P.E.M. Beach Project

Project 1:  P.E.M. Technology (Pressure Equalizing Modules):
The installation of the P.E.M.s is complete as of Thursday, February 28,  2008.  Here is a brief description of the project: 
The project is a test designed to evaluate a system that alters water     pressures within the sediments in an effort to increase sediment     deposition on the beach. Each module is a 2.5-inch diameter, 6-foot-long     tube with drainage slots. The modules (tubes) have been placed vertically in the sand with the distances between the existing grade to the tops of the buried tubes ranging from 12 to 24 inches, depending on the tube’s location along the beach face. PEMs have been installed in 33 rows perpendicular to the shoreline and spaced ca. 50 meters apart along one    mile of beach. The PEMs have been installed ca. 10 meters apart within each row beginning from the mean low water line (MLWL) and extending to the toe of the dune or to structures that armor the shore. In plan view, the    cumulative amount of space occupied by the PEMs is expected to be    approximately 4 square feet over 13 acres, but the Town expects the    PEMs  to affect the entire 13 acres. The modules have been installed by a    small earth drill mounted on tracks or by a backhoe with a drill mount. An   optional installation method included hydraulic jetting.
