Scolmatore dell'Arno

Lo Scolmatore dell'Arno (The Arno floodway) is a 28 kilometers (17 mi) artificial flood control channel of the river Arno from Pontedera to the Ligurian Sea at Calambrone. As a consequence of the Arno flood of 1949, it was decided to start the construction of Scolmatore dell'Arno in 1954 at a cost of more than 10 billion lire of the time. The work was not completed in time for the disastrous flood of 1966 that, in addition to Florence, caused enormous damages in Pontedera and Pisa. The floodway branches off the Arno 40 km from the river mouth (28 kilometers (17 mi) off the coast), just downstream Pontedera in a southwesterly direction, where the Arno proper continues towards northwest. The elevation at the bifurcation is 11 meters (36 ft), with the floodway's main ingate controlled by four gates that during normal water levels are closed, whereas a secondary and smaller ingate has free flow. The main channel has a total length of 28.3 kilometers (17.6 mi) and after a bend 8 kilometers (5.0 mi) downstream it continues almost straight towards the sea in a west-southwest direction. The lower 6 kilometers (3.7 mi) forms the border between the provinces of Livorno and Pisa, and the mouth is situated between Calambrone and the seaport of Livorno, 11 kilometers (6.8 mi) south of Arno proper's mouth. Scolmatore dell'Arno has a few branches, most notably is the much older Navicelli cha
