Road-related erosion from the February 1996 flood in the Lookout Creek and Blue River watersheds, Oregon

DB Code: 
GE008
Abstract: 

Studies of the effects of forest roads on mountain watersheds (e.g. Jones and Grant 1996; Wemple et al. 1996) led to asking how sedimentation processes were affected by roads during the flood of February, 1996. Of interest were how roads influenced erosional processes and how flood-induced erosion affected the transportation network. By employing concepts of sediment budgeting and disturbance cascades, this study aims to create a landscape context for understanding the impact of an extensive road network on the geomorphic imprint left by this flood of record in February 1996.
