In this study, the practical applicability of the pressure infiltrometer method which has been developed to measure K_<fs> of soil is examined using field and laboratory tests and numerical calculations. Sand was selected for the study. Theoretical features of the pressure infiltrometer method are explained by the field pemeability tests and the numerical calculations. It is shown that the pressure infiltrometer method can be an excellent practical in situ pemeability test. It is suggested that about 0.06cm-1 or some smaller value of α* may be more appropriate for sand and loam in calculating K_<fs> of soil. It is also found that the depth of the soil region whose pemeability is measured by the pressure infiltrometer method is changeable by selecting a suitable combination of the radius and insertion depth of the ring as well as the constant head imposed on the soil surface within the ring.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"164005","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Morii, Toshihiro"}]},{"nameIdentifiers":[{"nameIdentifier":"164006","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Akita, Yuki"}]},{"nameIdentifiers":[{"nameIdentifier":"164007","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sato, Miwa"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学農学部"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","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":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"森井, 俊広"}],"nameIdentifiers":[{"nameIdentifier":"164002","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"秋田, 由紀"}],"nameIdentifiers":[{"nameIdentifier":"164003","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐藤, みわ"}],"nameIdentifiers":[{"nameIdentifier":"164004","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":"2019-08-20"}],"displaytype":"detail","filename":"53_1_47-54.pdf","filesize":[{"value":"561.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"53_1_47-54.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28511/files/53_1_47-54.pdf"},"version_id":"c39f886a-4f01-419a-9913-52e523366fca"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"原位置透水試験","subitem_subject_scheme":"Other"},{"subitem_subject":"プレッシャーインフィルトロメータ法","subitem_subject_scheme":"Other"},{"subitem_subject":"ほ場試験","subitem_subject_scheme":"Other"},{"subitem_subject":"FEM数値計算","subitem_subject_scheme":"Other"},{"subitem_subject":"In-situ permeability test","subitem_subject_scheme":"Other"},{"subitem_subject":"Pressure infiltrometer method","subitem_subject_scheme":"Other"},{"subitem_subject":"Field test","subitem_subject_scheme":"Other"},{"subitem_subject":"FEM numerical calculation","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"土の飽和透水係数の原位置測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"土の飽和透水係数の原位置測定"},{"subitem_title":"土の飽和透水係数の原位置測定","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1616"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-02-13"},"publish_date":"2014-02-13","publish_status":"0","recid":"28511","relation_version_is_last":true,"title":["土の飽和透水係数の原位置測定"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:42.318029+00:00"}
