We conducted an ice jam experiment. The section of this experiment waterway is compound cross-section. Polypropylene and actual ice were used for the ice model in this experiment. The study clarified the following. (1) By ice jams, the speed of the ice model decreases and the number increases. (2) The ice model was detoured at bridge piers and flowed on the high-water channel. And it was flowing into the low-water channel in the downstream. (3) After ice jam occurrence, Flooding begins from the upstream site. Later, Flooding flowed to the downstream site. (4) The flooding speed is fast when discharge is large. As time passes, the flooding area becomes the constant value. (5) In the ice jams site, the upstream water level went up, the downstream water level descended. The downstream water level has been increased suddenly after ice jams breaking.","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_1411","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":"130007940143","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":"小池, 太郎","creatorNameLang":"ja"},{"creatorName":"KOIKE, Taro","creatorNameLang":"en"}]},{"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"}],"familyNames":[{"familyName":"吉川","familyNameLang":"ja"},{"familyName":"ヨシカワ","familyNameLang":"ja-Kana"},{"familyName":"YOSHIKAWA","familyNameLang":"en"}],"givenNames":[{"givenName":"泰弘","givenNameLang":"ja"},{"givenName":"ヤスヒロ","givenNameLang":"ja-Kana"},{"givenName":"Yasuhiro","givenNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"横山, 洋","creatorNameLang":"ja"},{"creatorName":"YOKOYAMA, Hiroshi","creatorNameLang":"en"}],"familyNames":[{"familyName":"横山","familyNameLang":"ja"},{"familyName":"YOKOYAMA","familyNameLang":"en"}],"givenNames":[{"givenName":"洋","givenNameLang":"ja"},{"givenName":"Hiroshi","givenNameLang":"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":"2021-05-25"}],"displaytype":"detail","filename":"土木学会論文集B1(水工学) Vol.75, No.2, I_1411-I_1416, 2019..pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://kitami-it.repo.nii.ac.jp/record/2000046/files/土木学会論文集B1(水工学) Vol.75, No.2, I_1411-I_1416, 2019..pdf"},"version_id":"92a8f238-216c-4f15-9870-62b33c7e41e4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ice jam","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"experiment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"bridge piers","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"water level variation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"real ice","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":"橋脚部における実氷を用いたアイスジャム氾濫実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"橋脚部における実氷を用いたアイスジャム氾濫実験","subitem_title_language":"ja"},{"subitem_title":"ICE JAM FLOOD EXPERIMENT USING REAL ICE AROUND BRIDGE PIERS","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":"2000046","relation_version_is_last":true,"title":["橋脚部における実氷を用いたアイスジャム氾濫実験"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2022-12-13T02:24:48.028278+00:00"}
