By Rex L. Baum, William Z. Savage, and Jonathan W. Godt

U.S. Geological Survey Open-File Report 02-424

Version 1.0

The program TRIGRS is used to analyze time-dependent rainfall infiltration and slope stability in a digital landscape. The model is primarily applicable to the stability of near-surface, tension-saturated materials. The program is written in Fortran and has been tested on both the Macintosh and Windows operating systems.
