Abstract:

The purpose of the report is to provide information which can be used to better protect present and future cable landings at the PMRF. Information need for proper design of cable protection includes wind data, wave data, nearshore current estimates, longshore and onshore-offshore sand transport estimates, and geotechnical data. The National Climatic Data Center has provided summaries of six years of wind data collected at the PMRF. Wave data are less abundant and are contained in several sources the wave climate put together by Marine Advisers 1964 the daily visual observations made at the PMFR since 1968 and an offshore wave gage installed in October 1982. Limited nearshore current data are available from several references. Geotechnical information was particularly scarce so a program of data collection was planned and executed. Three 30-foot borings were taken on the beach to provide information primarily about the depth and strength of the beachrock indigenous to the PMRF cable landing area. In this report, the climate of the study area, including precipitation and temperature, is discussed. Wind and wave data are tabulated and analyzed with directional and seasonal trends identified. The geology of the region is briefly summarized with particular emphasis on beachrock, which seems to be the indirect cause of most of the cable problems. The sediment budget is described and includes an identification of sand sources and sand movement directions. The conclusion include a summary of design considerations and some recommendations for future work.
