What is the purpose of jetties at the beach?
Jetties are another type of shore perpendicular structure and are placed adjacent to tidal inlets and harbors to control inlet migration and minimize sediment deposition within the inlet. Similar to groins, jetties may significantly destabilize the coastal system and disrupt natural sediment regimes.
What problems do jetties cause?
Due to their perpendicular-to-shore placement, jetties can disturb longshore drift and cause downdrift erosion (As a mitigating action, sand building up along the jetties can be redistributed elsewhere on the shore.) The longer the jetty is, the greater impact it has on adjacent areas.
