Autor: Saleh Yousefi, Sayed Naeim Emami, Mohammad Nekoeimehr, Omid Rahmati, Fumitoshi Imaizumi, Christopher Gomez, Aleksandar Valjarevic
Publikováno v: Land, Vol 13, Iss 10, p 1583 (2024)
Forest roads have been recognized as one of the significant contributors to soil erosion processes in forested areas. The construction and maintenance of forest roads can cause severe environmental impacts, including soil erosion, sedimentation, and

Spatial accuracy assessment of unmanned aerial vehicle-based structures from motion multi-view stereo photogrammetry for geomorphic observations in initiation zones of debris flows, Ohya landslide, Japan
Autor: Haruka Tsunetaka, Norifumi Hotta, Yuichi S. Hayakawa, Fumitoshi Imaizumi
Publikováno v: Progress in Earth and Planetary Science, Vol 7, Iss 1, Pp 1-14 (2020)
Abstract Fluctuations in sediment storage arising from sediment discharge and recharge in headwater channels are an important factor influencing changes in landforms in mountainous areas, but the frequency of surveys is limited because of access diff

Morphological characteristics and conditions of drainage basins contributing to the formation of debris flow fans: examination of regions with different rock strength using decision tree analysis
Autor: Ken'ichi Koshimizu, Satoshi Ishimaru, Fumitoshi Imaizumi, Gentaro Kawakami
Debris flows cause severe disasters, such as human damage and the collapse of houses. Establishment of the early warning systems in the basins with high debris flow risks is needed to reduce debris flow disasters. Because debris flows often form debr

Effects of terrain on the occurrence of debris flows after forest harvesting
Autor: Fumitoshi Imaizumi, Roy C. Sidle
Publikováno v: Geografiska Annaler: Series A, Physical Geography. 103(3):259-272
Forest harvesting and subsequent forest regeneration represent widespread changes in land cover in mountain regions. Although impacts of forest harvesting on landslide initiation has been widely re...
