Tokuzou HOSOYAMADA
In recent years, global environmental change due to human activities, global warming is becoming a problem in particular, concerns have been raised also make a significant difference in aspects of the coast. Is becoming necessary to make an effort in the face with such problems, in recent years to preserve the marine environment, maintain and improve the productivity of coastal ocean in the future while preventing the disaster ocean, in the target area in order to clarify the various processes is to understand the mechanism of water flow is needed.
Is an important base to represent the Northeast also commercially, such as that of Sendai Shiogama harbor waters around Sendai Bay is the only certain major ports in the Northeast.
Leisure Development in Sendai Bay coast, due to industrial development, was launched by the wave and current garbage diffusion of contaminants often found in the coast has been confirmed than ever before. These waste had become a major problem in coastal Sendai Bay.
In this study clarify the mechanism of flow of the waters around Sendai Bay was considering using a multi-layer model two-dimensional plane, affecting the flow of the sea, the element currents, current due to wind, and tidal flow in order to solve such a problem We intended to.
Spread of contaminated water were calculated using the results of particle tracking and analysis, was a virtual floating trash in the waters around Sendai Bay also. Made it clear trend and diffusion behavior of airborne dust floating in the waters around the Gulf of Sendai as a result
