抄録
Bottom sediment processes in Lake Biwa are discussed by testing a number of vertical profiles of water temperature and turbidity. Vertical diffusion in the shallow South Basin strongly depends on the diurnal thermal stratification and resuspensions of fine sediment become significant during the destratification. This mixing mechanism was verified by a numerical model assuming the uniform sediment, with an aim to include more general bottom fluxes. The boundary mixing in the shallower basin causes horizontal transport into the deeper part, due to wind-driven density currents and gravitational intrusion along the seasonal thermocline, which results in final settling in the deeper North Basin. Turbid intrusive layer is also formed by lifting the presuspended sediment in the preceding ebbing phase of basin scale internal seiching, in the upwelling phase of the thermocline.
