Beach slopes of Florida: Bradenton Beach to Clearwater Beach
By Jacquelyn R. Overbeck and Kara S. Doran
USGS, St. Petersburg, Florida
Summary
The National Assessment of Coastal Change Hazards project derives features of beach morphology from lidar elevation data for the purpose of understanding and predicting storm impacts to our nation's coastlines. This dataset defines mean beach slopes along the United States Southeast Gulf of Mexico from Bradenton Beach to Clearwater Beach, Florida for data collected at various times between 1998 and 2010.
