News: Connecting Erosion to Flooding

Model Predicts Storm Impacts on Beaches and Dunes

ncsg

During storms, strong waves and currents can erode beaches and dunes and create low-lying areas vulnerable to flooding. We use field surveys and a computer model called XBeach to predict this erosion, as well as to understand its interactions with storm-driven flooding of larger regions.

Computer models allow us to see how the storm surge and waves impact the beach over time, and which locations are vulnerable to large-scale damage. Good predictions of such storm impacts help emergency managers take better-informed measures to protect coastal areas. Understanding vulnerabilities also instructs highway access design and residential area planning.

We used the XBeach computer model on more than 30 kilometers of Hatteras Island between Avon and Rodanthe to explore how to connect erosion predictions to larger areas. Could XBeach cover more of the island, yet still provide good erosion predictions at beach and dune scales? And how could we connect erosion predictions to other models for storm surge and flooding?

Alireza Gharagozlou wins Student Educational Award

Ph.D. student Alireza Gharagozlou won the Student Educational Award at the ASBPA National Coastal Conference 2018. This award is given annually to an undergraduate or graduate student who, through his or her research, is furthering the state of the science of coastal systems as it relates to the goals and mission of the ASBPA. Congrats to Alireza!

Alireza accepts the Student Educational Award during the awards luncheon at the ASBPA National Coastal Conference.
