| Outline of Final Research Achievements |
Background to the water environment problems in the Hokkaido region includes snow falling and melting unique to cold regions, ice formation / deicing of rivers and lakes, which complicates material dynamics, as well as a hinterland with the source of various contamination from human activities.These background is deeply involved in the barriers to the scientific elucidation of material dynamics and the solution of technical problems. In this study, we developed a material cycle analysis method using dissolved ions, rare earth elements, fluorescent dissolved organic substances, etc, which are information on intrinsic material origin of natural origin and anthropogenic origin in a typical watershed of cold snow. In addition, using these material origin information, we clarified that hydrological and hydraulic phenomena at snow melting / snow covering season supports the basic habitat environment such as aquatic organisms.
