21 The Spring Brook Stream Meander Project Create normal entrenchment condition. Create geomorophologically appropriate meanders. Plan, profile geometry and bed substrate to prevent channel incisement. Channel and floodplain geometry mimic natural features and move flood flows. Natural material bank revetment and bed substrates to improve lotic diversity. Establish native riparian species with continuity to preserve restoration plans.
