抄録

Six LANDSAT TM images of Lake Suwa, Japan, were processed to extract current patterns. The lake was almost completely covered with Aoko in three summer images. But two spring images, which were after rainfall, showed dispersion patterns of suspended particles from a river. The directions of dispersion were same as local wind at the mouth of the river, but opposite at the middle of the lake. These patterns were compared with current patterns simulated by the numerical two-dimensional lake current model newly developed by the authors. It was suggested that the satellite can observe horizontal circulations in shallow lakes.
