The Hers-Vif rises at an elevation of about 1,500 metres (4,900 ft) near the Chioula Pass of the Pyrenees, approximately 6 kilometres (4 mi) north of Ax-les-Thermes. It is the major tributary of the Ariège into whose right bank it flows 2 kilometres (1.2 mi) upstream from Cintegabelle in the Haute-Garonne.

It flows some 30 kilometres (19 mi) through the Pyrenees, descending 1,100 metres (3,600 ft) to the village of Peyrat, where it reaches a piedmont plain. Its valley widens as it traverses the plain, reaching the medieval city of Mirepoix, which marks the start of its lower valley.

Several rivers flow into it:

• From the Pyrenees: the Lasset; the Fontaine de Fontestorbes; the Touyre
• From the piedmont plain and hills: the Blau and the Douctouyre;
• From the hills of Lauragais and Razès: the Ambronne and the Vixiège.

Departments and towns along its course are:

• Ariège: Prades, Bélesta, La Bastide-sur-l'Hers, Mirepoix, Mazères
• Aude: Comus, Chalabre
• Haute-Garonne: Calmont

Floods

The Hers is probably known as vif (intense or rapid in this context) because of its sometimes spectacular floods – that of 16 June 1289 having entirely destroyed Mirepoix. More recently, there have been:

• 23 June 1875: estimated flow rate of 1,500 cubic metres per second (53,000 cu ft/s) at Mazères;
• 6 February 1919: estimated flow rate of 600 to 800 cubic metres per second (21,000 to 28,000 cu ft/s) at Mazères;
• 19 May 1977: estimated flow rate of 1,070 cubic metres per second (38,000 cu ft/s) at Mazères;
• 16 January 1981: estimated flow rate of 1,100 cubic metres per second (39,000 cu ft/s) at Mazères;
• 11 June 2000: estimated flow rate of 500 cubic metres per second (18,000 cu ft/s) at Mazères;
• 24 January 2004: estimated flow rate of 500 cubic metres per second (18,000 cu ft/s) at Mazères.

[de] Hers-Vif

Der Hers-Vif (oder Grand Hers) ist ein Fluss in Frankreich, der in der Region Okzitanien verläuft. Der Beiname Vif („lebendig“) unterscheidet ihn vom Hers-Mort („Toter Hers“), einem Nebenfluss der Aude. Er entspringt in den Pyrenäen, nahe dem Col du Chioula, im Gemeindegebiet von Prades. Er entwässert zunächst in vielen Richtungsänderungen generell nach Nord bis Nordost durch das Pays d’Aillou und verlässt das Plateau durch die Schlucht Gorges de la Frau. In seinem Mittellauf umläuft er im Osten den Lac de Montbel, dreht dann auf Nordwest und mündet nach rund 135[2] Kilometern im Gemeindegebiet von Cintegabelle als rechter Nebenfluss in die Ariège. Der Hers-Vif durchquert auf seinem Weg die Départements Ariège, Aude und Haute-Garonne.
