Research Abstract

Since 1989, we have carried out the observations on hydro-geomorphology to make clear the controlling factors of water cycle in the mountain regions with small reliefs. As for the experimental watershed in cases of granitic mountain region, we chose the Akatsu watershed in the Aichi Tokyo University Forests and Obara watershed in Obara Village. To compare with those watershed to another geologic area, we settled the Inuyama watershed in the Aichi Tokyo University Forests, which is covered by sand and gravel of fluvial fan deposit.
In this year, we focused on the surface layer including, litter as concentrated flow path of storm flow. To make clear the role of such layer to the stream flow generation, observations in the Akatsu and Inuyama experimental watershed and laboratory experiments on those characteristics of hydraulic conductivity and water retention were carried out.
From laboratory experiments, it was clear that saturated subsurface flow occurred through the litter layer overlying weathered soil. Although we could not observe subsurface water flows in both layers of litter and surface weathered soil distinctively, it was confirmed that saturated throughflow in the surface soil layer occurred during the storm event.
