Third Lyons built aqueduct, it measured 70 km in length, and arrived at the district Fourvière in the current 5th district of Lyon . It is named after the river in the watershed which he fed the Brévenne .Summary1History2Plot3Techniques used3.1Siphon3.2Falls4Flow5Images6References7See also7.1Bibliography7.2Related articles7.3External LinksHistory [ change | modify the code ]The aqueduct Brévenne was built during the reign of Claude .Plot [ edit | edit the code ]elevation profile of the upper part of the aqueduct Brévenne; in particular we notice the two areas of falls and the first siphon.The first collection of the aqueduct is located high enough in altitude (about 600 meters), in the municipality of Aveize .

Your help is welcome!Falls [ change | modify the code ]The ideal average slope was located around 1.5 mm / m, that is to say 1.5 ‰. In addition, the speed of the water was likely to exceed 1 m / s and deteriorate its erosive action by the tunnel. Or aqueduct Brévenne started from a fairly high altitude; its average gradient was 5 ‰ . It was therefore essential to the Romans to break the slope. The chosen solution was to build courts reaches horizontal or low slope, separated by vertical drops made in the wells. These falls were about 2.3 meters to 2.5 meters. Often, many falls, forming a true hydraulic staircase, succeeded as Chevinay , where the water falls from 87 meters just 300 meters away .Flow [ edit | edit the code ]Camille Germain Montauzan believes his speed was the most important of the four works supplying Lyon (28 000 m 3 a day, 324 L / s) , which is now considered the theoretical throughput of the aqueduct . However, John Burdy is more reserved and concedes to work as a discharge of 10 000 m3 per day (115 L / s) in this book , .Pictures [ change | modify the code ]The aqueduct Brévenne to CourzieuThe aqueduct Brévenne in Aqueduct Park in Dardilly .Remains of bridge-siphon boardwalk, Ecully.bridge-siphon reconstitution of boards by Mr. Gabut.References [ change | modify the code ]↑ Camille Germain Montauzan 1908 , "Chapter II - § III. - From Tiberius to Flavian.
