Namely, these destructions are more intensified by the damupped backwater which is caused by flow-timbers checked by bridge piers at the peak time of a flood. The farther the river runs down, the heavier the damage becomes by flow-timbers. Therefore, if the peak time of flow-timbers can be retarded later than that of flood-discharge, the disaster on riverstructures will considerably be decreased. Accordingly, to check flow-timbers is as much important mission charged to the upper reaches of a river as to check flow-stone and -sand. The author consulted with the authorities concerned of Nagano Prefecture who have serious concerns about the above-mentioned and adopted the following proposals, A and B, as a practical plan for checking flow-timbers, and he tried a hydraulic experiment in using a model channel (see Fig. 1) to make it realize. A : a proposal to avail the sub-check-dam and set a leading gate, B a proposal to set a leading net. The results of the experiment may simply be stated as follows :A. (1) The checking-ratio=(U+W)/(T+U+V+W). Where, T :the number of the flow-timbers stopped on the bottom at the upper stream from the leading gate, U : do. drifting along the gate, V do. flowing down under the gate, W : do. caught into the pocket of the sub-check-darn. The details relating to U, V and W will be understood in Figs. 6～15 of this paper.","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":"信州大学工学部紀要 13: 59-90 (1962)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学工学部"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0037-3818","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":"AN00121228","subitem_source_identifier_type":"NCID"}]},"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":"佐々木,  八郎","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"Engineering13-03.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Engineering13-03.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/13124/files/Engineering13-03.pdf"},"version_id":"c323b68a-c7ce-4fcc-bc50-ae383763d62d"}]},"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":"砂防ダム附近における流木阻止に関する実験的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"砂防ダム附近における流木阻止に関する実験的研究","subitem_title_language":"ja"},{"subitem_title":"An Experimental Study on Checking of Flow-Timbers neighbouring Check-Dam","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1294"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-01-05"},"publish_date":"2011-01-05","publish_status":"0","recid":"13124","relation_version_is_last":true,"title":["砂防ダム附近における流木阻止に関する実験的研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-16T04:46:44.094958+00:00"}
