  14. SUMMARY AND RESULTS

  15. The shoreline change modeling component of the St. Johns County, Florida Hurricane and Storm Damage Reduction Feasibility Study developed and calibrated a GENESIS model for the study area (R-84 in South Ponte Vedra Beach southward to R-121 in Vilano Beach north of St. Augustine Inlet). • The study applied the GENESIS model within the GenCade regional sediment management tool developed by the USACE ERDC. • The calibrated and verified GENESIS model results agree well with measured beach volume changes during the calibration period (July 1986 to January 1999). • The model produces reasonable agreement with measured volume changes during the verification period (January 1999 to August 2007) • Additional model simulations documented the calibrated and verified GENESIS model sensitivity to selected model parameters.
