This species is endangered due to the introduction of other non-indigenous trout species sometime between World War I and World War II. The river is also well known for the marble trout ( Salmo marmoratus) this species is native to rivers of the northern Adriatic basin, and it lives in the upper course of the river. This region served as a location for the 2008 Disney film Chronicles of Narnia: Prince Caspian. The river inspired the poet Simon Gregorčič to write his best-known poem Soči ( To the Soča), one of the masterpieces of Slovene poetry. Giuseppe Ungaretti, one of the greatest Italian poets, describes the Isonzo in the poem 'The Rivers.' Attractions ĭue to its emerald-green water, the river is marketed as 'The Emerald Beauty.' It is said to be one of the rare rivers in the world that retain such a colour throughout their length. The former estuary (of the Aesontius, and the early Isonzo) in the newly formed lagoon of Grado became an independent coastal rivulet. The original subterranean discharge of the Bontius into the Timavo became obstructed, and another avulsion returned the new watercourse into the bed of the lower Natisone.ĭuring the next centuries the estuary of this new river-the Soča-moved eastward until it captured the short coastal river Sdobba, through which the Isonzo now discharges into the Adriatic Sea. In 585, a landslide cut off the upper part of the Natisone riverbed, causing its avulsion and subsequent stream capture by the Bontius River. According to the Roman historian Strabo, the river named Aesontius, which in Roman times flowed past Aquileia to the Adriatic Sea, was essentially the Natisone and Torre river system. The present course of the river is the result of several dramatic changes that occurred during the past 2,000 years. During World War I, it was the scene of bitter fighting between the two countries, culminating in the Battle of Caporetto in 1917.

Prior to the First World War, the river ran parallel to the border between Kingdom of Italy and the Austro-Hungarian Empire. It has a nival-pluvial regime in its upper course and pluvial-nival in its lower course. The river runs past the towns of Bovec, Kobarid, Tolmin, Kanal ob Soči, Nova Gorica (where it is crossed by the Solkan Bridge), and Gorizia, entering the Adriatic Sea close to the town of Monfalcone. Īn Alpine river in character, its source lies in the Trenta Valley in the Julian Alps in northwestern Slovenia, at an elevation of 876 metres (2,874 ft). The Soča ( pronounced in Slovene) or Isonzo ( pronounced in Italian other names Friulian: Lusinç, German: Sontig, Latin: Aesontius or Isontius ) is a 138-kilometre (86 mi) long river that flows through western Slovenia (96 kilometres or 60 miles) and northeastern Italy (43 kilometres or 27 miles).
