Eng. At the same time, coastal zones are subject to intense use by humans-for transportation activities, resources and energy extraction, industrial uses, and recreation. Rev. If this does not resolve the issue or you are unable to add the domains to your allowlist, please see this FAQ. Japan is a series of volcanic island arcs on the northwestern margin of the Pacific Ocean. Coast. Geosci.)

Toward Integrated Coastal Management in Japan - Nautilus From seawalls and embankments to wave-dissipating blocks and breakwaters, concrete has been used as the principal line of defense against the forces of the sea throughout the postwar period.

August 31, 2022 Remote Sensing Coastal Change We use remote-sensing technologiessuch as aerial photography, satellite imagery, structure-from-motion (SfM) photogrammetry, and lidar (laser-based surveying)to measure coastal change along U.S. shorelines. 133, 126141 (2018). Yet, how sandy coasts respond to these basin-scale changes has to date been limited to a few long-term beach monitoring sites, predominantly on developed coasts.
