In the analysis, the incident wave always meets at a sharp angle with the right-hand, breakwater. The most conspicuous features found in the analysis are as follows. A reverse current appears in the windward waters around the terminus of the left-hand breakwater for the wave of long wavelength which is the current against the direction of the incident wave travel. The stagnation point discriminating between the above reversecurrent and the advancing one is in a sense moving away from the breakwater gap along the left-hand breakwater for the increase of the incident angle of the incoming wave. In the analysis concerning the influence of the breakwater wing upon the diffracted wave from the other breakwater, it is found that the wave is reflected from the breakwater shadow.|本報告においては防波堤に対して進入波が斜入射する場合(ここで進入波は常に右手の防波堤と鋭角をなすように与えられている)の論議がなされている.数値解析によって判明した著しい現象は次のごとくである.左手の防波堤端近くの風上側の水域で進入波の進行方向とは逆向きの流れが波長の長い波に対して現われる.そしてこの逆流の規模は進入波の進入角(進入波と右手の防波堤とがなす角)が大きくなるにつれて大きくなってくる.また回析波に対する防波堤端の影響に関する解析において,防波堤の陰から風上側への反射波が見出される.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"130211","nameIdentifierScheme":"WEKO"}],"names":[{"name":"桃井, 高夫"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033351","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162258","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Momoi, Takao"}],"nameIdentifiers":[{"nameIdentifier":"130210","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":"2017-06-26"}],"displaytype":"detail","filename":"ji0475004.pdf","filesize":[{"value":"797.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0475004.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33351/files/ji0475004.pdf"},"version_id":"c156a310-ed87-4826-8e2d-b6ec7793798d"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"40.
