Abstract:

Degraded headwater streams are common in the mountainous West. They have experienced a variety of stresses from public and private uses and will require specific management consideration to recover during continued use. It is generally recognized that deposited sediments are required for the natural rebuilding of streambanks. This study evaluated the effects of vegetation lengths and other attributes in entrapping and retaining sediments on a simulated stream reach in the Hydraulics Laboratory at Colorado State University. Loading and flushing of sediments was a function of vegetation characteristics and stream discharge.
