Abstract: Purpose: This Coastal and Hydraulics Engineering Technical Note (CHETN) describes the use of lidar data in conjunction with beach profile surveys to examine morphologic and volumetric change on a regional scale. The study area includes three counties and over 70 miles of the southwest Florida coastline. The lidar data were obtained from the U.S. Army Corps of Engineers (USACE), Joint Airborne Lidar Bathymetric Technical Center of Expertise. Beach profile surveys were provided by USACE Jacksonville District (SAJ), University of South Florida (USF), and Coastal Planning & Engineering (now CBI Industries, Inc.). The study region is entirely within the SAJ jurisdiction. The area of interest includes the coastline along the Gulf of Mexico from Clearwater Beach in Pinellas County, FL, to Venice Beach in Sarasota County, FL (Figure 1). Active Federal projects existing within the limits of this study region include the Pinellas County Shoreline Protection Project (SPP) (USACE SAJ 2010), Tampa Harbor Navigation Project (deep draft), the Gulf Intracoastal Waterway (GIWW), Manatee County SPP at Anna Maria Island, the City of Sarasota SPP at Lido Key, Sarasota County SPP at Venice Beach, and a number of federally authorized shallow-draft navigation channels. Local projects exist as well at Longboat Key and at Siesta Key. This effort was supported by the SAJ and the U.S. Army Engineer Research and Development Center (ERDC) through the USACE Regional Sediment Management (RSM) Program.
