# Book Detail: Gulley and Ravine Control Structures

By reducing the original gradient of the gully channel, check-dams reduce the velocity and erosive power of runoff. Run-off during peak flow is conveyed safely by check-dams. The structures can be either temporary or permanent. … Prevent off-site runoff from flowing across bare soils: use perimeter dikes and diversions.
