Abstract:

This report presents results of a monitoring program designed to evaluate the effectiveness of a prototype void and sand-sealing operation. The Port Everglades south jetty is a rubble stone structure with large man sized voids. Beach Fills place south of the structure eroded at an extremely high rate, indicating that material was being lost through the structure into the entrance channel, where it was thought to be a contributing factor to navigation channel shoaling. Sealing of the structure with sodium silicate-cement for filling void cavities and with sodium silicate-diacetin for stabilizing sand- filled voids within the structure formed a barrier to sediment infiltration. Four site visits were performed as part of the monitoring program a reconnaissance trip, b preconstruction experiment, c during construction inspection and observation, and d postconstruction experiment. The transmission of dye and current meters in structure voids indicated net flow through the structure before and after construction sealing. The tests indicated that the structure was less transmissible in the postconstruction condition.
