Research Abstract |
To assess the impact of land-use change in Satoyama catchment on sediment delivery, I investigated the land-use history based on aerial photography. Additionally, using sediment core sample retrieved from small reservoir, I tried to estimate the long-term erosion history in the catchment based on dating technique for sediment. Sedimentation rate was significantly decreased when the dominant plant species was converted from deciduous broad-leaved forest to conifer plantation.
