Sydney近郊のManly海岸の現地踏査とそれに基づく2, 3の考察

抄録

Field observation of the Manly Beach in the suburb of Sydney in Australia was carried out to investigate coastal zone environment. Coastal zone in this area has a much better environment compared with the Japanese coast, much of which is covered artificially by concrete blocks. One of the utilizations, which is new in Japan, is the natural pool built at the corner of the pocket beach. This is a good idea in order to create safe, natural recreational zone for swimming and it may be introduced in Japan. Improvement method in building gently sloping revetment is discussed.
