Abstract

As shown in a number of recent studies, the nearshore bar morphology at Pensacola Beach varies alongshore in response to a ridge and swale bathymetry on the inner-shelf, creating "hotspots" of rip current activity. However, it remains unclear whether these recently identified "hotspots" were present before Hurricane Ivan and if the development of the rip system is a response to the bar cycle. Wavelet analysis of aerial and satellite imagery from 1951 to 2004 was used to quantify the alongshore variation in bar morphology and identify when and where transverse bar and rip morphology develops in response to the storm-driven bar cycle.
