The Tanaro (pronounced ‘Tànaro’), known as Tanarus in ancient times, is a 276 km-long river in north-western Italy. It rises in the Ligurian Alps, close to the border with France and is the most significant right-side tributary to the Po in terms of length, size of drainage basin (partly Alpine, partly Apennine) and discharge. The Ligurian Alps are a mountain range in Italy. ...

The Tanaro proper begins in Liguria at the confluence of two small torrents whose sources are in Piedmont: the Tanarello and the Nerone. Liguria is a coastal region of north-western Italy, the third smallest of the Italian regions. ...

The main source of the Tanarello is on the slopes of Monte Saccarello above Monesi, a village belonging to the commune of Triora (IM). This mountain straddles the French département of Alpes-Maritimes, the Piedmontese province of Cuneo and the Ligurian province of Imperia and marks the juncture of the watersheds between three drainage basins: that of the Tanaro itself, that of the Roya (Italian Roia), which rises in France but enters the sea at Ventimiglia; and the Argentina which flows into the Ligurian Sea at Taggia.

Regime The discharge is subject to a great deal of seasonal variation. Although, uniquely among the Po’s right-side tributaries, the river has an Alpine origin, the Ligurian Alps are of an insufficient altitude, and too close to the sea, to allow for the formation of snow fields or glaciers large enough to provide a steady source of water during the summer. Furthermore the Alpine zone forms only a part of the basin drained by the Tanaro. The seasonal regime of the river is therefore more typical of an Appenine torrent, with a maximum discharge (which can reach 1,700 m³/s) in spring and autumn and a very small rate of flow in the summer. Austrias longest glacier, the Pasterze, winds its 8 km (5 mile) route at the foot of Austrias highest mountain, the Grossglockner A glacier is a large, long-lasting river of ice that is formed on land and moves in response to gravity. ...

Flood events The river is highly prone to flooding. During the two hundred year period 1801–2001 parts of the Tanaro basin were affected by floods on 136 occasions, the most devastating being those of November 1994 when the whole of the river valley was affected by severe flooding and the town of Alessandria was especially stricken.
