It is the second Italian river by length after the Po, the third for its watershed after the Po and the Tiber, and the fourth by its mean yearly discharge after the Po, the Ticino and the Tiber.



The Adige river has a length of 410 km (254.8 mi) and a drainage basin with an area of 12,200 km2 (4,710 sq mi).[1]

Its average yearly discharge (volume of water which passes through a section of the river per unit of time) is 205 m3/s (7,200 cu ft/s) at Boara Pisani, a comune in the Padua province near the mouth of the river.[2]

Average monthly discharge (m3/s) at Boara Pisani (1961 - 1970)[2]



The Adige starts in the Reschen Pass in the comune of Graun im Vinschgau, South Tyrol province, at an altitude of about 1,550 m (5,085 ft) close to the borders with Austria and Switzerland. First, it flows to the south until the confluence with the Ram river and then turns to the east. At Merano, the Adige is joined by the Passirio river and turns to the southeast; in Bolzano, it is joined by the Isarco, its main tributary. In the confluence with the Tasso river, the Adige flows to the south and, then, from Badia Polesine, it turns to the east and flows into the Adriatic Sea to the south of the mouth of the Brenta river and to the north of the mouth of the Po river.[1]

The valley of the Adige gets several names: Venosta valley between the source and Merano, Adige valley between Merano and Trento, Vallagarina between Trento and Verona and, last, Padana valley between Verona and the mouth.
