREX: Two-Dimensional Runoff Erosion and Export

Spatially Distributed Model To Assess Watershed Hydrology, Sediment Transport, and Contaminant Transport and Fate

Home

As part of research by John England and Mark Velleux completed at Colorado State University under the direction of Pierre Julien, TREX applications have been developed for:

1. Extreme storms and floods in the upper Arkansas River basin (12,000 km²).  See model extreme flood animation (mpg).
   
   England, J. 2005. Frequency analysis and two-dimensional simulations of extreme floods on a large watershed. Ph.D. dissertation, Department of Civil Engineering, Colorado State University, Fort Collins, Colorado.
    
2. Metals transport at an abandoned mine site in the California Gulch watershed (30 km²).  See model zinc transport animation (mpg).

Additional TREX applications for other sites and processes are under development. In particular, TREX has been applied to the Goodwin Creek Experimental Watershed (Mississippi, USA) and the Naesung Stream watershed (Gyeongsangbuk-do, South Korea). See the Research page for further details regarding TREX applications to other sites and conditions by researchers at CSU and elsewhere.
