An analysis has been carried out to quantify the sediment transport processes in the Fort Pierce Inlet area and the influence of the inlet. This analysis is formalized as a sediment budget and is based on available survey data, and nourishment and dredging records extending from 1972 to 2002. Available survey data encompass shoreline distances approximately 6 miles north and 15.4 miles south of Fort Pierce Inlet. Three periods were examined in this study: 1972 to 1987, 1987 to 1997, and 1997 to 2002. Average annual sediment volume and shoreline changes derived from the profile data collected during these three intersurvey periods were analyzed. Application of general sediment budget principles established that for the total period 1972 to 2002 there was an average annual deficit of approximately 16,300 yd3/year on the beach south of Fort Pierce Inlet. The general sediment budget indicates that 116,000 yd3/year enter the north boundary of Riomar Beach; 82,000 yd3/year enter the north boundary of St. Lucie County and 57,000 yd3/year leave the south boundary of St. Lucie County. Application of numerical modeling to develop an understanding and predictability of the performance of beach nourishment south of the inlet was carried out as a supporting method to better understand the littoral processes in the area. Recommendations are presented to improve the sediment management practices including sand bypassing to restore balance to the south beaches.
