Rising sea levels, coupled with powerful waves and storm surges, contribute to the gradual retreat of beaches and the erosion of coastlines. Coastal structures, including homes, businesses, and infrastructure, are vulnerable to this ongoing threat.
Seawalls and Revetments: Protecting the Shoreline
Seawalls, massive concrete or stone structures built parallel to the shoreline, act as physical barriers to protect against coastal erosion. They effectively absorb wave energy and prevent further erosion of the coastline. Revetments, structures made of riprap (irregularly shaped rocks) or concrete blocks, are placed along the shoreline to dissipate wave energy and protect against erosion.
Dune Restoration and Beach Nourishment: Restoring Natural Defenses
Dune restoration, the deliberate planting of vegetation and reshaping of sand dunes, plays a crucial role in protecting coastlines. Dunes act as natural barriers, absorbing wave energy and mitigating coastal erosion. Beach nourishment, the artificial replenishment of sand along eroded beaches, is another strategy to restore natural defenses and protect coastal structures.
Humid Climate: Navigating Moisture and Ventilation
The humid climate of the Gulf Coast presents unique challenges for building materials, requiring careful consideration of moisture resistance and ventilation. High humidity leads to condensation, which can damage materials and create a breeding ground for mold and mildew.
