Oyster Castles to Elevate Old Reefs

Oyster Castle Reefs for Coastal Resilience

Average reduction in wave heights across all reef sites when water depths are greater than mean site depth (1.0 to 1.5m) was 0-20%, whereas for shallow depths (0.5 to 1.0m) the average wave height reduction was 30-50%.
