A new model (a coupled Finite Difference-Ramdom Walk Melhod : FD-RWM) of DNAPL migration for an aqueous phase and for a nonaqueous mobile/immobile phase with entrapment effect: of DNAPL blobs in pores is presented. It has been developed m a canbinatim of the RWM with the FUM of the advectim dispersim equatim disdretized using Semi-hnplicit TVD (Total Variatim Diminishing) scheme. Investigating field scale applicability of the model with experimental results and observed data at a site, it demonstrates that the FD-RWM can provide information of a total amount of the infiltrated and remained DNAPL mass in the aquifer.","subitem_description_type":"Abstract"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_other_language_22":{"attribute_name":"その他の言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人土木学会"}]},"item_119_relation_16":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.2208/jscej.2005.782_11","subitem_relation_type_select":"DOI"}}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02897806","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"SASAKI, Takashi"},{"subitem_text_value":"SATO, Kuniaki"},{"subitem_text_value":"WADA, Akira"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002618"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"埼玉大学地圏科学研究センター"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"Geosphere Research Institute, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2005"}]},"item_119_version_type_28":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐々木, 孝"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤, 邦明"},{"creatorName":"サトウ, クニアキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"和田, 明"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1002618.pdf","filesize":[{"value":"3.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002618.pdf","url":"https://sucra.repo.nii.ac.jp/record/14350/files/A1002618.pdf"},"version_id":"6651e5ac-283a-42e4-8c42-7af3eb44f399"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"DNAPL(Dense Non-Aqueous Phase liquid)","subitem_subject_scheme":"Other"},{"subitem_subject":"random-walk-method","subitem_subject_scheme":"Other"},{"subitem_subject":"pheriatic aquifer","subitem_subject_scheme":"Other"},{"subitem_subject":"entrapped effect","subitem_subject_scheme":"Other"},{"subitem_subject":"TVD(Total Variation Diminishing) scheme","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"差分連成ランダムウォーク法による不圧帯水層のDNAPL移行解析と現地適用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"差分連成ランダムウォーク法による不圧帯水層のDNAPL移行解析と現地適用"}]},"item_type_id":"119","owner":"3","path":["242"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-21"},"publish_date":"2008-04-21","publish_status":"0","recid":"14350","relation_version_is_last":true,"title":["差分連成ランダムウォーク法による不圧帯水層のDNAPL移行解析と現地適用"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:01:54.545545+00:00"}
