NOTES:
1. Depth of flow based on minimum gratle.
2. Velocity based on maximum grade
3. Riprap based on Pader method times 2.
4. Flow velocities in channel sections above 18% will be controlled using check dams. Check dam locations
will be determined in the field. Check dams will be constructed from wood and/or rock.
