The geomorphic thresholds for the debris-flow arrival become smaller with an increase in rainfall amount in granite areas, which increases the debris-flow risk in many basins. The geomorphic thresholds are shown to vary significantly with lithology. The threshold decreases in a slope area with the coarser soil and the soil-layer structure that soil water is restricted to moving deeper into the soil below the potential slip plane. The arrival ratio of debris flow to the basin outlet becomes larger with an increase in the drainage area.\u003c/p\u003e", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "公益社団法人 日本地すべり学会", "subitem_publisher_language": "ja"}, {"subitem_publisher": "The Japan Landslide Society", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.3313/jls.54.91"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1348-3986", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "若月強", "creatorNameLang": "ja"}, {"creatorName": "若月強", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "佐藤昌人", "creatorNameLang": "ja"}, {"creatorName": "佐藤昌人", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "菊池輝海", "creatorNameLang": "ja"}, {"creatorName": "菊池輝海", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "石川美樹", "creatorNameLang": "ja"}, {"creatorName": "石川美樹", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "山岸千鶴", "creatorNameLang": "ja"}, {"creatorName": "山岸千鶴", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "山下久美子", "creatorNameLang": "ja"}, {"creatorName": "山下久美子", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_title": "土砂移動分布図を利用した土石流到達流域の推定-降雨を考慮した地形的閾値について-", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "土砂移動分布図を利用した土石流到達流域の推定-降雨を考慮した地形的閾値について-", "subitem_title_language": "ja"}, {"subitem_title": "Debris-flow prone basins estimated using distribution maps of slope movements-Geomorphic thresholds considering rainfall characteristics-", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/3835", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-04-27"}, "publish_date": "2023-04-27", "publish_status": "0", "recid": "3835", "relation": {}, "relation_version_is_last": true, "title": ["土砂移動分布図を利用した土石流到達流域の推定-降雨を考慮した地形的閾値について-"], "weko_shared_id": -1}
