Abstract
Synoptic views from Landsat are useful to grasp hydrodynamic phenomena of large scale of water area. But, Landsat images can only show a temporal scene of the changing phenomena. To compensate this deficiency, numerical simulation should be introduced. This paper show an example to solve this problem through a case study of Ise bay. The authors investigate a relation between the residual current and dispersion of flood water seen on the Landsat image data.Circumstance of the current was examined by computer simulation with finite difference method. The results of this study are summarized as follows: 1) flood water are deflected to the right due to Coriolis force, 2) density current may have an important role for the management of water quality in Ise bay.
