Jules Dupuit
Arsène Jules-Étienne Juvénal Dupuit (born May 18, 1804 in Fossano , Italy , † September 5, 1866 in Paris ) was a French civil engineer who is also known in the field of economics . He was awarded the Legion of Honor in 1843 .
Dupuit was born in a part of Piedmont that was then part of France, returned to France with his family in 1814 and attended the Louis-le-Grand et Saint-Louis high school in Versailles . He later studied at the École polytechnique and at the École Nationale des Ponts et Chaussées .
From 1827 Dupuit worked in the province as an engineer and in 1842 was chief engineer for the Maine-Loire department. In 1850 he was appointed chief water engineer for the city of Paris.
Dupuit was the first to calculate the cost effectiveness of public works. After the floods on the Loire in 1846, he turned to hydraulic engineering, initially researching flood courses. The fountain formula according to Dupuit-Thiem , which he published in 1863, comes from him . It is used, for example, to determine the permeability coefficient of a groundwater-bearing layer from the subsidence in the well and the amount of water withdrawn.
