The CB 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 soil water during infiltration or redistribution virtually ceases where the 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 CB system to solve a geo-environmental or geotechnical problem relating to waste disposal and an agricultural problem relating to water harvesting are described and their feasibility are discussed based on the fields experiments. In the first application, a shallow land waste repository, in which the CB’s are included to reduce water infiltration and to divert percolating water through the waste material, is proposed to isolate a hazardous waste material or a very low level radioactive waste. A diversion length of the CB which determines a structural dimension of the CB system and plays an important role in designing the shallow land waste depository is well studied by using a test soil box. The second application of the CB will contribute to development of an innovative irrigation technique in the agricultural land field. An effect of the water accumulating in the CB on plant growth is analyzed in the field test. A long-term monitor of soil water in the CB experiment plot constructed in a semi-arid region of West Bank of the Jordan River, Palestine, examines a simple and reliable catchment of infiltrating rainwater in the CB soil. Both applications demonstrate that the CB of soil may be effectively and successfully employed to advance sustainable development in our geo-environmental and agricultural fields.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "162331", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Morii, Toshihiro"}]}, {"nameIdentifiers": [{"nameIdentifier": "162332", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kobayashi, Kaoru"}]}, {"nameIdentifiers": [{"nameIdentifier": "162333", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Fujimaki, Haruyuki"}]}]}, "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": "162328", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "小林, 薫"}], "nameIdentifiers": [{"nameIdentifier": "162329", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "藤巻, 晴行"}], "nameIdentifiers": [{"nameIdentifier": "162330", "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", "download_preview_message": "", "file_order": 0, "filename": "69_33-41.pdf", "filesize": [{"value": "5.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 5600000.0, "url": {"label": "69_33-41.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/28260/files/69_33-41.pdf"}, "version_id": "4cc4732f-b106-41c5-b8d8-a71f35f47188"}]}, "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": "ウォーターハーベスティング", "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": "Water saving irrigation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Water harvesting", "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社会実装を考える", "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社会実装を考える"}, {"subitem_title": "土のキャピラリーバリアの社会実装を考える", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1585"], "permalink_uri": "http://hdl.handle.net/10191/47175", "pubdate": {"attribute_name": "公開日", "attribute_value": "2017-03-23"}, "publish_date": "2017-03-23", "publish_status": "0", "recid": "28260", "relation": {}, "relation_version_is_last": true, "title": ["土のキャピラリーバリアの社会実装を考える"], "weko_shared_id": null}
