“The Department of the Interior’s National Interagency Burned Area Emergency Response (BAER) teams conduct analysis of fire effects using aerial and ground reconnaissance methods within the fire areas with the goal of stabilizing the fragile condition of the land to protect life, property, water quality, and ecosystems. Vegetation loss exposes soil to erosion, which could increase runoff and causing flooding. Previous tools developed for the BAER Team hydrologists automated the process of predicting post-wildfire watershed runoff using ArcGIS ModelBuilder utilizing tools within the ArcToolbox. The tools created predict pre- and post-wildfire watershed runoff for a selected rain event are being updated using ArcGIS 9.4 capabilities and updated algorithms.”
