This includes birds, animals, and humans. Advantages - Builds up a large beach which, as well as providing protection from erosion, can attract tourists. The advantages of Betonblock tetrapod moulds. Not too long after this interview, on February 15, 2008, yama posted on the popular website Daily Portal Z patterns and photos for making a tetrapod from a sheet of paper. The weight and interlocking design of tetrapods work effectively against extreme weather conditions, dissipating the force of the water well.

Founded in 1967, six years after the incorporation of Japan Tetrapod, the NSNBK states its goals as follows: The Associations activities aim to conduct research surveys of construction technology related to civil engineering that uses wave-dissipating blocks, to work diligently on construction methods and technology, and to contribute to the preservation of national land and the improvement of the environment, thereby improving the everyday life of the national citizenry.[16]. There do appear to be genuine efforts in the industry to work toward greener coastal engineering solutions, but public relations campaigns are already very green now. Okuyama, pictured here with a colleague from the Sendai Bay South Coast Office, proves there is a lot of literature on the topic. Coastal management - KS3 Geography - BBC Bitesize - BBC Bitesize The dispersal of backflow water pressure was precisely one of the aims of Danels tetrapod design; his experiments indicated that a semi-open structure of heavy, interlocked, rough rounded forms was superior to surfaces of flat concrete slabs and square concrete blocks in dispersing wave energy while standing up to water pressure.
