 note = {The diffusion of river water flowing into the south basin of Kagoshima Bay was investigated using Landsat-5 / TM 6-th band images. The numbers of images used were 8 for Kohtsuki R. and Honjyo R. and 9 for Nagata R. and Okawa R. from 1984 to 1994. The main results are as follows : 1) The averaged diffusion area and diffusion distance are almost proportional to the annual flow amount. 2) As the flow amounts of Kohtsuki R. and Nagata R. are small, sea water flows up into the rivers at hightide. At lowtide, river water flows to the southern direction along the coast. The diffusion distances are shorter than 0.8 km at hightide and about 1.6 km at lowtide. 3) The flow distance of Okawa R., which has a relatively large flow amount, is about 2 km, but often runs up to 4 km. 4) The tidal flow effect on the direction of the river water diffusion is large for the long distance and small for the short distance. For the long distance, tidal flow direction within 1 hour affects the diffusion direction. 5) For Honjyo R., the river water diffusion is complex and can not be explained by the tidal flow or wind direction. Constant residual flow and/or the stratification of the sea water must be taken into account.},
