In this method these properties are assumed to be represented by van Genuchten\u0027s closed-form expressions. Unknown parameters of this model are identified by Genetic algorithms (GA) incorporating finite element analysis of transient axisymmetnc seepage flow. GA are search algorithms based on the mechanics of natural selection and natural genetics. They have become a popular global optimization method. A ponded singlering infiltrometer technique, such as the Guelph Pressure Infiltrometer is performed. Simultaneously the measured change of soil water content with time and cumulative inflow data are used to identify unsaturated soil hydraulic function parameters. The advantage of the proposed method is that it allows estimation of the unsaturated soil hydraulic parameters by quite simple in-situ permeability test data. The utility of our proposed method is demonstrated by using a numerical model and experimental data for Totton dune sand.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "41192", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Takeshita, Yuji"}]}, {"nameIdentifiers": [{"nameIdentifier": "41193", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Yagi, Kazuo"}]}, {"nameIdentifiers": [{"nameIdentifier": "41194", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Morii, Toshihiro"}]}, {"nameIdentifiers": [{"nameIdentifier": "41195", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Inoue, Mitsuhiro"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本地下水学会"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN10088275", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09134182", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "竹下, 祐二"}], "nameIdentifiers": [{"nameIdentifier": "41188", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "八木, 一雄"}], "nameIdentifiers": [{"nameIdentifier": "41189", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "森井, 俊広"}], "nameIdentifiers": [{"nameIdentifier": "41190", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "井上, 光弘"}], "nameIdentifiers": [{"nameIdentifier": "41191", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-30"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "44_1_21-33.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1200000.0, "url": {"label": "44_1_21-33.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3167/files/44_1_21-33.pdf"}, "version_id": "631f1a24-079e-45b0-81a2-8b8beb8e4a48"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "in situ permeability test", "subitem_subject_scheme": "Other"}, {"subitem_subject": "pressure infiltrometer", "subitem_subject_scheme": "Other"}, {"subitem_subject": "unsaturated hydraulic properties", "subitem_subject_scheme": "Other"}, {"subitem_subject": "genetic algorithms", "subitem_subject_scheme": "Other"}, {"subitem_subject": "parameter estimation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "inverse analysis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "sandy soil", "subitem_subject_scheme": "Other"}]}, "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": "原位置透水試験による砂質土地盤の不飽和浸透特性値の測定法", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "原位置透水試験による砂質土地盤の不飽和浸透特性値の測定法"}, {"subitem_title": "原位置透水試験による砂質土地盤の不飽和浸透特性値の測定法", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "487"], "permalink_uri": "http://hdl.handle.net/10191/25168", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-02-13"}, "publish_date": "2014-02-13", "publish_status": "0", "recid": "3167", "relation": {}, "relation_version_is_last": true, "title": ["原位置透水試験による砂質土地盤の不飽和浸透特性値の測定法"], "weko_shared_id": null}
