Data from this period were used to test two Coastal and Hydraulics Laboratory 

 numerical models at WES; ADCIRC and STWAVE. The ADCIRC (Advanced 

 Circ ulation) model is a two- or three-dimensional (2- or 3-D) coastal circulation model, 

 and the STWAVE (Steady-state Spectral Wave ) model is a spectral wave model with 

 wave-current interaction. These applications are discussed in Smith, Militello, and Smith 

 (1998). 



1 July -31 August 1996 



This period was selected to include two full spring-neap tidal cycles with all wave, 

 water level, and current gauges operating. The period provided additional data for 

 numerical model validation. During the 2-month period, a storm on 1 1 July had wave 

 heights over 2.5 m, and three other events (on 17 July, 21 August, and 3 1 August) had 

 wave heights exceeding 1 m. Winds exceeded 16 m/sec during the 17 July and 21 August 

 events. The winds during these 2 months show a typical land and sea breeze pattern. 



1 August - 31 October 1997 



This period was selected to coincide with short-term measurements made at Ponce 

 de Leon Inlet. The short-term measurements included current and bathymetry surveys 

 over the ebb shoal, inlet throat, and in bay channels during neap tide (25-29 August) and 

 spring tide (15-19 September) conditions. The short-term measurements also included a 

 72-day deployment (21 August - 31 October 1997) of six additional wave and current 

 gauges located in the inlet throat and in the bay to supplement the long-term wave, water 

 level, and current measurements. Unfortunately, many of the long-term gauges were 

 inoperable. During this time period there were three large wave events: 1 .5-m waves on 

 27 August, 2.3-m waves on 5 September, and waves exceeding 1 m during 8-18 October. 



Scope of Report 



The purpose of this report is to document the available data, document the data 

 collection and processing procedures, and present examples of the long-term field data 

 collected at Ponce de Leon Inlet. These data are currently being applied in CIRP analyses 

 and modeling studies, and it is anticipated that they will continue to be used extensively in 

 the future. Potential users include not only researchers in the CIRP and at WES, but also 

 SAJ, the State of Florida, and others in industry and academia. 



Chapter 2 of this report discusses the types of data collected, the instruments used, and 

 the processing procedures. Chapter 3 discusses examples of the data. Appendix A is a 

 report on current measurements made at the inlet in August and September 1997. 

 Appendix B presents selected aerial photos.
