The Tagliamento (Italian: [taʎʎaˈmento]; Friulian: Tiliment; Venetian: Tajamento) is a braided river in north-east Italy, flowing from the Alps to the Adriatic Sea at a point between Trieste and Venice.

)[1][2] For this reason, it has been the subject of many scientific investigations into its peculiar characteristics: these include its 150 km long corridor which connects the Alps and the Adriatic Sea, its unconstrained floodplain, which hosts several aquatic and terrestrial habitats, and its over 600 islands.

The river passes through Pinzano and courses in a southward direction, while spreading across the plain reaching a width of 3 kilometres (1.9 mi) near Spilimbergo and splitting into a number of branches.

From here onwards, the river bed distinctly narrows to 180 metres (590 ft) and starts to meander because of the reduced slope.

The Standard Friulian name for the river is Tiliment; other local variants include Taiament, Tilimint, Tiument, Timent, and Tuement.
