Now Viewing: tetrapodTag type: General "In coastal engineering, a tetrapod is a tetrahedral concrete structure used as armour unit on breakwaters. A tetrapod's shape is designed to dissipate the force of incoming waves by allowing water to flow around rather than against it, and to reduce displacement by allowing a random distribution of tetrapods to mutually interlock." [...] "Tetrapods and concrete have become a Japanese institution in modern times. Their manufacture and dispersal create jobs for Japanese citizens and contracts for construction companies. It is estimated that nearly 50 percent of Japan's 35,000 kilometer coastline has been covered or somehow altered by Tetrapods and other forms of concrete."
