The discussed problems are concerned with (1) the agreement of Blue-Johnson's theory with ours, (2) the effect of the breakwater terminus upon the diffracted wave, (3) the secondarily reflected wave and (4) the wave around a single breakwater wing. The agreement of Blue-Johnson's theory with ours is fairly good down to kd=0.5 (k: the wave number, d: half the width of the breakwater gap). For small kd, the strong emission of the secondary wave is found from the shadow of the breakwater. Through the numerical calculation of the wave around the single breakwater wing, it is inquired to what extent the resulting phenomena around the double breakwater wings come from the coupling effect of the two breakwaters.|本報告においては,前報告に引きつづいて間隙をもつた防波堤のまわりにおける長波が論じられている.論ぜらている問題は次のごとくである(1)Blue-Johnsonの理論と筆者の厳密解との一致性,(2)回折波に対する防波堤の効果,(3)2次的な反射波,および(4)単一防波堤のまわりの長波の解析を通して,間隙をもつた防波堤のまわりの長波がどの程度二つの防波堤の相互作用にもとづいているかを調べている.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"130249","nameIdentifierScheme":"WEKO"}],"names":[{"name":"桃井, 高夫"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033362","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":"130248","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":"ji0474005.pdf","filesize":[{"value":"975.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0474005.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33362/files/ji0474005.pdf"},"version_id":"0c1e3c9d-7d41-4133-81f2-dce97f2604f2"}]},"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":"30.
