Abstract: 著者らは物理機構に基づく土砂生産のモデルを開発し,精度の高い土砂生産量の短期・長期予測および流域全体のモニタリングを可能にしようとしているが,最終的にはこれを土砂生産マップに組み込み,土砂生産量の予測情報,モニタリング情報を提供できるようにしたい。モデルの開発に当たっては,土砂生産特性を十分考慮することが重要であり,本研究では高原川流域を対象にしてそれを検討する。その結果,土砂生産量は斜面の凍結融解と密接な関係にあることがわかった。
We are developing a sediment production map informative for the integrated sediment management. The map based on a sediment production model can be used for predicting and monitoring the sediment production over a watershed. To make the map much more effective, the process of sediment production should be fully introduced into the modeling. In this paper, we have described the characteristics on sediment production based on a long-term observation data in the Takahara river basin. The data have shown the sediment production is dependent on the rainfall events, but the volume is dependent on the freezing and thawing process on the weathered slope. The sediment production processes over a year was described on the basis of observation data.
