About Rip Currents:

  • Definition: Strong flows of water running from a beach back to the Open Ocean, sea, or lake.
  • Coastal Hazards: Among the most well-known coastal hazards on beaches worldwide.
Formation:

Beach Topography Influence:

  • Formed by the topography of a beach, whether it’s hard-bottom (rocky) or soft-bottom (sand or silt).
  • Includes both outside and inside water areas, encompassing dunes, marshes, sandbars, piers, and reefs.
  • Rip currents often form around gaps between sandbars, piers, or parts of a reef.

Wave Obstacles:

  • Underwater obstacles, like sandbars, piers, and reefs, block waves from washing directly back to the sea.
  • Feeder waves, water from these waves, run along the shore until finding an opening around the obstacle.
Function:
  • Object Movement: Rip currents do not pull a person down or hold them underwater.
  • Floating Objects: They carry floating objects, including people, just beyond the zone of breaking waves.
