Sedimentological Characteristics and Internal Architecture of Two Overwash Fans From Hurricanes Ivan and Jeanne
Extensive overwash occurred along the Florida coast during the passage of four strong hurricanes in 2004, providing an excellent opportunity to study the spatial patterns and sedimentary architecture of washover deposits. Detailed 3D sedimentological characteristics of two of the overwash fans were...
