“James Eamonn Nash graduated as a civil engineer from Galway University in 1949 and started work with the Irish Electricity Supply Board for dam engineering. Right from the beginning, Nash collaborated with the hydrologist J.C.I. Dooge and remained his friend during his lifetime. In 1955, Nash obtained the Master degree of Engineering from Galway University for a work relating to flood propagation in rivers. One year later, Nash moved to HR Wallingford and developed the Instant Unit Hydrograph IUH Method, for which his name became famous. The IUH was represented by the gamma function and linearly relates flows in basic catchments. The paper was awarded the Telford premium by the Institution of Civil Engineers, London, in 1958. The IUH was applied with success to British catchment areas in the early 1960s.
After a two-years stay in Nigeria, Nash returned to Wallingford but soon after took the position of senior lecturer at Galway University. He was one of the founders of the Journal of Hydrology in 1963. In 1970 he submitted a PhD thesis and was appointed professor of engineering hydrology. From 1979 Nash organized the International postgraduate hydrology courses, with a large number of students from all continents until 2000. Nash was awarded the honorary doctorate from the University of Nanching, the International Premium of the International Association of Hydrological Sciences IAHS in 1989, and the 1999 Ven Te Chow award from ASCE for his groundbreaking investigations in hydrologic engineering and innovative solutions of hydraulic problems.”
