  • Tidal Bridge Hydraulics
  • Upland Runoff
  • Neglect for large estuaries (use mean daily flow)
  • May influence waterways in very small watersheds
  • Most likely to influence waterways in small urban
    watersheds

  • Tidal Bridge Hydraulics
  • Wind
  • Ocean surge included wind effects
  • Winds over interior waterways reduced
  • Do not use maximum (1-minute) wind
