It is necessary for disaster prevention, to evaluate suitably the storm water hydrologic process on a hillslope and predict the occurrence of slope failure. Recently, numerical simulation model composed with saturated- unsaturated infiltration analysis and slope stability analysis, is used frequently to predict slope failure. However, much time become necessary in order to calculate unsaturated infiltration process of storm water, and setting input data to these models need much labor. In order to understand the process of rainfall infiltration, ascent of the ground-water level and changes of mean saturation ratio on the soil layer, in this study the vertical infiltration experiments were executed using the large scale undisturbed soil sample collected in the study basin where is located in the western site of KOCHI Prefecture. The relationship between the ground-water level and the mean saturation ratio on the soil layer was grasped based on results of these experiments. This relation can be expressed by the following equations; H/D =Lr・(Sr - Scr); Sr =0.001・R＋0.7689; Lr =0.0236・R＋4.2705 ;D≦30cm; Lr1 =0.0554・R＋5.7824 ;D＞30cm, 0.0≦H/D≦0.4; Lr2 =0.0239 ・R＋3.2633 ;D＞30cm, 0.4＜H/D≦1.0 Where H and D is the ground-water level and the depth of soil layer. Sr and Scr is the saturation ratio on the soil layer and the critical saturation ratio for ground-water level occurrence, respectively. R is the rainfall intensity. Lr is the inclination of H/D-Sr curve. The effectiveness of these equations (H-Sr model) was confirmed by applying these to reappearance calculation of the vertical infiltration experiments and slope stability analysis.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_description_30": {"attribute_name": "資源タイプ（コンテンツの種類）", "attribute_value_mlt": [{"subitem_description": "Article", "subitem_description_type": "Other"}]}, "item_10_description_5": {"attribute_name": "引用", "attribute_value_mlt": [{"subitem_description": "信州大学農学部紀要 48（1-2）: 29-38(2012)", "subitem_description_type": "Other"}]}, "item_10_link_3": {"attribute_name": "信州大学研究者総覧へのリンク", "attribute_value_mlt": [{"subitem_link_text": "平松, 晋也", "subitem_link_url": "http://soar-rd.shinshu-u.ac.jp/profile/ja.OCSaOmDh.html"}, {"subitem_link_text": "福山, 泰治郎", "subitem_link_url": "http://soar-rd.shinshu-u.ac.jp/profile/ja.HVkmPUkh.html"}]}, "item_10_publisher_4": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "信州大学農学部"}]}, "item_10_select_64": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_35": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0583-0621", "subitem_source_identifier_type": "ISSN"}]}, "item_10_source_id_39": {"attribute_name": "NII ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0583-0621", "subitem_source_identifier_type": "ISSN"}]}, "item_10_source_id_40": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00121352", "subitem_source_identifier_type": "NCID"}]}, "item_10_text_66": {"attribute_name": "sortkey", "attribute_value_mlt": [{"subitem_text_value": "04"}]}, "item_1627890569677": {"attribute_name": "出版タイプ", "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": "平松,  晋也"}], "nameIdentifiers": [{"nameIdentifier": "33124", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "宮前,  崇"}], "nameIdentifiers": [{"nameIdentifier": "33125", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "木下,  貴裕"}], "nameIdentifiers": [{"nameIdentifier": "33126", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "福山,  泰治郎"}], "nameIdentifiers": [{"nameIdentifier": "33127", "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": "2015-09-25"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Agriculture48-04.pdf", "filesize": [{"value": "1.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 1300000.0, "url": {"label": "Agriculture48-04.pdf", "url": "https://soar-ir.repo.nii.ac.jp/record/10460/files/Agriculture48-04.pdf"}, "version_id": "c45e2b66-d1e1-4bbc-8ae9-0170199b80b9"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "飽和度", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Saturation ratio", "subitem_subject_scheme": "Other"}, {"subitem_subject": "鉛直浸透実験", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Vertical infiltration experiment", "subitem_subject_scheme": "Other"}, {"subitem_subject": "地下水深", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Ground-water level", "subitem_subject_scheme": "Other"}, {"subitem_subject": "斜面安定解析", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Slope stability analysis", "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": "飽和度を指標とした地下水深の簡易推定手法に関する実験的研究", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "飽和度を指標とした地下水深の簡易推定手法に関する実験的研究", "subitem_title_language": "ja"}, {"subitem_title": "Experimental Study on Simple Set up Method of Ground-Water Level Using Saturation Ratio in Soil Layer as an Index", "subitem_title_language": "en"}]}, "item_type_id": "10", "owner": "1", "path": ["1023"], "permalink_uri": "http://hdl.handle.net/10091/15716", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2012-04-17"}, "publish_date": "2012-04-17", "publish_status": "0", "recid": "10460", "relation": {}, "relation_version_is_last": true, "title": ["飽和度を指標とした地下水深の簡易推定手法に関する実験的研究"], "weko_shared_id": -1}
