The paper also provides a stochastic analysis, based on simulation using probable rainfalls at different levels and a runoff model, on flood mitigation and its effect on flooding downstream of the pond. The results show that: 1) the rainfall pattern in heavy rains is mostly similar to the hyetograph which has its peak at the center of the rainfall duration time, 2) the flood peaks in the overflow of the pond are decreased by 37-98%, for 4 cases of high flood with the maximum 10-minute rainfall intensity of 10 mm or more, 3) the percentage of mitigation is strongly influenced by the amount of vacant storage capacity at the beginning of the flood, 4) the flood mitigation ratio in floods with a return period of 5-200 years ranges from 37 to 43% of the peak inflow, even under the condition of full water level at the beginning of flood, 5) the pond reduces the frequency of inundation downstream from more than once every year to once every two years, 6) the lowering of water level in the pond during the flood season is effective for flood mitigation.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00002061","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人 農業・生物系特定産業技術研究機構 農村工学研究所"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00002061","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1882-3262","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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":"加藤, 敬"},{"creatorName":"カトウ, タカシ","creatorNameLang":"ja-Kana"},{"creatorName":"KATO, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"5682","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":"2019-03-20"}],"displaytype":"detail","filename":"nkk_report_No44p1-22p.pdf","filesize":[{"value":"678.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nkk_report_No44p1-22p.pdf","url":"https://repository.naro.go.jp/record/2156/files/nkk_report_No44p1-22p.pdf"},"version_id":"a1d67a0f-d09a-4f1b-befb-87138e02ee14"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"農業用ため池","subitem_subject_scheme":"Other"},{"subitem_subject":"洪水低減機能","subitem_subject_scheme":"Other"},{"subitem_subject":"水文水理学的研究","subitem_subject_scheme":"Other"},{"subitem_subject":"Irrigation pond","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Flood","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Flood mitigation function","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Actual rainfall","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Rainfall pattern","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Skewness","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Hyetograph","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Vacant storage capacity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Evaluation","subitem_subject_language":"en","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":"農業用ため池の洪水低減機能に関する水文・水理学的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"農業用ため池の洪水低減機能に関する水文・水理学的研究"},{"subitem_title":"Flood Mitigation Function and its Stochastic Evaluation of Irrigation Ponds : Evaluation of Flood Mitigation Function of the Matsuzawa-ike Pond, Osaka Prefecture, Japan","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"12","path":["222"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-22"},"publish_date":"2019-03-22","publish_status":"0","recid":"2156","relation_version_is_last":true,"title":["農業用ため池の洪水低減機能に関する水文・水理学的研究"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2023-05-15T16:35:52.037133+00:00"}
