Outline of Final Research Achievements |
In situ structures of mountain watershed in terms of spatial variations of permeability, which might significantly control groundwater dynamics within soil and deep bedrock layers, were observed with unprecedented detail by applying new subsurface investigation and topographical survey techniques coupled with intensive hydrometric observations for some mountain watersheds. This study imply existences of multi system of groundwater aquifer in the bedrock caused by geological structures within even the watershed smaller than about 1 ha, and indicated that those hydro-geological structure with highly spatial variation could significantly affect occurrence of landslides and time lags of landslides induced by rainfall.
