  • Depth for no vegetation
  • Manning's N, with vegetation
  • Roughness coefficient
  • Minimum Manning's N
  • Maximum Manning's N
  • Set Defaults
    • Opens the Roughness By Depth Defaults dialog. Defaults from several Army Corps projects can be automatically entered into the Roughness Options dialog.
