They also migrate in weakly meandering channels, but do not move downstream through more strongly meander channels. We experimentally studied the critical bend angles to suppress bar migrations using various kinds of sine-generated meander channels. The critical bend angles are smaller as wavelengths of meander channels are longer. The relations between the critical bend angles and wavelengths of meander channels are nearly identical even in three different hydraulic conditions under which meander wavelengths are from six to twelve times as long as the channel width. These results are almost equal to those obtained in the previous study by Kinoshita and Miwa in their zigzag meander channels. In meander channels with much longer wavelengths, alternate bars migrate easily as mobile short bars develop in the channels. Therefore, the critical bend angles become larger.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"72384","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MIWA, Hajime"}]},{"nameIdentifiers":[{"nameIdentifier":"72385","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NAGAYOSHI, Takeshi"}]}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本自然災害学会"}]},"item_16_relation_16":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002941699/","subitem_relation_type_select":"URI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本自然災害学会"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-6021","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学農学部"},{"subitem_text_value":"岩手大学大学院連合農学研究科, （現）秋田県立大学生物資源科学部"}]},"item_16_version_type_27":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"三輪, 弌"}],"nameIdentifiers":[{"nameIdentifier":"72382","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"永吉, 武志"}],"nameIdentifiers":[{"nameIdentifier":"72383","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"jjsnds-v17n4p361-370.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jjsnds-v17n4p361-370.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9236/files/jjsnds-v17n4p361-370.pdf"},"version_id":"d2c34451-52c2-495a-9abe-72cf7461291f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"交互砂洲","subitem_subject_scheme":"Other"},{"subitem_subject":"砂洲移動","subitem_subject_scheme":"Other"},{"subitem_subject":"蛇行水路","subitem_subject_scheme":"Other"},{"subitem_subject":"水利実験","subitem_subject_scheme":"Other"},{"subitem_subject":"限界蛇行角","subitem_subject_scheme":"Other"},{"subitem_subject":"alternate bar","subitem_subject_scheme":"Other"},{"subitem_subject":"bar migration","subitem_subject_scheme":"Other"},{"subitem_subject":"meander channel","subitem_subject_scheme":"Other"},{"subitem_subject":"hydraulic experiment","subitem_subject_scheme":"Other"},{"subitem_subject":"critical bend angle","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":"実験蛇行水路における交互砂洲の移動抑止限界","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"実験蛇行水路における交互砂洲の移動抑止限界"}]},"item_type_id":"16","owner":"3","path":["1510"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-30"},"publish_date":"2010-11-30","publish_status":"0","recid":"9236","relation_version_is_last":true,"title":["実験蛇行水路における交互砂洲の移動抑止限界"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:09:42.941091+00:00"}
