The Isonzo/Soča (Slovene: Soča; Italian: Isonzo; Friulian: Lusinç[3]) is a river that flows through western Slovenia and northeastern Italy.

An Alpine river in character, its source lies in the Julian Alps in Slovenia and enters the Adriatic Sea close to the Italian town of Monfalcone.

The Soča river has a length of 138 kilometres (86 miles), 96 kilometres (60 miles) in Slovenia and 43 kilometres (27 miles) in Italy.[4]

Its drainage basin has a pronounced mountainous character with an average elevation of about 599 metres (1,965 feet) above sea level,[5] and an area of 3,400 square kilometres (1,313 square miles), 2,250 square kilometres (869 square miles) (66%) in Slovenia and 1,150 square kilometres (444 square miles) (34%) in Italy.[5]

The watershed of this river is one of the few places where the Marble trout (Salmo marmoratus) is found.[6]

Course of the Soča/Isonzo

The source of the Soča lies in the Trenta Valley in the Julian Alps in northwestern Slovenia, at an altitude of 876 metres (2,874 feet).[4] The river flows through the Triglav National Park where is the mountain Triglav (2,864 m), the highest mountain in the Julian Alps and in the country. Then it flows to the south past the Slovenian towns of Bovec, Kobarid, Tolmin, Kanal ob Soci and Nova Gorica (where it is crossed by the Solkan Bridge); here, at an altitude of 56 metres (184 feet),[4] the river crosses the border and gets into Italy.

In Italy, the Soča, now called Isonzo, flows through several comuni of the Friuli-Venezia Giulia region. Theses comuni are:

Finally, it flows into the Gulf of Trieste (Adriatic Sea) in the Riserva Naturale della Foce dell'Isonzo ("Natural Reserve of the Mouth of the Isonzo"), to the southwest of the town of Monfalcone.
