|Little Topashaw Creek - Experiments - Low-cost channel habitat restoration
Berms or bars of sediment usually form within channels during periods of bed aggradation following incision. Channel widening, and thus bank erosion, continue during this phase. Standard practice for stabilizing these types of channels involves placement of stone structures along banks. This project features the use of bank stabilization structures made from large wood instead of stone. Debris structures were carefully designed to resist displacement by interlocking and anchoring and by inducing sediment deposition. In addition, selected native plant species were used to rapidly stabilize accreted deposits and to create edge-of-field transition zones.
