Research Abstract |
Methods for quantifying and evaluating the material dynamics in lakes and their watersheds were developed using the vertical distributions of materials and isotopes, the contents of particulate matter in inflowing rivers during rainfall periods, the isotopes in surface and groundwater as the tracers on time scales, sources, and processes. The regime shifts in water quality and ecosystems were detected in Lake Kasumigaura and then their causes were discussed.
