Yoshimi Goda (Japanese: 合田 良実, Hepburn: Gōda Yoshimi, 24 February 1935 – 19 January 2012) was a Japanese civil engineer who made significant contributions to coastal engineering in Japan and internationally.[1] He undertook a large volume of research on coastal engineering problems, and developed methods for the design of monolithic breakwaters.[2]

Prior to the 1950s, the concept of the significant wave was the fundamental tool used to analyse wave behaviour, in terms of interaction with beaches and coastal engineering structures. Goda was instrumental in the move to characterise the behaviour of sea waves as a random process, involving spectral and statistical analysis, which began to be gradually incorporated into coastal engineering during the 1970s and 1980s. The random wave concept is now used extensively in the engineering of maritime structures.[3]

Life and career

Goda was born in Sapporo in 1935, the son of Ichiji and Umeno (Tanaka) Goda. After graduating in Civil Engineering from The University of Tokyo in 1957, he joined the Port and Harbour Research Institute (PHRI) of the Japanese Ministry of Transport.[1][4] In 1961, he was selected by a Japanese government initiative to conduct research at the Massachusetts Institute of Technology (MIT) in the United States, under the guidance of Professor Arthur T. Ippen. His research at MIT focused on the theoretical analysis of resonance in harbours.[5][6]

In May 1967, he became Head of the PHRI Wave Research Department, and received a doctorate in engineering from the University of Tokyo in 1976, publishing a Ph.D. thesis entitled Study of wave pressure acting on breakwaters.[7] He remained at the PHRI during this time, becoming Director General in 1986. In 1988, he was appointed professor at Yokohama National University, a position in which he remained until retiring in 2000, although he continued to be actively involved with the institution as Professor Emeritus after this date, undertaking research and publishing frequently.[1][8][9][10]

Throughout his career, he made significant contributions to the field of coastal engineering. His most notable work includes the development of a formula for wave pressure.[7][11] He also conducted insightful analysis of random wave transformations, and undertook comprehensive studies on the statistical properties of random seas. These discoveries were incorporated into Japanese standards for designing port and harbour facilities. He published the book Random Seas and Design of Maritime Structures which detailed the concept of random wave processes and spectral behaviour to students and practitioners.[4][12]

Goda also undertook research, published and lectured internationally, attending several international conferences including the International Conference on Coastal Engineering.[4][13]

Amongst the many awards and honours Goda received in his career were the American Society of Civil Engineers International Coastal Engineering Award (1989),[14] the Japan Society of Civil Engineers Publication Award (1997) and Achievement Award (2003),[15] and the Order of the Sacred Treasure (2006).[16] Goda married Toshiko Fukuda in 1959, and the couple had five children.[4][12]

Research and publications

Goda undertook research throughout his career and published widely on coastal engineering topics, including wave overtopping and monolithic breakwaters.[17][13][18]

In 1977, he published the engineering textbook Wave-resistant engineering: Wave-resistant design of harbours and coastal structures[16], which proved popular with coastal engineering students, and was subsequently published in English translation (as Random Seas and Design of Maritime Structures) in 1985, with second and third editions published in 2000 and 2010.[12] He published Introduction to Civil Engineering and Civilization History in 2001, a book aimed at providing a historical overview of the relationship between civil engineering and civilisation.[19]

In 2012, shortly before his death, he published the book Coastal Engineering: Its birth and development, his attempt to summarise developments in coastal engineering from 1950, both in Japan and internationally.[20]
