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_31": {"attribute_name": "フォーマット：mimeタイプ", "attribute_value_mlt": [{"subitem_description": "application/pdf", "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_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": "0037-3818", "subitem_source_identifier_type": "ISSN"}]}, "item_10_source_id_39": {"attribute_name": "NII 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_10_text_66": {"attribute_name": "sortkey", "attribute_value_mlt": [{"subitem_text_value": "03"}]}, "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": [{"nameIdentifier": "39983", "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": "2015-09-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Engineering13-03.pdf", "filesize": [{"value": "2.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 2400000.0, "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"], "permalink_uri": "http://hdl.handle.net/10091/11024", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2011-01-05"}, "publish_date": "2011-01-05", "publish_status": "0", "recid": "13124", "relation": {}, "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_shared_id": -1}
