USE OF FLUVIAL PROCESSES TO MINIMIZE ADVERSE EFFECTS OF STREAM CHANNELIZATION
Stream restoration is a means for restoring flow efficiency in streams that have become debris-choked and eroded due to the direct or indirect actions of humans. Such degraded streams are typically characterized by debris jams, severe bank erosion, overwide channels, and heavy sediment discharge brought on by altered stream regimes, land use changes or prior channelization. Stream restoration is accomplished by removing debris jams and providing fairly uniform channel cross-sections and gradients while preserving meanders, leaving as many trees as possible along stream banks, and stabilizing banks with vegetation and riprap where necessary. Economically, the cost of restoration is typically less than one-tenth of the cost of channelization. Experiments with stream restoration on Briar Creek, Gum Branch and Mallard Creek in Charlotte, North Carolina, have been extremely successful.
