This paper presents a new computational approach for shallow water flows with the emphasis on the accurate modeling of complex geometries in the Cartesian coordinate system. Expanding the concept of CIP-CSL2 scheme, the present method simultaneously solves point, line and area averaged values of a computational cell to directly capture the effects of complex boundary shapes and conditions. The method is then tested against the one-dimensional dam-break problem to find good agreement with theoretical results. Further, the applicability of the method is demonstrated for two flows. In one case, hydraulic bores bounce from impermeable walls and in the other case water flows between narrow impermeable walls whose direction is arbitrary, both of which are known to be tough problems.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"土木学会"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0916-7374","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN10426673","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"799"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2006-02","bibliographicIssueDateType":"Issued"},"bibliographicPageEnd":"804","bibliographicPageStart":"799","bibliographicVolumeNumber":"50","bibliographic_titles":[{"bibliographic_title":"水工学論文集"},{"bibliographic_title":"水工学論文集"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_b1a7d7d4d402bcce","subitem_version_type":"AO"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"suikogaku_50_799.pdf","filesize":[{"value":"883.6 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2010251/files/suikogaku_50_799.pdf"},"version_id":"3d9d2e74-86e4-42d0-a214-038b330a81ff"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"16609"},"item_title":"任意の境界形状を有する二次元浅水流の高精度解析手法の開発","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2010251","relation_version_is_last":true,"title":["任意の境界形状を有する二次元浅水流の高精度解析手法の開発"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-22T07:23:46.266110+00:00"}
