The mechanism of the oscillation is still not clearly understood because of the complexity of the phenomena. In this research, by using a stereoscopic surface measurement system developed by the authors, time-dependent water surface configurations are successfully measured at a sampling rate of 12 Hz, from which general features of the surface oscillation are made clear for a wide range of Froude numbers. Then, we applied the proper orthogonal decomposition (POD) method to measure results. We found that the surface oscillation can be clearly decomposed into a seiche-like major mode and sub-modes with smaller wavelengths.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"土木学会水理委員会"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0912-2508","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA1045915X","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"41"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2006","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicPageEnd":"51","bibliographicPageStart":"41","bibliographicVolumeNumber":"24","bibliographic_titles":[{"bibliographic_title":"Journal of hydroscience and hydraulic engineering"},{"bibliographic_title":"Journal of hydroscience and hydraulic engineering"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jsce.or.jp/publication/e/book/book_jhhe.html#242","subitem_relation_type_select":"URI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"JHHE_24_41.pdf","filesize":[{"value":"3.6 MB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2007390/files/JHHE_24_41.pdf"},"version_id":"e68eff7a-4222-4126-92ce-170447713d9d"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"34910"},"item_title":"Surface oscillations in flow past a side cavity using stereoscopic measurement and POD","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2007390","relation_version_is_last":true,"title":["Surface oscillations in flow past a side cavity using stereoscopic measurement and POD"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-21T09:50:17.529125+00:00"}
