| 内容記述 | Matter dispersion due to the shear effect of currents in the coastal waters was analyzed as one of the important mixing dilution processes, and the estimation method of the dispersion coefficient was investigated using an idealized model. The present model is governed by the advective diffusion equation in which the current is given as a solution of the motion equation. The matter dispersion process in both steady and oscillatory currents with the boundary layers is revealed through the analysis of the advective diffusion equations. The difference in the dispersing behavior for both currents, the shear regions of which are respectively characterized by the Ekman and Stokes layers, is also elucidated by the present analysis. Although it is very hard to estimate the practical dispersion coefficient in the steady current because the characteristic time of the vertical diffusion when the dispersion coefficient converges is rather long compared to our daily life time, a practical one in the oscillatory current was obtained in case when the dispersing matter distributes around the boundary layer with a sharp shear because the value is determined by the thickness of the region where the actual characteristic diffusion time is fairly short. | |||||||||||
