Hourly-averaged radar images were processed to observe longshore\ndistributions of shoreline positions. Variations of longshore mean shoreline positions\nand their fluctuation intensities observed in the years 2005 and 2006 showed a seasonal\nchange which followed the so-called beach-cycle. Longshore pixel intensities close to the\nwaterline were extracted from time-averaged images for every hour of the two years to\nprocess longshore time-stack image. Longshore migration speeds of shoreline mega-cusps\nwere estimated by cross correlation analysis of the time-stack image, and the reliability of\nthe method was checked. Migration speeds were compared to measured longshore current\nspeeds at the pier and the longshore component of the wave power, showing that they\nare highly synchronized for most conditions. Finally, the migration statistics were related\nto the wave data, and the results showed that the northwards migration rates were typically\nlarger than southwards rates, which was consistent with the statistical results for\nwave forcing variables. Also, the relationship between the migration speeds and the forcing\nvariables indicates that the migration was more active when the wave incidence angle was\nclose to 45◦.","subitem_description_type":"Abstract"}]},"item_5_identifier_34":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2241/100749"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"World Scientific"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1142/S0578563408001818","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© World Scientific Publishing Company and Japan Society of Civil Engineers"}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0578-5634","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11274987","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"GALAL, ELSAYED M."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKEWAKA, SATOSHI"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-12-19"}],"displaytype":"detail","filename":"CEJ_50-3.pdf","filesize":[{"value":"5.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"CEJ_50-3.pdf","url":"https://tsukuba.repo.nii.ac.jp/record/16886/files/CEJ_50-3.pdf"},"version_id":"13c6cac2-c35a-4e78-aebe-979c7e261267"}]},"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":"LONGSHORE MIGRATION OF SHORELINE MEGA-CUSPS OBSERVED WITH X-BAND RADAR","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"LONGSHORE MIGRATION OF SHORELINE MEGA-CUSPS OBSERVED WITH X-BAND RADAR"}]},"item_type_id":"5","owner":"1","path":["512","385"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-10-07"},"publish_date":"2008-10-07","publish_status":"0","recid":"16886","relation_version_is_last":true,"title":["LONGSHORE MIGRATION OF SHORELINE MEGA-CUSPS OBSERVED WITH X-BAND RADAR"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T10:03:43.223876+00:00"}
