Z_1 is called the zero displacement or displacement height (by analogy to the concept of the displacement thickness in boundary layer theory). Zo is called the roughness parameter, roughness length, or simply roughness. When this formula is applied to the vertical velocity profiles in a river, a preliminary estimation of the value of those factors becomes necessary. In this paper, they are estimated from the observation data, and the advantage of using this formula is also shown.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長野工業高等専門学校"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00179170","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-1909","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_20":{"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":"松岡, 保正"}],"nameIdentifiers":[{"nameIdentifier":"1213","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":"2013-02-21"}],"displaytype":"detail","filename":"nagano_nct-18-15.pdf","filesize":[{"value":"323.1 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"nagano_nct-18-15.pdf","url":"https://nagano-nct.repo.nii.ac.jp/record/530/files/nagano_nct-18-15.pdf"},"version_id":"63605735-d826-43c6-9ca7-4e174aea8e98"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"礫床河川の粗度とゼロ面修正量","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"礫床河川の粗度とゼロ面修正量"}]},"item_type_id":"2","owner":"17","path":["42"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-02-21"},"publish_date":"2013-02-21","publish_status":"0","recid":"530","relation_version_is_last":true,"title":["礫床河川の粗度とゼロ面修正量"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-20T16:04:00.803735+00:00"}
