Attributes:
• Mostly Laminar Flow
• Visible Structures & Banks
• Maximized Land Accretion
• Easy Maintenance
• Functions Over Wide Range of Flows
Benefits to Nation
• Navigation Channel
• Additional Farm Ground - Aquatic Acres Converted to Farm Ground - Meander Belt Cleared and Farmed • River Valley Protected from Meander - Floodplain Infrastructure Possible - Stable Property Lines, State Boundaries, etc

Chute Lessons Learned
KCD examined the geometry of roughly 25 existing natural and successful constructed chutes to help establish design criteria
• Smooth entrance transitions • Passive, minimal grade control • Constructed width 50-ft min, 75 + preferred, invert < -4
CRP • Chute per River Length Ratio < 1.0 (typically) • Bend Radius of Curvature / Design Width > 2.5 • Minimum Radius of Curvature: 90% > 600’, 2000’ typical • Constructed Sinuosity of 1.0 to 1.2 • Entrance at channel crossing more susceptible to drift • Length greater than 1 channel width
