PARMAKIAN

PARMAKIAN 09.09. 1908 Watertown MA/USA 15.08. 1994 Denver CO/USA John Parmakian was educated at the Massachusetts Institute of Technology MIT, Cambridge MA, with a BS degree in civil engineering in 1930, and the MS degree in 1939 from the University of Colorado, Fort Collins CO. He was from 1930 to 1940 an engineer with the US Bureau of Reclamation USBR, and a field and test engineer of mechanical equipment there until 1946, from when he was a technical engineer of its Analytical Section. Parmakian was member of the American Societies of Mechanical Engineers ASME and Civil Engineers ASCE. In his position as chief of the USBR Technical Engineering Analysis Branch Parmakian directed, coordinated and reviewed the activities of a group of highly-specialized engineers in the technical analysis of complex problems pertaining to the design and the construction of dams, hydro-electric plants and pumping schemes. He had published a number of papers in engineering and military journals in the fields of vibrations in hydraulic structures, hydraulic transients, and applied mathematics. He also authored the book Waterhammer analysis. After retirement from the USBR he was a consultant for a variety of international and domestic firms on aspects of hydropower plants, pumped storage, and general power plant engineering. In ASME he was elected to the Executive Committee of the Hydraulic Division in 1955, chairing it from 1958 to 1959. Later, he was chairman of the Waterhammer Sub-Committee and also a member of the Hydraulic Prime Movers and Cavitation Sub-Committees. Parmakian was Fellow of both ASME and ASCE. He was cited for superior accomplishment in solving complex stress and hydraulic design problems and for his work on the waterhammer problem in power penstocks. Anonymous (1952). John Parmakian.

PARMLEY 08.12. 1862 Rock County WI/USA 19.02. 1934 Upper Montclair NJ/USA Walter Camp Parmley was educated at University of Wisconsin, Madison WI, from where he obtained the MS degree in civil engineering in 1893. After graduation as a civil engineer in 1887, he went to California opening an office at San Bernardino, to practice in a partnership. The firm was immediately successful, with works including surveys and the construction of the Jurupa Canal and the Vivienda Pipeline, together with other irrigation systems. In 1889 Parmley became assistant engineer on the Bear River Canal Project in Utah, thereby being involved in the water works of Ogden UT. After graduation in 1893 he was assistant city engineer of Peoria IL until 1896, was a sanitation engineer for Cleveland OH until 1903, from when he had a private consulting office in New York City. He was a member of the American Society of Civil Engineers ASCE, and a president of the Cleveland Engineering Society. Parmley was remembered for his pleasing personality and for his dependability, both in business matter and socially. He was a man of fine character, unassuming, always cheerful, and always kind. Parmley had specialized in large sewer designs during his stay in New York City as a consultant. He invented thereby reinforced concrete pipes and segmental construction and special arching reinforcing methods, particularly for tunnel construction. Parmley authored a number of articles in the then most important American civil engineering journals, including the ASCE journals or Engineering News-Record. These dealt with questions in sewerage engineering including the rainfall-runoff phenomena for sewer design purposes, and descriptions of particular wastewater treatment stations. Anonymous (1931).
