 Velocity and Discharge 

 Measurements at Ponce de Leon 

 Inlet, Florida 



This appendix contains a revised copy of a memorandum for record dated 26 January 

 1998, regarding velocity and discharge measurements at Ponce de Leon Inlet, FL. 



Introduction 



Short-term field measurements were conducted at Ponce De Leon Inlet, FL, to support 

 the Inlet Modeling System work unit for development and validation of the circulation and 

 wave model. The subject field investigation, which consisted of two 1-week Acoustic 

 Doppler Current Profiler (ADCP) surveys during the periods 25-29 August 1997 and 

 15-19 September 1997, was conducted by the staff of the Coastal and Hydraulics 

 Laboratory (CHL) at the U.S. Army Engineer Waterways Experiment Station. Results 

 from these activities are discussed herein. Additional information was obtained from 

 several sources. A 2-month deployment of six in situ pressure and two-component velocity 

 gauges (PUV's) was conducted by Florida Institute of Technology. The SHOALS team 

 performed a high-resolution bathymetric survey. Aerial photographs were taken by Aerial 

 Cartographies of America, Inc. of Orlando, FL. Dr. Donald Stauble obtained sediment 

 samples from the interior and exterior of the inlet. Finally, meteorological data were 

 obtained from the Battelle Paint Test Facility adjacent to the inlet. 



The ADCP and bathymetric data surveys were conducted by Messrs. Howard Benson, 

 Thad Pratt, and Terry Waller, CHL. Other participants in the surveys from CHL included 

 Ms. Adele Militello and Dr. Jane Smith. The boat and boat operator were supplied by 

 DIMCO, Inc. 



Bathymetric Survey and Tide Data 



The bathymetric data collected during this effort were not comprehensive and, 

 therefore, do not represent a full bathymetric survey. The bathymetric data were mainly
