The head loss property of the flow is expressed by the Forchheimer equation in which two coefficients are included. The simple genetic algorithm searches a chromosome that minimizes a squared deviation of flow discharge through rockfill between observation and FEM calculation, and then determines an optimal set of coefficients. Two coefficients of non-Darcy flow are coded into a binary chromosome. The fitness value of the chromosome is calculated as a reciprocal of a sum of the squared deviation of flow discharge mentioned above. The chromosomes with large fitness are selected to reproduce a next generation of offsprings. The parameter estimation procedure is applied to stage-discharge data measured in laboratory embankment tests in a water flume to estimate two coefficients of non-Darcy flow. Good comparison between measurement and FEM calculation shows a practical effectiveness of the parameter estimation procedure developed.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "163979", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Morii, Toshihiro"}]}]}, "item_7_publisher_7": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u65b0\u6f5f\u5927\u5b66\u8fb2\u5b66\u90e8"}]}, "item_7_select_19": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00183393", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03858634", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u68ee\u4e95, \u4fca\u5e83"}], "nameIdentifiers": [{"nameIdentifier": "163978", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KK_54(2)_159-167.pdf", "filesize": [{"value": "685.0 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 685000.0, "url": {"label": "KK_54(2)_159-167.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/28507/files/KK_54(2)_159-167.pdf"}, "version_id": "613d192f-5f16-49d9-9a3a-64ce2f2adef9"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "\u30ed\u30c3\u30af\u30d5\u30a3\u30eb", "subitem_subject_scheme": "Other"}, {"subitem_subject": "\u975e\u30c0\u30eb\u30b7\u30fc\u6d41\u308c", "subitem_subject_scheme": "Other"}, {"subitem_subject": "\u30d1\u30e9\u30e1\u30fc\u30bf\u63a8\u5b9a", "subitem_subject_scheme": "Other"}, {"subitem_subject": "\u5358\u7d14\u907a\u4f1d\u7684\u30a2\u30eb\u30b4\u30ea\u30ba\u30e0", "subitem_subject_scheme": "Other"}, {"subitem_subject": "FEM\u8a08\u7b97", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Rockfill", "subitem_subject_scheme": "Other"}, {"subitem_subject": "non-Darcy flow", "subitem_subject_scheme": "Other"}, {"subitem_subject": "parameter estimation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "simple genetic algorithm", "subitem_subject_scheme": "Other"}, {"subitem_subject": "FEM calculation", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "\u907a\u4f1d\u7684\u30a2\u30eb\u30b4\u30ea\u30ba\u30e0\u3092\u7528\u3044\u305f\u975e\u30c0\u30eb\u30b7\u30fc\u6d41\u308c\u306e\u30d1\u30e9\u30e1\u30fc\u30bf\u63a8\u5b9a", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u907a\u4f1d\u7684\u30a2\u30eb\u30b4\u30ea\u30ba\u30e0\u3092\u7528\u3044\u305f\u975e\u30c0\u30eb\u30b7\u30fc\u6d41\u308c\u306e\u30d1\u30e9\u30e1\u30fc\u30bf\u63a8\u5b9a"}, {"subitem_title": "\u907a\u4f1d\u7684\u30a2\u30eb\u30b4\u30ea\u30ba\u30e0\u3092\u7528\u3044\u305f\u975e\u30c0\u30eb\u30b7\u30fc\u6d41\u308c\u306e\u30d1\u30e9\u30e1\u30fc\u30bf\u63a8\u5b9a", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["453/456", "485/872/1583/1613"], "permalink_uri": "http://hdl.handle.net/10191/17325", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2012-01-31"}, "publish_date": "2012-01-31", "publish_status": "0", "recid": "28507", "relation": {}, "relation_version_is_last": true, "title": ["\u907a\u4f1d\u7684\u30a2\u30eb\u30b4\u30ea\u30ba\u30e0\u3092\u7528\u3044\u305f\u975e\u30c0\u30eb\u30b7\u30fc\u6d41\u308c\u306e\u30d1\u30e9\u30e1\u30fc\u30bf\u63a8\u5b9a"], "weko_shared_id": null}
