Streamflow Responses to Road Building and Harvesting: A Comparison with the Equivalent Clearcut Area Procedure

摘要

Increases 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. Increases in peak streamflows are discussed with respect to their potential to modify the channel system.
