TREX: Two-Dimensional Runoff Erosion and Export
Spatially Distributed Model To Assess Watershed Hydrology, Sediment Transport, and Contaminant Transport and Fate
Welcome to the TREX watershed model web site. TREX is the latest member of Colorado State University's family of watershed models. Using the links to the left or below, you can download: (1) an overview of TREX development; (2) detailed information regarding TREX applications; (3) a user manual; (4) model source code; and (5) example files.
TREX is a reseach tool. Feel free to download model source code and example files. However, it is provided without any explicit or implicit warranty. The authors cannot offer technical support without special arrangements but would appreciate being advised of programming errors. If you use TREX or modify it for your own research, the authors ask that you credit our contribution with the following citations:
