Abstract

Spatially-varied hydrologic surface conditions exist on steep hillslopes after timber harvest operation and site preparation burning treatments. Site preparation burning creates low- and high-severity burn surface conditions or disturbances. In this study, a hillslope was divided into multiple combinations of surface conditions to determine how their spatial arrangement would effect erosion. More erosion occurred when high-severity burn conditions occurred above low severity burn conditions. Various hillslope configurations conclude that the spatial distribution of fire severity conditions on a hillslope affects predicted soil erosion rates.
