Abstract
It is necessary to grasp the behavior of the river water which gives pollution load, because of the design of the water quality improvement policy of Tokyo Bay where the deterioration advances. So this paper examined the flow characteristic of river water around the head of the Tokyo Bay in the flood using numerical simulation and satellite image. First, the pattern of advective diffusion of the river water was caught from LANDSAT image, and second it was simulated numerically by MEL3D which is a three-dimensional model. As the result, flow pattern of the surface layer which has appeared in the satellite image was recreated well with MEL3D. Finally, the relationship between hydrologic and meteorologic condition and behavior of river water was examined by the calculate condition systematically changing, it was shown that the flow of surface which is generated by the wind around the head of Tokyo Bay influenced the advective diffusion of the river water.
