On previous studies using a hydraulic model experiment, we have expressed the\nice-jam-scale using the river ice velocity, width, thickness and length, and the river-width-reduction ratio\nand evaluate the attenuation ratio of the velocity of river ice with ice jam. However, no previous study has\ntaken into account the effects of branch river junction. In this study we carried out hydraulic experiments\nconsidering the effects of branch river junction and examined applicability of the ice-jam-scale. Furthermore,\nwe estimated the attenuation ratio of the velocity of river ice using the ice-jam-scale that we found\nby the two-dimensional non-uniform flow calculation and extracted the potential ice-jam locations with\nthe longitudinal variation of the cross-sectional profile.","subitem_description_type":"Abstract"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"89982","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Toyabe, Toshihito","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"89983","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yoshikawa, Yasuhiro","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"89984","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Okabe, Hirokazu","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"89985","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tanaka, Tadahiko","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":"鳥谷部, 寿人","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"吉川, 泰弘","creatorNameLang":"ja"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"岡部, 博一","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田中, 忠彦","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":"2018-04-20"}],"displaytype":"detail","filename":"2017-03 支川合流を考慮したアイスジャム発生に関する実験的研究.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2017-03 支川合流を考慮したアイスジャム発生に関する実験的研究","url":"https://kitami-it.repo.nii.ac.jp/record/8647/files/2017-03 支川合流を考慮したアイスジャム発生に関する実験的研究.pdf"},"version_id":"f44d665b-4ce1-4ad3-87b7-72a2c462fa35"}]},"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":"Hydraulic experiments","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Branch river junction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Attenuation ratio of the velocity of assembling ice pieces","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":"支川合流を考慮したアイスジャム発生に関する実験的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"支川合流を考慮したアイスジャム発生に関する実験的研究","subitem_title_language":"ja"},{"subitem_title":"HYDRAULIC MODEL EXPERIMENTS ON ICE JAM OCCURRENCE CONSIDERING THE EFFECTS OF BRANCH RIVER JUNCTION","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":"8647","relation_version_is_last":true,"title":["支川合流を考慮したアイスジャム発生に関する実験的研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-13T02:22:11.322868+00:00"}
