Engineering study recommends hybrid dune‑and‑wall wave mitigation, models show reduced wave force and scour
JR Evans presented island‑wide modeling that shows hybrid nature‑based dunes plus a landward wave mitigation wall could reduce wave heights by roughly 30% and damaging force by ~50% in 100‑year storm scenarios; continuous funding and permitting strategies were discussed.
The full story
JR Evans coastal engineer Austin Wise summarized hydrodynamic and sediment‑transport modeling that evaluated wave‑mitigation options across the island. "The damage from coastal flooding is often a direct result of wave action," he said, explaining the team modeled 100‑year storm conditions and site‑specific scenarios including short, property‑scale walls and longer continuous alignments.
