The dispersion term in the system is described by the integral with the kernel of the Fourier transform of dimensionless wave speed. The wave equation developed for spectral-wave components is applied to nonlinear waves on the step-type reef in two dimensions. Comparisons to verify the model are made between present numerical results with the finite element method and experimental data. Numerical simulation shows that there occur longer period waves rather than incident waves, because of nonlinear interaction between wave components and bathymetry of the reef. As a result, the wave amplification factor at the shoreline of the reef becomes greater than that of the linear wave theory. At the same time the peak position moves as if longer period waves were incident upon the reef.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学工学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/2217"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0389-102X"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN0025048X"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学工学部紀要"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueNumber":"52","bibliographicPageEnd":"39","bibliographicPageStart":"25"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"No52p25.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2002166/files/No52p25.pdf"},"version_id":"e3910592-ec9f-43c2-a055-467d60155c0b"}]},"item_title":"線形分散と浅海長波の非線形性を合わせ持つモデル方程式（第３報）－ステップ型リーフ上での波の非線形挙動－","item_type_id":"15","owner":"1","path":["1642837873116","1642838406845"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-10-28"},"publish_date":"2007-10-28","publish_status":"0","recid":"2002166","relation_version_is_last":true,"title":["線形分散と浅海長波の非線形性を合わせ持つモデル方程式（第３報）－ステップ型リーフ上での波の非線形挙動－"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-02-14T21:27:52.535384+00:00"}
