Richards' potential equation supplemented by appropriate boundary and initial conditions is described and formulated on the basis of Galerkin-type finite element method in conj unction with a fully implicit iterative scheme. SUSFEM calculates sequential and spatial variations of pressure head in soil, h. The saturated water movement is predominant in the region where h>0 and the unsaturated flow in the region where h<0. An equi-potential line corresponding to h=O is defined as a free surface of seepage, a water table of groundwater, or a saturated water bulb of infiltration which happens to separate the saturated and unsaturated zones in the soil. Applicability of SUSFEM is examined fairly well by comparing with a laboratory experiment and a computer program published in the literatures. Then SUSFEM is applied to investigate a constant-head infiltration from a single ring measured in sand soil field. It provides good predictions of the infiltration rate into the soil as well as the water movement in the soil with employing saturated hydraulic conductivity determined by field permeability test.","subitem_description_type":"Abstract"},{"subitem_description":"二次元または軸対称条件下の不飽和土、部分飽和土あるいは飽和土における水分挙動を予測するためのコンピュータプログラムSUSFEMを開発した。Richardsのポテンシャル方程式と初期および境界条件を説明し、Galerkin有限要素法と繰返し計算手法を用いて定式化した。SUSFEMにより、土壌中の圧力水頭hの時間的、空間的変化を計算することができる。h>0の領域では飽和流れが、h<0の領域では不飽和流れが卓越することになる。浸透流の自由水面や地下水面、浸潤流れの飽和水分球根は、h=0に対応する点を連ねた等ポテンシャル線として定義され、単に土壌中の飽和領域と不飽和領域とを区分するだけの物理的意味しかもたない。SUSFEMの実務性を、公表されている室内実験結果およびコンピュータプログラムとの比較により検証した。次いで、SUSFEMを、砂地ほ場で測定した単一リングからの定水頭浸潤挙動の分析に適用した。ほ場透水試験からえられた飽和透水係数を用いることにより、頭浸流量ならびに土壌中の水分挙動を良好に予測できた。","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"164017","nameIdentifierScheme":"WEKO"}],"names":[{"name":"森井, 俊広"}]}]},"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":"Morii, Toshihiro"}],"nameIdentifiers":[{"nameIdentifier":"164016","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":"KK_52(1)_41-54.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KK_52(1)_41-54.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28513/files/KK_52(1)_41-54.pdf"},"version_id":"1ca5440d-98e3-49e6-8bb9-0f888ff5c502"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Water movement in soil","subitem_subject_scheme":"Other"},{"subitem_subject":"Richards' potential equation","subitem_subject_scheme":"Other"},{"subitem_subject":"Finite element method","subitem_subject_scheme":"Other"},{"subitem_subject":"Computer program","subitem_subject_scheme":"Other"},{"subitem_subject":"Field permeability test","subitem_subject_scheme":"Other"},{"subitem_subject":"土壌中の水分挙動","subitem_subject_scheme":"Other"},{"subitem_subject":"リチャードのポテンシャル方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"有限要素法","subitem_subject_scheme":"Other"},{"subitem_subject":"コンピュータプログラム","subitem_subject_scheme":"Other"},{"subitem_subject":"ほ場透水試験","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Prediction of Water Movement in Soil by Finite Element Method","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Prediction of Water Movement in Soil by Finite Element Method"},{"subitem_title":"Prediction of Water Movement in Soil by Finite Element Method","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1618"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-01-31"},"publish_date":"2012-01-31","publish_status":"0","recid":"28513","relation_version_is_last":true,"title":["Prediction of Water Movement in Soil by Finite Element Method"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:42.152255+00:00"}
