Section 3: Erosion and Runoff ControlErosion and Runoff ControlNorth Carolina Forestry BMP Quick Reference Field GuideWays to Prevent Erosion and Sedimentation:Retain groundcover surface flow of Runoff -- Don't let it funnel or sediment from re-vegetate critical bare soil overall soil Runoff can be as easy to remember as: Slow it and, Spread it down the it can pick up speed. Running water is a tremendous Erosion force. If you slowthe Runoff , soil Erosion will be greatly out the keep it from concentrating or funneling together. Spreading out the force of the water Runoff will make it more likely to soak into the soil, instead of forming gullies or trenches atop the ground Steps for Controlling Erosion and Runoff :1. Maintain groundcover so Runoff can soak into the Prevent Runoff and Control Runoff as it Capture sediment contained within the :Keep the sediment and associated nonpoint source pollution out of the water!
Broad-based dips Turnouts Cross-drains (Ft) Waterbars (Ft) 20+ 16-20 11-15 6-10 0-5 60-40 100-60 140-100 180-140 250-180 40-30 60-40 80-60 100-80 120 -100 This table may first appear to be backward. But, it is laid out this way to remind you that steeper slopes usually require closer spacing between erosion control structures.
