It is important to collect examples of recent ice jams and to solve the problems by applying the model on actual rivers for practical use. At first we investigated the mechanism of ice jam which occurred in several rivers in Hokkaido in March 2020. Time of outbreak and disappearance of ice jam was obtained successfully with video image by river surveillance camera and telemeting water level. Next we tried to evaluate the occurance risk evaluation of this ice jam. We compared with factor which influenced ice jam occurance in 2018 and in 2020. We also examined problems and improvement about outbreak prediction with the river ice thickness prediction model.","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_208":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"40022430460","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":"EISSN"}]},"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":"横山, 洋","creatorNameLang":"ja"},{"creatorName":"YOKOYAMA, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"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":[{},{}]},{"creatorNames":[{"creatorName":"伊波, 友生","creatorNameLang":"ja"},{"creatorName":"INAMI, Yu","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"矢部, 浩規","creatorNameLang":"ja"},{"creatorName":"YABE, Hiroki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2021-05-26"}],"displaytype":"detail","filename":"dobokuB1_Vol.76,No.2,I_157-I_162,2020.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"土木学会論文集B1(水工学) Vol.76, No.2, I_157-I_162, 2020","objectType":"fulltext","url":"https://kitami-it.repo.nii.ac.jp/record/2000053/files/dobokuB1_Vol.76,No.2,I_157-I_162,2020.pdf"},"version_id":"726fffee-aa11-445a-b291-bd3e8cac7d17"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ice jam prediction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"field survey","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"river monitoring camera","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"water level fluctuation","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":"2020年3月に発生したアイスジャムの現地調査および発生リスクの評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2020年3月に発生したアイスジャムの現地調査および発生リスクの評価","subitem_title_language":"ja"},{"subitem_title":"FIELD SURVEY OF ICE JAM IN MARCH 2020 AND EVALUATION OF ICE JAM OCCURANCE RISK","subitem_title_language":"en"}]},"item_type_id":"3","owner":"15","path":["86"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-05-26"},"publish_date":"2021-05-26","publish_status":"0","recid":"2000053","relation_version_is_last":true,"title":["2020年3月に発生したアイスジャムの現地調査および発生リスクの評価"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2022-12-13T02:24:21.837461+00:00"}
