STREAM RESTORATION FOR FLOOD DAMAGE REDUCTION IN THE RED RIVER - Technical Paper No. 5

The proposed approach for restoration of streams as a flood damage reduction approach would involve: 1) reconstruction of the channel using dimensions, patterns, and profiles derived from stable reference reaches in the watershed and regional reference data for stable stream reaches (Appendix), or by reconnecting isolated oxbows if present, 2) revegetating the riparian corridor and stabilizing the new stream banks by establishing bank vegetation and, where appropriate, using tree revettments or rock vanes as described by Rosgen ( 1996), 3) construction of setback levees outside of the meander belt with top elevations corresponding to a 10 year event, 4) optional construction of off-channel storage areas outside the levees.
