| Outline of Final Research Achievements |
In order to elucidate the influence of climate change and forest management on the water volume and water quality control function of the catchment, we considered how the water flow within the catchments in mountainous region. It was clarified that the roles of bedrock were important; how the groundwater infiltrated into the bedrock, how much volume of groundwater was stored, and how flowed out from there with the expansion of the catchment scale in each catchment. Particularly in the granite catchment, the bedrock seepage from the weathered bedrock matrix was quantitatively important to contribute the stream flow, as well as the bedrock spring through the fissure.
