On September 6 , 2010, the Fourmile Canyon wildfire started to burn in the foothills of the Rocky Mountains near Boulder, Colorado. Areas burned by wildfires can be expected to have a different hydrologic response to rainfall (as a result of changes in the soil), than before the fire. Boulder County, in an effort to minimize the risk of flash floods in the canyon, aerially applied straw mulch on high-risk areas selected primarily by burn severity and slope (Fourmile Emergency Stabilization Team, 2010). The purpose of this research is to investigate the effects of antecedent soil moisture and impact of straw on the hydrologic response, specifically runoff, of a burned area. Rainfall, runoff, soil water content, and straw runoff were investigated. Straw runoff was defined as the amount of rain that was not absorbed by the straw mulch. Paired plots were used to determine the magnitude of change (in runoff) induced by the addition of straw mulch on the scorched hillside. Volumetric soil water content and storm runoff were measured from two sets of bounded, paired plots (two control and two experimental plots). These plots were calibrated for 35 days starting in June, 2011.
