WAGNER A.J.

WAGNER A.J. 12.01. 1912 Hillsboro WI /USA 14.07. 1990 Knoxville TN/USA Aubrey Joseph Wagner received the BS degree in civil engineering from the University of Wisconsin, Madison WI, in 1933. He began in 1934 his long and distinguished career with the Tennessee Valley Authority TVA, which had been founded one year before. He first worked in the navigation program, being involved in the planning and the construction of the Tennessee River navigation facilities. In 1948 he was appointed chief of the TVA Navigation and Transportation Branch, where he was responsible for both engineering and economic studies with an account on the commercial use of the then improved Tennessee waterway. He was in 1951 appointed TVA assistant general manager, and general manager in 1954, so that he was the agency’s chief administrative officer. In 1961, President Kennedy appointed Wagner to the TVA Board of Directors, and next year to its chairman, a position he held until 1978, longer than anyone else who had been chairman. During his tenure, he gained a degree of respect and personal loyalty among the TVA employees; he was called ‘Mr. TVA’ by many. He is remembered for his tireless energy, never letting up until he accomplished what he was trying to do. Although he could be stubborn when he was convinced he was right, he would listen to others and worked hard to gain broader perspectives. He also saw TVA’s projects as tools to create good jobs and build a better quality of life for the Tennessee Valley. Today people who travel to the Valley can see the legacy he left behind. He was elected to the National Academy of Engineering in 1973, and was the recipient of many awards. Anonymous (1968). TVA chairman A.J. Wagner. Engineering News-Record 180(May23): 50.

WAGNER W.E. 24.01. 1915 Mancos CO/USA 25.07. 2000 Morrison CO/USA William Emory Wagner joined the US Bureau of Reclamation USBR in 1946, after having obtained degrees from Colorado State College and University of Colorado, Fort Collins CO. He spent his career with USBR until retirement in 1974, finally as chief of the Hydraulics Branch of the General Research Division. He received then the Meritorious Service Award from the US Department of Interior. Wagner contributed a number of outstanding papers to the knowledge of spillway flow. His 1956 paper deals with the so-called morning glory spillway, corresponding to a circular-crested intake connected with a vertical shaft and a 90° bend at its base, by which flood floods are discharged to an outlet structure. These spillways may be operated both free and submerged, but it was already found out in the 1940s that only free flow is adequate because of hydraulic control, cavitation damage, and unstable flow features. Despite the morning glory spillway was introduced around 1900, and there were notable research works for instance by Ford Kurtz (1885-1956) in 1925 or by William J.E. Binnie (1867-1949) in the 1930s, Wagner considered the flow features of the vertical sharp-crested circular pipe to find the lower and upper jet trajectories under fully-aerated conditions. He also determined the discharge coefficient versus the relative head on the weir, the effect of vacuum below the intake, and the effect of the approach flow velocity, resulting in an almost complete study of these flows, provided there is absolutely no rotational approach flow component. He then proceeded to the definition of the crest geometry, in analogy to the standard-crested weir with a straight weir crest. This paper was awarded the 1957 J. James Croes Medal from ASCE.
