Updates to the models for post-fire debris-flows.
June 2016 - Post-fire debris-flow likelihood estimates are now made with an updated logistic regression model equation. Additional details concerning the new equation, model database, and improvements in model predictions from previous iterations of the likelihood model can be found here.

September 2015 - The analysis methods have been updated to now make calculations and output the results in the UTM NAD83 Coordinate System local to the burn area. This update serves two purposes. First, it allows dissemination of data to end-users in their native reference system. Second, it allows for improved accuracy in our calculations through better preservation of areas and lengths in the input data. This update is effective as of 09/10/2015 and will be a part of all future model runs.
