Major ionic components and tritium of groundwater were determined to infer the behavior of groundwater on landslides. Water samples were classified into four groups according to the major ion compositions using the Durov-diagram and by reference to their geographical distribution. Those are 1.NaHCO_3 type water found in landslide area, 2.Na^+ -Cl^-, HCO^-_3, SO^<-->_4 type water found around the landslide, 3.Ca^<++>, Mg^<++> -Cl^-, HCO^-_3, SO^<-->_4 type water found in foot hill, and 4.Na_2SO_4 type water obtained from the well in the landslide area in 1986. The sodium bicarbonate waters from bore holls in the landslide area were the result of dissolution process of Na-montmorillonite and other water from outside of the landslide were the result of dissolution of kaolinite. The water collected after one year from the landslide disaster changed from NaHCO_3 type water to Na_2SO_4 type water by oxidation of sulfur compounds under oxidative conditions formed by a disturbance of the soil. T-concentrations of some samples were higher than annual mean T-concentration of precipitation in 1985. This fact suggests that these samples originate from the precipitation during the atmospheric detonations of thermonuclear devices (1961-1968). This period accords with the active period of the Jitsukeyama landslide. Some parts of the groundwater in the landslide area were recharged by the precipitation of pollutants caused by the detonation of hydrogen bomb.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"161786","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sato, Osamu"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学積雪地域災害研究センター"}]},"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":"AN00183327","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03877892","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐藤, 修"}],"nameIdentifiers":[{"nameIdentifier":"161785","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":"8_57-69.pdf","filesize":[{"value":"933.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"8_57-69.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28147/files/8_57-69.pdf"},"version_id":"1c6670e9-3493-43fb-b148-8f5351ebf8c5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"landslide","subitem_subject_scheme":"Other"},{"subitem_subject":"groundwater","subitem_subject_scheme":"Other"},{"subitem_subject":"waterquality","subitem_subject_scheme":"Other"},{"subitem_subject":"tritium","subitem_subject_scheme":"Other"},{"subitem_subject":"地すべり","subitem_subject_scheme":"Other"},{"subitem_subject":"地下水","subitem_subject_scheme":"Other"},{"subitem_subject":"水質","subitem_subject_scheme":"Other"},{"subitem_subject":"トリチウム","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":"長野市地附山地すべり地の地下水の水質 : 地すべり地の陸水の水質 6","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"長野市地附山地すべり地の地下水の水質 : 地すべり地の陸水の水質 6"},{"subitem_title":"長野市地附山地すべり地の地下水の水質 : 地すべり地の陸水の水質 6","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1575"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-03-03"},"publish_date":"2016-03-03","publish_status":"0","recid":"28147","relation_version_is_last":true,"title":["長野市地附山地すべり地の地下水の水質 : 地すべり地の陸水の水質 6"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:09.057011+00:00"}
