  • Beach erosion prevention jetty configuration
    Patent number: 4498806
    Abstract: A beach erosion jetty configuration is provided wherein the jetties are curved to stop or prevent a vacuum effect which causes beach erosion. Swift currents running in or out of inlets create a Venturi effect that pulls sand-laden waters from nearby and sometimes distant shorelines, and in accordance with the present invention jetties are provided with curved ends that negate the loss of precious sand. Such curved jetties function as erosion control devices and actually stop and prevent erosion.
