A river ice calculation model was developed to determine the dynamics of frazil slush\ngeneration, transport, and accumulation. Field observations of frazil slush transport, ice sheet and frazil slush cross sections were performed. In the results, The phenomenon in which a river freezes begins from\nintake facilities, and it progresses to upstream direction. Frazil slush that is generated upstream accumulates under downstream ice sheets. Frazil slush accumulates more quickly in upstream than downstream. Then, as\nupstream frazil slush accumulation begins to flow downstream, it accumulates more quickly in downstream.","subitem_description_type":"Abstract"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"89975","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yoshikawa, Yasuhiro","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"89976","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Okabe, Hirokazu","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"89977","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hashiba, Masahiro","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"89978","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Morita, Tomotsugu","nameLang":"en"}]}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会"}]},"item_3_rights_192":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2017 土木学会"}]},"item_3_select_195":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"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":"吉川, 泰弘","creatorNameLang":"ja"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"岡部, 博一","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"橋場, 雅弘","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森田, 共胤","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-04-23"}],"displaytype":"detail","filename":"2017-03 寒冷地河川における取水堰上流の晶氷変動現象に関する研究.pdf","filesize":[{"value":"778.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"寒冷地河川における 取水堰上流の晶氷変動現象に関する研究","url":"https://kitami-it.repo.nii.ac.jp/record/8646/files/2017-03 寒冷地河川における取水堰上流の晶氷変動現象に関する研究.pdf"},"version_id":"df15c575-6309-4c05-9d7f-cd31eb104472"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ice-covered river","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Frazil slush","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Calculation model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Field observation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Water Intake facilities","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":"寒冷地河川における 取水堰上流の晶氷変動現象に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"寒冷地河川における 取水堰上流の晶氷変動現象に関する研究","subitem_title_language":"ja"},{"subitem_title":"FRAZIL SLUSH VARIATION IN TAKE FACILITIES ON ICE-COVERED RIVERS","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["86"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2018-04-23"},"publish_date":"2018-04-23","publish_status":"0","recid":"8646","relation_version_is_last":true,"title":["寒冷地河川における 取水堰上流の晶氷変動現象に関する研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-13T02:22:11.990237+00:00"}
