The CBS is a simple soil layer system which constitutes of a finer soil layer underlain by a coarser soil layer. Sand and gravel are usually employed to form the finer soil layer and the coarser soil layer, respectively. Downward percolation of water during infiltration or redistribution virtually ceases where the infiltrated water migrating through the sand layer encounters the gravel layer, and the water accumulates just above an interface between the soil layers with less percolating into the gravel layer lower. This accumulation of water continues until a moisture retention capacity of the sand is sufficiently large to force water to enter large pores of the gravel layer. In the paper, two applications of the CBS to solve a geotechnical problem relating to waste disposal and an agricultural problem relating to soil salinization are described and\\ntheir feasibility are discussed based on the fields experiments. In the first application, a shallow land waste repository, in which the CBS’s are included to reduce water infiltration and to divert percolating water through protected waste material, is proposed to isolate a hazardous waste material or a very low level radioactive waste. Observations of soil moisture content in the test land waste repository are discussed to show an effectiveness of the CBS. The second application of the CBS will contribute to development of an innovative irrigation technique in an agricultural land field. An effect of the water accumulating in the CBS on plant growth is examined in the field experiment. It is also shown that soil salinization caused by upward movement of saline water from groundwater is well prevented by the CBS. Both applications demonstrate that the CBS of soil may be well and successfully employed to attain sustainability in our geotechnical and agricultural fields.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"162434","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Morii, Toshihiro"}]},{"nameIdentifiers":[{"nameIdentifier":"162435","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Suzuki, Kazuyoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"162436","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Suzuki, Tetsuya"}]},{"nameIdentifiers":[{"nameIdentifier":"162437","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kawai, Takayuki"}]}]},"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":"162430","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 一兄"}],"nameIdentifiers":[{"nameIdentifier":"162431","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 哲也"}],"nameIdentifiers":[{"nameIdentifier":"162432","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"河合, 隆行"}],"nameIdentifiers":[{"nameIdentifier":"162433","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":"67(2)_125-132.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"67(2)_125-132.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28274/files/67(2)_125-132.pdf"},"version_id":"bd9a53b5-6cd6-4e52-b178-77db7a84fb5e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"土のキャピラリーバリア","subitem_subject_scheme":"Other"},{"subitem_subject":"盛土式廃棄物貯蔵施設","subitem_subject_scheme":"Other"},{"subitem_subject":"節水かんがい","subitem_subject_scheme":"Other"},{"subitem_subject":"塩分集積の抑制","subitem_subject_scheme":"Other"},{"subitem_subject":"土の不飽和水分特性","subitem_subject_scheme":"Other"},{"subitem_subject":"Capillary barrier of soil","subitem_subject_scheme":"Other"},{"subitem_subject":"Shallow land waste repository","subitem_subject_scheme":"Other"},{"subitem_subject":"Salinization prevention","subitem_subject_scheme":"Other"},{"subitem_subject":"Water saving irrigation","subitem_subject_scheme":"Other"},{"subitem_subject":"Unsaturated hydraulic properties of 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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"土のキャピラリーバリアの発現メカニズムと実務展開に向けた可能性調査試験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"土のキャピラリーバリアの発現メカニズムと実務展開に向けた可能性調査試験"},{"subitem_title":"土のキャピラリーバリアの発現メカニズムと実務展開に向けた可能性調査試験","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1587"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-04-20"},"publish_date":"2015-04-20","publish_status":"0","recid":"28274","relation_version_is_last":true,"title":["土のキャピラリーバリアの発現メカニズムと実務展開に向けた可能性調査試験"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:11.712173+00:00"}
