Abstract

Hillslope Toolbox to Support Post-Wildfire Erosion and Sediment Models
Track: Wildland Fire Management
Authors: Jennifer Schmidt, GISP

Wildfires often increase sedimentation and erosion, and accurate predictions of post-fire sediment yields are critical to assess potential impacts on valued resources and assist in treatment decisions. This paper focuses on the step-by-step toolbox Herrera developed using ModelBuilder and Python to allow land managers to automate extracting hillslopes from DEM data. The output is imported to the Forest Service Disturbed WEPP and ERMiT erosion and sediment delivery models and run for large areas.
