Geological Framework Study of Follett's Island-Brazoria County

Summary

Texas A&M University at Galveston (TAMUG) will conduct a Geological Framework Study of Follett’s Island and create a data set that will be used to develop a process-based numerical model to predict future beach erosion and morphological changes on Follett’s Island under various storm and hurricane conditions.  This study will include the collection of ultra high resolution swath bathymetry of the Gulf-side of Follett’s Island from 10 to 30 feet of water depth and a series of high resolution beach profiles from the dry beach out to a water depth of 20 feet, to merge with the swath bathymetry. TAMUG will collect CHIRP seismic profiles to document the subsurface stratigraphy of the shoreface and identify potential sand resources. The bathymetry/topography data will provide a base-line data set available in the future to detect change.
