The methods assume that the maximum wave load occurs when the velocity semi-amplitude defined as half the difference between successive negative and positive peaks of the near-bed wave orbital velocity is maximized. The empirical formulas for the velocity-waveform parameters at the maximum velocity semi-amplitude in a random wave train were derived from the near-bed velocities and surface elevations measured in laboratory wave flumes. The laboratory formula for the maximum velocity semi-amplitude was reviewed and improved with near-bed wave orbital velocities and surface elevations estimated from pressure measurements under a wider range of wave conditions in the field. The newly developed formulas for the velocity-waveform parameters at velocity semi-amplitude maxima, combined with the previously developed formulas, showed reasonable agreement with the maximum wave forces measured on the artificial reef models under random waves in a laboratory wave flume as well as with the movement ratio of quarry rocks (median mass = 0.40 t) observed in a field test.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier","subitem_publisher_language":"en"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.oceaneng.2023.114133","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"水産技術研究所 環境・応用部門 水産工学部"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"23341063","subitem_relation_type_select":"Local"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"en","subitem_relation_name_text":"Elsevier:Science Direct"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/abs/pii/S0029801823005176","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"1873-5258","subitem_source_identifier_type":"EISSN"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0029-8018","subitem_source_identifier_type":"PISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_71e4c1898caa6e32","subitem_version_type":"SMUR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Kawamata, Shigeru","creatorNameLang":"en"},{"creatorName":"川俣, 茂","creatorNameLang":"ja"},{"creatorName":"カワマタ, シゲル","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Kawamata","familyNameLang":"en"},{"familyName":"川俣","familyNameLang":"ja"},{"familyName":"カワマタ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Shigeru","givenNameLang":"en"},{"givenName":"茂","givenNameLang":"ja"},{"givenName":"シゲル","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"474","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"50372066","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=50372066"},{"nameIdentifier":"0000-0002-8470-6929","nameIdentifierScheme":"ORCID","nameIdentifierURI":"https://orcid.org/0000-0002-8470-6929"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"International Meteorological and Oceanographic Consultants Co.
