Emile Ganguillet

Emile Oscar Ganguillet (born May 14, 1818 in Cormoret , † May 5, 1894 in Bern ) was a Swiss hydraulic engineer .

Life

After the early death of his father, Emile Ganguillet attended the school in his home village, the Allemann Institute in Kirchlindach near Bern, the Collège in Biel and the Bern upper secondary school. He did not carry out the intended study of theology, but turned to the natural sciences. After working in construction engineering in his home country, he worked for seven years in France.

In Dijon and Besançon he worked on road, bridge and railway construction. In 1847 he returned to his homeland, where he found employment in the civil service and was initially a district engineer. In December 1858 the government elected him chief engineer of the Canton of Bern . He held this position until the spring of 1894.

At the head of Bernese engineering, he led many important works in the field of bridge and hydraulic engineering. His work in the field of hydraulic engineering also includes the studies carried out jointly with Wilhelm Rudolf Kutter on the uniform movement of water in canals and rivers, which were published in 1869.

The Swiss Association of Engineers and Architects offered him honorary membership in September 1893 as an expression of their respect. The investigations by Ganguillet and Kutter are of particular importance for channel hydraulics. The roughness values ​​of the large and small formulas are of the order of magnitude of the Brahms - de Chézy speed coefficient . This created the basis for a general roughness scale.
