Evaluating post-wildfire debris-flow rainfall thresholds and volume models at the 2020 Grizzly Creek Fire in Glenwood Canyon, Colorado, USA
As wildfire increases in the western United States, so do postfire debris-flow hazards.The U.S.Geological Survey (USGS) has developed two separate models to estimate (1) rainfall intensity thresholds for postfire debris-flow initiation and (2) debris-flow volumes.However, the information necessary to test the accuracy of these models is seldom avai
