Outline of Final Research Achievements

Genetic-hierarchical landform classification systems were constructed based on landform development history of Kiso Range, Ou backbone Range, Chugoku Mountains, Shirasu Plateau, Kanto and Nobi Plain, Sanriku coast, Japan focusing on landform changes/formation such as landslides, slope failures, multiple rides, dissection valleys, debris-flow fans, river avulsion, crevasse spray, estuary-delta systems, liquefactions, and tsunamis, all of which have potential to produce natural disasters. Geomorphic conditions suitable to generate diverse and sudden landform changes above were discussed by geo-systematic analysis including GNSS, UAV-Sfm photogrammetry, machine learning, geologic core analysis, and dating of radiometric, cosmogenic, OSL, tephrochronological　methods.
