At the coastal area which is the boundary between the land and the sea, in addition to the existence of abundant biological resources, various human activities such as habitations, port works, recreations and fisheries are conducted. At the same time, the costal region is often exposed to threats of the natural disasters such as tsunamis, storm surges, and beach erosions. Therefore, it is a big problem above all to protect the lives and the properties from such natural disasters.
In the coastal and ocean engineering laboratory, the basic technologies for human benefit are studied through pursuing the action principle of nature such as the coastal waves incoming from the ocean.
Recently, we focus on studying the sea surface wind that generates waves. We also focus on meteorology so as to assess the influence of global warming to the coastal area.
Field observation on wave run-ups and splashes at a breakwater: This photo shows a large wave run-up and a large amount of splashes generated at a vertical breakwater. The seawater splashes and much smaller spray are transported and diffused by strong winds. Consequently the salt damage, e.g. the corrosion of reinforced concrete structures, the withering of crops, etc., is caused in wide area.
