| Outline of Final Research Achievements |
We investigated a prediction methodology to assess water quality response to future environmental changes on lakes and reservoirs like climate change. We also developed a aquatic environmental model expressing interaction between ecological factors and water quality in lakes. An analysis method of lake environment using biochemical marker was investigated by using fatty acid. In regard to cycling of nitrogen in lake water body, an analysis method by the use of stable isotopes of nitrogen and oxygen was applied, and we proposed an assessment method of sources and origins of nitrate nitrogen in lake water.
