Research Abstract |
For clarifying transport processes of sediments settling from outside of Lake Biwa, we studied a fluctuation of sediments flowing from lake outside and time variation of water temperature near the boundary of lake-bottom and of temperature in lake sediments. Although the fluctuation of sediments well corresponded to monitoring data of the wind around Lake Biwa, its year-to-year trend was different. On the bottom of Lake Biwa, water temperature near the lake-bottom was higher than the temperature above it. Temperatureof the sediments below lake-bottom was also higher than the temperature near the lake-bottom. Spectrum analysis showed the possibility that an increase of water temperature near the lake-bottom could partly be induced by increasing the temperature of lake sediments.
