South-facing slopes had the lowest infiltration and showed the highest rates of erosion following the fire. Two years following the fire, ground cover had not yet sufficiently recovered to fully protect either the enorth or south slopes from increased runoff and accelerated erosion. Technical Abstract: The Eighth Street fire had a significant impact on the infiltration capacity and soil erodibility across the Boise Front. South-facing slopes had the lowest infiltration and showed the highest rates of erosion following the fire. Two years following the fire, ground cover had not yet sufficiently recovered to fully protect either the north or south slopes from increased runoff and accelerated erosion. Presented results are consistent with observations made following the September, 1997 thunderstorm where the south-facing slopes had the highest concentration of rills and suffered significant soil losses. |
