Armoring involves building revetments, seawalls, detached breakwaters, groins, etc. Such structures include seawalls, gabions, breakwaters, groynes and tetrapods. These structures included seawalls and revetments or sand-trapping structures such as groynes. Coastal bulkheads are most often referred to as seawalls, bulkheading, or riprap revetments. Structures that run parallel to the shore (seawalls or revetments) prevent erosion. The construction of seawalls and breakwaters reduced the power of waves at some locations. On Upper Matecumbe Key, major damage to revetments and close to of concrete seawalls occurred. It can be used for retaining walls, bridge abutments, seawalls, and dikes. The fortifications include castles, forts, towers, Martello towers, artillery batteries, and seawalls. The bulkhead of the pier was washed away, while docks and several seawalls were damaged. There are mangrove islands as well as miles of canals bounded by seawalls. With the help of locals, Clark, gathered information about tides, beach composition, mudflats, and seawalls. It is punctuated by numerous seawalls cutting the shore. Elsewhere, in Lantana, large waves sweeping over seawalls went on to destroy a lifeguard tower. Finally, the anchorage was small and the harbor was surrounded by tall seawalls.
