Hard engineering strategies - advantages and disadvantages - Coastal She quotes a man, whose website displayed several kinds of tetrapods: Why did I come to like such a thing? The well-prepared mainstream visitor to Okinawathe kind who pores over standard travel guides and promotional materialwill likely know about the famed hoshizuna (star sand), minuscule exoskeletons of a tiny marine organism. Tetrapods have been instrumental in the protection of the coast and many tourist attractions for a number of years. For the past seven years, he has marketed a stuffed Tetrapod made out of nubby grey felt, allowing people to bring a little piece of the concrete seaside into their own home. Labeled compensation politics, these funds appear to many as de-facto bribes in exchange for hosting U.S. bases. The manifestations of this love are too numerous and too variedand too fascinatingto present a full survey here, but I would like to conclude by introducing this phenomenon as a next-stage evolution of tetrapod-generated ecologies, moving onto land and inhabiting the world of popular culture and consumer goods in which tetrapods have become cute and cool. I even think that its in human beings nature to be attracted to such things (quoted in Wijers-Hasegawa 2007). Many ana-zuri enthusiasts appreciate the opportunity to fish for species that would otherwise require a boat to reach their natural habitats, but tetrapod critics claim that the fish drawn to tetrapods for shelter and to feed on the smaller marine life also drawn to tetrapods are often invasive, upsetting natural ecologies. Or, as graphic designer Kobayashi Ryo explained, Tetrapods are massive and practical but at the same time sexy when you look at their curvilinear beauty. Fudo Tetra sponsors educational events to familiarize children with tetrapods, including the opportunity to make your own miniature concrete specimens (figure 31). Introduction: Tetrapod are organisms that have four feet. Advantages - Builds up a large beach which, as well as providing protection from erosion, can attract tourists. Coastal Dune Protection and Restoration | Coastal Processes, Hazards (Tetrapod, iPod, get it?) 2018. 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. [18] The dolos, which is shaped like an H twisted 90 degrees at the center of the crossbar, has South African origins. Nakagusuku-wank wank kanky hozen keikaku ni kansuru akushonpuran [Action plan concerning the Nakagusuku Harbor port environmental protection plan]. yama extends this sense of moe to industrial forms, including tetrapods. [24] He gushes about the functionality, soundscape, and construction of tetrapod walls, noting they are randomly assembled together with the same shapes. The Google Maps satellite photo of the overtly engineered public Zanpa Beach and adjacent private Uza Beach (restricted to guests of the Okinawa Zanpa Misaki Royal Hotel and Uza Terrace Beach Club) clearly reveals the pattern of the longshore drift generated by waves off the East China Sea and the corresponding buildup of sand against the groin on Zanpa Beach. Under contemporary conditions of advanced consumer capitalism in a country chock full of technological knowhow, design sense, artistic creativity, ardent hobbyists, tinkerers, and aficionados of all things cute, the transformation of this coastal armor unit into art piece, plush toy, brand logo, and object of desire should not be, upon reflection, too surprising. Naha: Okinawa-ken. Okinawa-ken. Tokyo: Nihon Shha Nagatame Burokku Kykai. [4] The fascinating details of the physics, engineering, and economics that make tetrapods such a successful and elegantly simple design are beyond the scope of this article. [3] A major French naval base, Mers-el-Kbir gained notoriety for the British Royal Navys attack on it July 36, 1940, to liquidate the French fleet before it fell into German hands after the fall of France the previous month. In this kind of deployment, the most visible material is the more natural-lookingbut more erosion-pronequarried natural stone that forms the foundation of the visible structure, while the potential eyesore of the concrete tetrapod armoring is practically invisible from the beach. . A marker for the Grave of Amamichu (a female deity credited, along with her partner, Shirumichu, with creating the first inhabitants of the Ryukyu Islands) on one of the outcroppings drew my interest, but I ended up spending far more time on the other outcropping where the lifeforms among the tetrapods stacked along the outer wall of a wide concrete extension captured my attention (figure 20). With limited local timber suitable for construction and a rise in prices in the mid-1960s for timber imported from mainland Japanlimited by U.S. policy on Japanese business in Okinawaconcrete became more cost-effective than timber. This message is overt in the first full foldout spread featuring wave blocks such as tetrapods, humans, and nature flourishing together in safety; it claims that wave block installations rejuvenate ruined nature as they simultaneously protect against natural disasters made increasingly more frequent and extreme by climate change and other human impact (figure 28). After that night, I began to wonder about the capacity of tetrapods to create new, unplanned habitats, and started to seek out creatures who have adapted to living with them.
