The depth of the soil was 30cm on Plot 1 and 50cm on Plot 2. The following are new interpretations obtained by the observations. (1) Rain water infiltrates to the bedrock layer and runs off from a saturated zone formed on this layer. (2) The time to reach a steady hydrographic state decreases with an increase of the rain-fall intensity and initial discharge. (3) The maximal value of the recession coef-ficient occurs between 10 minutes and 1 hour after the end of a rainfall, but afterward these values become constant at each time step regardless of rainfall intensity. (4) The observed hydrograph and these tendencies can be expressed by a model which estimates the process of infiltration as one-dimensional transient saturated-unsaturated flow.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"72862","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OHTA, Takeshi"}]},{"nameIdentifiers":[{"nameIdentifier":"72863","nameIdentifierScheme":"WEKO"}],"names":[{"name":"FUKUSHIMA, Yoshihiro"}]},{"nameIdentifiers":[{"nameIdentifier":"72864","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUZUKI, Masakazu"}]}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本森林学会"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-485X","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学農学部"},{"subitem_text_value":"京都大学農学部"},{"subitem_text_value":"京都大学農学部"}]},"item_16_version_type_27":{"attribute_name":"著者版フラグ","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":"太田, 岳史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"福嶌, 義宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鈴木, 雅一"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"jjfs-v65n4p125-134.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jjfs-v65n4p125-134.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9328/files/jjfs-v65n4p125-134.pdf"},"version_id":"197fcb9c-3c78-4185-af97-eb1fd0287fca"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"一次元鉛直不飽和浸透を用いた雨水流出特性の検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"一次元鉛直不飽和浸透を用いた雨水流出特性の検討"}]},"item_type_id":"16","owner":"3","path":["1510"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-02-01"},"publish_date":"2012-02-01","publish_status":"0","recid":"9328","relation_version_is_last":true,"title":["一次元鉛直不飽和浸透を用いた雨水流出特性の検討"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:05:52.806630+00:00"}
