| Outline of Final Research Achievements |
We evaluated residence time and storage volume of subsurface water in headwaters of mountainous catchments, central area of Japan. The estimated resdience time of subsurface water ranges from 10 years to 60 years, and the storage voulme rages from 10,000 to 10,000,000 cubic meter. The subsurface water storage in paleozoic watersheds tends to be higher than that of granite watersheds, and the residence time and storage range much in the granite watersheds, because the hydrological response is sensitive in the granite watersheds.
