Geomorphically-Based Roughened Channels
Channel constructed steeper than the adjacent channel (profile control)
Based on morphology of steeper stream channel
Stable engineered streambed material (ESM)forms channel bed & banks
Quazi-hydraulic design for target species/lifestages(velocity, depth, drop, EDF)
