Willi H. Hager

from Wikipedia, the free encyclopedia

Willi Hermann Hager (born July 8, 1951 in Uznach ) was adjunct professor at ETH Zurich from 1998 to 2016 . The focus of his research and teaching was in the field of hydraulics and the history of hydraulic engineering.

Live and act

Hager studied civil engineering at the ETH Zurich , which he graduated with a diploma in 1976. After seven years in the wastewater technology sector at the Research Institute for Hydraulic Engineering, Hydrology and Glaciology (VAW) at the ETH, he received his doctorate and in 1983 switched to the Chaire de Constructions Hydrauliques ( hydraulic engineering laboratory) at the ETH Lausanne , to which he remained until 1988. A year later he returned to his alma mater in Zurich, where he was responsible as a scientific adjunct for the management of the VAW's scientific staff. In 1998 he was finally appointed professor, at the same time he became a member of the board of directors of this institute and thus successor to Daniel L. Vischer , who was also his doctoral supervisor .

Hager's research focus was on hydraulics, such as water-sediment flows in river engineering in the case of dike breaches , weft channels and scour processes . He also made a significant contribution to the further development of sewage hydraulics and the historiography of hydraulic engineering. Generously supported by the Swiss National Science Foundation, Hager was able to finance his research; He has published numerous books and articles in English and German language journals.

Hager was honored in 1986 with the VSA Prize for the development of the mobile venturi channel , in 1988 with the Stevens Award , 1994 Best Practice Paper and the Best Technical Note Award from the American Society of Civil Engineers (ASCE), and in 1997 Hager received the Ippen Award from the International Association for Hydraulic Research for its complete work and made an honorary member of the International Association for Water Environment Technology and Research (IAHR) in 2013.
