Abstract

lncreases in annual streamflow and peak streamflows were determined on four small watersheds following timber harvesting and road building. The measured hydrologic changes are compared to those predicted by a methodology commonly used in the Forest Service's Northern Region, the equivalent clearcut area procedure. lncreases in peak streamflows are discussed with respect to their potential to modify the channel system.
