To evaluate hydrodynamics forces, velocity fields on the beach are measured in laboratory experiments using cantilever-type velocimeter. In the experiments, deformations and grading process of material of different sizes are investigated. Critical conditions for several types of sediment movements are derived assuming static state. Then these conditions are compared with acting wave forces evaluated by the Morison equation and mechanism of sediment movement is discussed, Through the investigations, infiltration flow during rundown process is found to cause asymmetric exerting force on bed material. Comparisons between wave force and stability condition give good explanation for dominant direction of sediment movement and resultant beach profile. Moreover, the present results are found to be consistent to the beach profile observed at real gravel beaches.","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/2237/8607"}]},"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":"馬, 賢鎬","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18481","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MA, Hyun-Ho","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18482","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"水谷, 法美","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18483","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MIZUTANI, Norimi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18484","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"江口, 周","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18485","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"EGUCHI, Shu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18486","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":"v789_p73-82.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"v789_p73-82.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/6939/files/v789_p73-82.pdf"},"version_id":"898383fa-1fa0-4f64-b94c-4ee2e54e2882"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"beach profile","subitem_subject_scheme":"Other"},{"subitem_subject":"grading process","subitem_subject_scheme":"Other"},{"subitem_subject":"gravel beach","subitem_subject_scheme":"Other"},{"subitem_subject":"Morison equation","subitem_subject_scheme":"Other"},{"subitem_subject":"infiltration","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":"礫浜斜面上の流速場と漂砂移動機構に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"礫浜斜面上の流速場と漂砂移動機構に関する研究","subitem_title_language":"ja"}]},"item_type_id":"10","owner":"1","path":["322"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-07-31"},"publish_date":"2007-07-31","publish_status":"0","recid":"6939","relation_version_is_last":true,"title":["礫浜斜面上の流速場と漂砂移動機構に関する研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T03:52:19.522019+00:00"}
