Most are based on an area within 60 to 200 kilometers of the shoreline and may include coastal floodplains, coastal forests called mangroves, marshes, and tideflats (coastal areas affected by the rise and fall of the tide), as well as beaches, dunes, and coral reefs. The predominant strategies used to counter these problems are Seabee walls, Seawalls, and also signage, bins and fences; and these five solutions each have advantages and disadvantages, which ultimately prove whether or not, the strategy itself is successful. Dept. Because of the cost involved, beach nourishment is only used where other strategies prove to be ineffective. Seawalls can be made of concrete, rocks or wood.
