ABSTRACT:This report presents results of inspections of rubble-mound coastal structures monitored previously under the Monitoring Completed Navigation Projects (MCNP) Program. Expedient, low-cost walking inspections were performed at 11 sites. Positions of breakwater and jetty armor units were compared with their positions in previous aerial photography and photogrammetric surveys. Settlement of portions of the structures as well as voids in their armor cover also was noted, and photographs of the structures were obtained. Summaries of inspection results as well as recommendations are presented in this report. The work was conducted under the "Periodic Inspections" work unit of the MCNP Program.
