Post-wildfire Curve Number Estimates for the Southern Rocky Mountains Data

This data repository documents the input files, output files, and RStudio script files used to generate the Curve Number (CN) regression analysis performed for a U.S Army Corps of Engineers and U.S. Geological Survey study investigating the post-wildfire CN estimates for the Southern Rocky Mountains. For this CN analysis, streamgage data for runoff events within 77 burned watersheds in Colorado Rocky Mountain region were used to quantify CN values and changes in CN values from pre- to post-wildfire conditions. Various watershed characteristics (slope, elevation, northness, and eastness), percent watershed area burned, and land cover type were used to develop predictive models that provide estimates of post-wildfire CN changes. These models could be used to inform additional post-wildfire assessments within the region.
