Beach Recovery and Hurricane Impact Mapping in Florida
August 2024 – Beach recovery is in the focus of EOMAP’s talk at the ASBPA – American Shore and Beach Preservation Association Conference 2024 (26-29 August) in Texas. The satellite-based mapping solution perfectly matches this year’s ASBPA conference motto: “Wrangling the Waves of Change: Adapting to Coastal Dynamics”:

“Analysing nearshore change at Coquina Beach following Hurricane Idalia” is the title of EOMAP’s presentation. Coastal engineer Edward Albada and Innovation Manager Kim Knauer outline how EOMAP physics-based Satellite-Derived Bathymetry (SDB) helped assess the beach and nearshore change after nourishment measures in 2021 and the hurricane “Idalia” in Florida in August 2023.
For this purpose, two (a pre- and two post-hurricane) SDB snapshots from Planet’s SkySat imagery in 3m horizontal resolution were compared against APTIM’s single sideband (SSB) profile data.
The results indicate
đź“Ť physics-based SDB as a viable option for local and federal regulatory agencies
đź“Ť who are interested in rapid, cost-effective, and accurate bathymetric surveys following episodic storm events.
đź“Ť The SDB comparison allows for a direct assessment of spatial changes within the domain, including sandbar dynamics and smothering of hard-bottom features.
đź“Ť The comparison in dense spatial grids also allows for a better understanding of the nearshore dynamics and beach response for potential application in morphological modeling applications.
