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 affect erosion.
More erosion occurred when high-severity burn conditions occurred above low severity burn conditions.
The spatial distribution of fire severity conditions on a hillslope
affects predicted soil erosion rates.
