Beach replenishment- climate infrastructure can do more than protect


Artificially enhanced beaches are a very real and viable alter- native to disappearing coastlines. Man-made beaches involve extending the existing beach or creating a new coastline. Mate- rials matching the local character (e.g. appropriate consistency of sand and native tree species) are used to give the appearance of a naturally occurring beach. Man-made beaches can be economically beneficial by boosting tourism, and can also create a barrier against rising waters or high waves. Beaches can also be nourished, to prolong their lifespan. By adding natural sediment to widen the beach, the distance from storm surge to developed area is increased, reducing the likelihood of destruction. Sediment in nourishing projects is usually acquired from nearby areas. Special care must be taken to prevent these areas from being overly eroded, while ensuring coastal life remains safe.
