ROHRINGER

HUNGARY (see also List of Individuals)

\

28.3.1868 Kassa/H - 4.5.1945 Budapest/H

\

Sandor (Alexander) Rohringer started his career in civil engineering with improvements of Vág River and the rehabilitation of Recina Torrent in Fiume, today's Rijeka in Croatia, then the only harbor of the Austrian Empire. From 1909 to 1918 Rohringer directed a surveyor's office in Kassa, today's Košice in Slovakia. He was appointed in 1923 professor of hydraulic engineering of Budapest Technical University, from where he retired in 1939. Rohringer passed away at the end of World War II after the long siege by the Russians.

Rohringer designed the first hydraulic laboratory of Hungary at the Budapest University of Technology. Earlier, he was interested in a system of a well network in the Puzsta, the large plain in the East of the capital, for observing the daily groundwater variations. Rohringer contributed to the understanding of river meandering with papers published in the International Navigation Congresses. He verified findings of Louis Fargue (1827-1910) relating to the so called Fargue rules for river meanders. Rohringer also made early scour observations relating to bridge pier and bridge abutment elements of different shapes to test the effect of element geometry on the scour depth. Another work related to a sand trap that was also investigated hydraulically, given the complex flow patterns in such two-phase flows. Rohringer was a Member of the Board of the journal Vízügyi Közlemények from 1923. He was elected associated Member of the Hungarian Academy of Sciences first and later promoted to full Member. Rohringer's activities were not only confined to his country because he sought international contact and was active for some time also in Turkey.
