| Abstract: |
A study was conducted to assess the influence of woody debris on the resistance to flow that may be expected in small, third, and/or fourth order stream channels. A stream site was identified that had naturally matured with growth and debris. Flows were conveyed through the channel, with and without debris, and manning’s n values were determined. The results indicated that the resistance to flow with debris increased nearly 40% over the no debris condition. |
