Title: The Effects of Soil Properties, Fuel Characteristics, and Vegetation Recovery on Post-Fire Watershed Hydrology and Sediment Yield in Chaparral Steeplands

Project Proposal Abstract: Accelerated post-fire erosion from southern California steeplands threatens life, property, and infrastructure at the wildlandlurban interface. The Williams Fire of September 2002 provides a unique opportunity to describe and analyze the impacts of fire and historical vegetation management practices on post-fire hydrologic response and sediment yield in chaparral ecosystems. Objectives include 1) quantifying small watershed runoff and erosion response, 2) analyzing the differences in these response variables from watersheds with radically different management-induced pre-fire fuel characteristics, 3) quantifying the immediate post- fire vegetation response from these watersheds with differing pre-fire vegetation characteristics, 4) describing post-fire soil properties and soil water repellency, and 5) describing post-fire soil and bedrock water storage capacities and antecedent moisture conditions. Stream discharge and sediment yield will be measured by refurbishing existing flumes and debris basins. Pre-fire vegetation will be characterized from historical surveys and recent aerial photography. Post-fire vegetation will be measured using point transects and fixed area plots. Soil properties will be measured using standard techniques. Water content and depth of soil and bedrock will be determined using TDR, GPR, and GPS technologies. Information from this research will help land managers assess post-fire watershed response at the wildiand/urban interface.
