In Hokkaido located in the northernpart of Japan, ROS events also has been recorded in various places in the past and has been conserned to be increased in future due to the rise of temperatures over snowy-cold region. In this study, authors conduted flume experiments to understand the effects of rainfall on snow melt and snowmelt runoff, which affects ROS disasters during winter. The results showed that in the cases, estimated maximum temperature in winter (snow melting season), snow avalanches occurred due to the rainfall. In contrast, where the temperature is below 10 ℃, the rainfall slowly penetrate and formed the flow path at the bottom of snow layer, leading into an increase of 1.23 times of the runff discharge to the low channel path.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会","subitem_publisher_language":"ja"}]},"item_3_relation_191":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.2208/jscejhe.75.2_I_925","subitem_relation_type_select":"DOI"}}]},"item_3_relation_208":{"attribute_name":"論文ID(NAID)","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"130007940176","subitem_relation_type_select":"NAID"}}]},"item_3_select_195":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_3_source_id_187":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2185-467X","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"守田, 銀二","creatorNameLang":"ja"},{"creatorName":"MORITA, Ginji","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"今, 日出人","creatorNameLang":"ja"},{"creatorName":"KON, Hideto","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"久加, 朋子","creatorNameLang":"ja"},{"creatorName":"KYUKA, Tomoko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"9000410757218","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000410757218"}]},{"creatorNames":[{"creatorName":"清水, 康行","creatorNameLang":"ja"},{"creatorName":"SHIMIZU, Yasuyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"40132","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000254955803","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000254955803"}]},{"creatorNames":[{"creatorName":"吉川, 泰弘","creatorNameLang":"ja"},{"creatorName":"ヨシカワ, ヤスヒロ","creatorNameLang":"ja-Kana"},{"creatorName":"YOSHIKAWA, Yasuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"89971","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"50414149","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=50414149"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2021-05-25"}],"displaytype":"detail","filename":"土木学会論文集B1(水工学) Vol.75, No.2, I_925-I_930, 2019.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://kitami-it.repo.nii.ac.jp/record/2000048/files/土木学会論文集B1(水工学) Vol.75, No.2, I_925-I_930, 2019.pdf"},"version_id":"82eb1d10-0780-45d3-b624-bfc8c9aa9570"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"rain-on-snow flood","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flume experiment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"snowmelt runoff","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"snow avalanches","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"積雪寒冷地における降雨を伴う積雪層の融雪特性に関する実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"積雪寒冷地における降雨を伴う積雪層の融雪特性に関する実験","subitem_title_language":"ja"},{"subitem_title":"EXPERIMENTAL STUDY ON RAIN-ON-SNOW EVENTS IN SNOWY-COLD REGION","subitem_title_language":"en"}]},"item_type_id":"3","owner":"15","path":["86"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-05-25"},"publish_date":"2021-05-25","publish_status":"0","recid":"2000048","relation_version_is_last":true,"title":["積雪寒冷地における降雨を伴う積雪層の融雪特性に関する実験"],"weko_creator_id":"15","weko_shared_id":3},"updated":"2024-10-18T06:00:00.372658+00:00"}
