Outline of Final Research Achievements

This research investigated the factors affecting the long-term structural integrity of river levees, focusing on the mechanical, hydraulic and physical processes at levee-atmosphere or levee-subsoil interfaces. The work involved long-term field monitoring of hydraulic states in levees at multiple sites, and modelling of various processes such as evapotranspiration, snow accumulation and melting, air-water coupled flow, etc. By implementing these models into seepage flow analysis, an integrated methodology to assess long-term integrity of levees with various soil types and under various climates is developed.

Academic Significance and Societal Importance of the Research Achievements

国内に1万km以上の延長をもつ河川堤防の構造安定性の評価には、その土質や気候の特性に関わらず、全国で一律の解析手法が適用されている。しかし、洪水時はもとより、洪水時挙動と深いつながりのある非洪水時状態を気候・季節に応じて予測再現するには、植生による蒸発散や、積雪・融雪の有無など、多くの地表面過程の影響を考慮する必要があり、現行規定ではこれらの因子を考慮していない。本研究は、これらの因子の重要度を長期原位置観測により解明し、予測解析に取り入れる手法を提案することで、重要な社会基盤たる河川堤防の品質管理に貢献する多くの知見を得た。
