Sakitsu and Yokaku bays in Amakusa in west Kyushu, Japan, experienced inundation damage in the February 2009 meteotsunami (Abiki) event. The oscillation characteristics of both bays are investigated by taking field measurements and conducting numerical experiments with regard to flood mitigation...

On July 15, 2009, a meteotsunami occurred over Tsushima Strait and flood damage was recorded on the west coast of Tsushima Island. This study investigated the meteorological systems related to that meteotsunami event using surface observation data, grid-point value data, and a mesoscale...

The cost of utilizing kinetic energy of river stream, tidal and ocean current is considered to be higher than that of wind power generation because of difficulties in construction and maintenance of devices installed in seawater. As a solution to the problem, the authors propose a new concept of...

Producers continually need to determine how much of a particular product to produce. As market globalisation has changed their business, their demand uncertainty has become too big and too complex to manage. This study proposes a product's quantitative risk measurement and management model based...

Since the energy of ocean wave exists mostly near the water surface and decreases exponentially with depth, the resource of wave energy is measured in the line density unit (kW/m). Therefore, in the scaling up of a wave energy converter, the captured wave energy increases slowly in proportion to...
