Revealing Sediment Transport Pathways and Geomorphic Change in Washover Fans by Combining Drone-Derived Digital Elevation Models and Single Grain Luminescence Data

Simon Matthias May, John Nikolaus Callow, Dominik Brill, Dirk Hoffmeister, Jan-Hendrik May



Chronostratigraphic investigations on coastal sedimentary records such as washover fans or beach-ridge sequences may be used to reconstruct storm chronologies on centennial to millennial time scales. However, modern analogs are pivotal in interpreting depositional processes and reducing uncertainty in evaluating the complex chronostratigraphic architecture of these landforms. Such a modern analog was provided by category 3 tropical cyclone (TC) Olwyn in 2015, which caused a significant storm surge in the Exmouth Gulf (Western Australia). Pre- and post-TC Olwyn geomorphological surveys and high-resolution drone-derived topographical data of a large washover fan document a detailed history of ..
