Firstly, we investigated the interaction between widening of gravel channel and degradation of channel bed with hydraulic model experiment. As a result, it was understood that the conventional diffusion model of the degradation with a modified diffusion coefficient could be applied even if the channel widening accompanies. Secondary, we constructed the 2-D numerical simulation model taking account of the widening process with bank erosion in a gravel channel, and examined the application of the numerical model by using the experimental data. The numerical analysis could explain the flume experiments well.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/8643"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会","subitem_publisher_language":"ja"}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"土木編集第07010号","subitem_rights_language":"ja"}]},"item_10_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_10_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-7806","subitem_source_identifier_type":"PISSN"}]},"item_10_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_1615787544753":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"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":"後藤, 孝臣","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18688","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"GOTO, Takaomi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18689","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北村, 忠紀","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18690","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KITAMURA, Tadanori","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18691","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻本, 哲郎","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18692","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TSUJIMOTO, Tetsuro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18693","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":"2018-02-19"}],"displaytype":"detail","filename":"v684_p35-46.pdf","filesize":[{"value":"816.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"v684_p35-46.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/6976/files/v684_p35-46.pdf"},"version_id":"8b366cbd-96ff-498a-bfc4-f6cb3ef40bf6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"bank erosion","subitem_subject_scheme":"Other"},{"subitem_subject":"degradation","subitem_subject_scheme":"Other"},{"subitem_subject":"bedload transport","subitem_subject_scheme":"Other"},{"subitem_subject":"movable-bed model test","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":"上・下流境界条件の変化による直線砂礫流路の側岸侵食を伴う河床低下に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"上・下流境界条件の変化による直線砂礫流路の側岸侵食を伴う河床低下に関する研究","subitem_title_language":"ja"}]},"item_type_id":"10","owner":"1","path":["322"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-08-08"},"publish_date":"2007-08-08","publish_status":"0","recid":"6976","relation_version_is_last":true,"title":["上・下流境界条件の変化による直線砂礫流路の側岸侵食を伴う河床低下に関する研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T03:52:19.903984+00:00"}
