ABSTRACT: The U.S. Geological Survey debris-flow flume is a unique, large-scale experimental facility located at the H.J. Andrews Experimental Forest in the Willamette National Forest, Oregon. Research on the dynamics of debris flows, landslides, and related phenomena began there in and continues today. Welcome to the H.J. Andrews Experimental Forest The H.J. Andrews Experimental Forest covers the entac (ha) watershed of Lookout Creek, which flows into Blue River Reservoir and then to the McKenzie River. Elevation of the Andrews Forest ranges from 1, to 5, ft ( to m). Broadly representative of the rugged, mountainous. Survey debris flow flume, established in , where the generation and runout of experimental debris flows are studied. H.J. Andrews Headquarters Douglas-fir plantation (clearcut in ). Headquarters site. 3 The Interpretive Trail passes through old-growth forest windfall gap (winter ) and through a clearcut plantation, which. Year Published: Debris flow runup on vertical barriers and adverse slopes. Runup of debris flows against obstacles in their paths is a complex process that involves profound flow deceleration and redirection.

The Andrews Forest, with its long-term experiments and records, provides a focal point for sustaining a long-term interdisciplinary research program, which is critical to solving present and future problems in natural resource management. The purpose of a long-term program of research at the H.J. Andrews Experimental Forest is to develop fundamental .
