First, we present the constructive factors of steppool structures and their appearance, focusing on channel bed profile. Second, we summarize the processes driving the formation and destruction of step-pools, concentrating on current and sedimentation. The untidune and keystone theories are discussed as the key concepts of step-pool formation in relation to the installation of artificial step-pool structures. Third, with reference to previous studies, we discuss the relationship between step-pool structures and river course characteristics. Fourth, we describe the law of resistance and velocity in a mountain river. Finally, with reference to their ecological function, we discuss the use of step-pool structures in restoration projects. Based on earlier studies of step-pool structures, we discuss future issues and propose studies to technologize and standardize step-pool structures for river improvement and restoration.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_21_link_62":{"attribute_name":"研究者情報","attribute_value_mlt":[{"subitem_link_url":"https://hyokadb02.jimu.kyutech.ac.jp/html/100001703_ja.html"}]},"item_21_publisher_7":{"attribute_name":"出版社","attribute_value_mlt":[{"subitem_publisher":"応用生態工学会","subitem_publisher_language":"ja"}]},"item_21_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3825/ece.19.165","subitem_relation_type_select":"DOI"}}]},"item_21_rights_13":{"attribute_name":"著作権関連情報","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 2017 応用生態工学会"}]},"item_21_select_59":{"attribute_name":"査読の有無","attribute_value_mlt":[{"subitem_select_item":"yes"}]},"item_21_source_id_10":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA11528360","subitem_source_identifier_type":"NCID"}]},"item_21_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1344-3755","subitem_source_identifier_type":"PISSN"},{"subitem_source_identifier":"1882-5974","subitem_source_identifier_type":"EISSN"}]},"item_21_text_28":{"attribute_name":"論文ID（連携）","attribute_value_mlt":[{"subitem_text_value":"10429490"}]},"item_21_text_63":{"attribute_name":"連携ID","attribute_value_mlt":[{"subitem_text_value":"12002"}]},"item_21_version_type_58":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"厳島, 怜","creatorNameLang":"ja"},{"creatorName":"Itsukushima, Rei","creatorNameLang":"en"},{"creatorName":"イツクシマ, レイ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{"nameIdentifier":"35469","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"30737656","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000030737656"}]},{"creatorNames":[{"creatorName":"佐藤, 辰郎","creatorNameLang":"ja"},{"creatorName":"Sato, Tatsuro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"西田, 健人","creatorNameLang":"ja"},{"creatorName":"Nishida, Kento","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"真砂, 祐貴","creatorNameLang":"ja"},{"creatorName":"Masago, Yuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"坂田, 知謙","creatorNameLang":"ja"},{"creatorName":"Sakata, Tomonori","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"島谷, 幸宏","creatorNameLang":"ja"},{"creatorName":"Shimatani, Yukihiro","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-05-27"}],"filename":"10429468.pdf","filesize":[{"value":"876 KB"}],"format":"application/pdf","url":{"url":"https://kyutech.repo.nii.ac.jp/record/2000694/files/10429468.pdf"},"version_id":"016eb665-b6b1-4172-b7e3-42af86b960bd"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"step-pool","subitem_subject_scheme":"Other"},{"subitem_subject":"mountain river","subitem_subject_scheme":"Other"},{"subitem_subject":"morphology","subitem_subject_scheme":"Other"},{"subitem_subject":"hydraulics","subitem_subject_scheme":"Other"},{"subitem_subject":"restoration","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"山地河川におけるstep-pool構造に関する既往の知見と河川技術への応用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"山地河川におけるstep-pool構造に関する既往の知見と河川技術への応用","subitem_title_language":"ja"},{"subitem_title":"Existing knowledge about step-pool structures and their application to river engineering in mountain rivers.","subitem_title_language":"en"}]},"item_type_id":"21","owner":"14","path":["24"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-05-27"},"publish_date":"2024-05-27","publish_status":"0","recid":"2000694","relation_version_is_last":true,"title":["山地河川におけるstep-pool構造に関する既往の知見と河川技術への応用"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-05-27T01:53:50.215762+00:00"}
