EOF and spectral analysis were conducted to describe characteristic patterns of shoreline variation at multiple scales in time and space. A alongshore uniform shoreline migration toward offshore in summer and onshore in winter was dominant in the first EOF mode which secondarily exhibited a long-term trend of shoreline recession. The shoreline pattern reconstructed on a longer time scale represented a large scale shoreline undulation whose scale and migration speed were comparable to shoreline sand waves observed in various coasts. The shoreline pattern reconstructed on a shorter time scale represented alongshore uniform shoreline migration toward onshore and offshore in about five-year cycles, which corresponded to the average cycle of net offshore sandbar migration observed at the site.","subitem_description_type":"Abstract"},{"subitem_description":"細砂の遠浅な海岸に砂州が発達する海岸周辺の汀線の半年～20年程度の変動特性を解明するため，汀線測量データを解析し，様々な時空間スケールの変動成分の抽出を試みた．上位2モードから汀線の長期変化傾向と季節的変化を表す対照的な変動成分が捉えられた．周波数フィルタリングした上位4モードから得た5年周期の変動パターンは，砂州地形の周期的変動と連動した汀線移動が示唆された．砂州の影響による汀線の岸沖移動範囲は約4～8 mと推測され，夏季・冬季の汀線の前進・後退量の平均約7 mと同程度であった．冬季の汀線変化は最大波などの影響が大きいが，夏季は下位1/3の小さな波が平年より高くなると前進する傾向を示した．","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:15K06229, 研究期間(年度):2015-04-01 - 2018-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「河川・海岸域における流砂・漂砂系内の土砂動態と地形・底質変化に関する総合的理解」課題番号15K06229\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-15K06229/15K06229seika/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域地球社会基盤学系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052236","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=30313688"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=30313688","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-15K06229/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-15K06229/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-15K06229/15K06229seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-15K06229/15K06229seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-04-26"}],"displaytype":"detail","filename":"TE-PR-UMEDA-S-kaken 2018-6p.pdf","filesize":[{"value":"338.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-UMEDA-S-kaken 2018-6p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/45902/files/TE-PR-UMEDA-S-kaken 2018-6p.pdf"},"version_id":"0bf70fe2-40d0-41f7-86b0-0bc7b7aec8e6"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"河川・海岸域における流砂・漂砂系内の土砂動態と地形・底質変化に関する総合的理解","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"河川・海岸域における流砂・漂砂系内の土砂動態と地形・底質変化に関する総合的理解"},{"subitem_title":"Seasonal to decadal morphodynamics in an integrated watershed composed of a steep river and barred coasts","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2816"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-04-26"},"publish_date":"2019-04-26","publish_status":"0","recid":"45902","relation_version_is_last":true,"title":["河川・海岸域における流砂・漂砂系内の土砂動態と地形・底質変化に関する総合的理解"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T12:48:59.632144+00:00"}
