Shoreline Stabilization

Description:

Beach stabilization method that enhances natural accretion of sand. The method consists of

installing a drainage system under the beach. The drains are connected by underground piping to

a pumping well landward of the beach, generally behind the dune. Pumps in the well remove

groundwater from under the beach and discharge it into the ocean or bay. The beach within the

influence of the drainage system has a continuously lowered water table. When the water table

under the beach is lower than the water level of the ocean, accretion of sand particles on the

beach slope is observed. Water from incoming waves drains more easily through the dry beach,

leaving a portion of its suspended sands on the beach. As water percolates through the beach,

sands compact, making it more resistant to erosion.

The Stabeach System provides an alternative method of shoreline stabilization to beach

restoration / nourishment.
