Fire Enhanced Runoff and Gully Initiation (FERGI) Model
The FERGI model is used by a relatively small number of BAER team members in Region 4 (2%) (Foltz and others 2008). The FERGI model is a physically-based mathematical description of hillslope hydrologic and geomorphic response to a set of weather events, and the model is applicable to any part of the western United States. FERGI estimates the probability of post-fire rainfall excess (mm), runoff generation amount (m3 s-1 m-1), and gully initiation positions (m) on hillslopes with and without mitigations using contour felled logs/log barriers.
