The Aude (French pronunciation: [od] (listen); Occitan: [ˈawðe]; Latin Atax [ˈataks]) is a river of southern France that is 224 kilometres (139 mi) long.[1] Its source is in the Pyrenees mountains then runs to Carcassonne and finally reaches the Mediterranean Sea near Narbonne. The river is navigable by raft or canoe for nearly all of its length. It is registered as essential to the Languedoc-Roussillon region.

The river gave its name to the Aude department.


Etymology


In antiquity, the Aude was called Atax by the Romans.[4] Some authors in antiquity called the river Narbôn (e.g. Polybius).

In 1342 the Roussillon Cartulary of Alart called it the Auda or the Ribera d'Aude.[5] In the Middle Ages the terms Adice, again Atax, Fluvium Atacis, Flumine Atace, Flumen Ataze, and Juxta Aditum fluvium were also used to designate the Aude.[5] In all likelihood the current name comes from a gradual evolution of Atax given by Strabo (in his Geography, Book IV), a word borrowed from the Gallic term atacos meaning "spirited" or "very fast".[6]

Course

The river has its source in the Massif of Carlit at the Lac d'Aude at an elevation of 2,185 metres (7,169 ft) in the commune of Les Angles (department of Pyrénées-Orientales) and flows parallel to the Tet. The Col de la Quillane, elevation 1,713 metres (5,620 ft), marks the boundary of the watershed. The river then flows into the Mediterranean Sea a few kilometres from Narbonne at Grau de Vendres (near Cabanes-de-Fleury) on the border between the departments of Aude and Hérault.

At Carcassonne in the Pyrénées its course is oriented north-south. The Aude then presents the characteristics of a mountain stream as it traverses Capcir and feeds several reservoirs (Matemale, Puyvalador) before plunging into gorges (those of Saint-Georges are the most scenic) crossing ancient terrain. Starting from Axat, after being joined by the Aiguette on the right bank and the Rébenty on the left bank, the river flows through bands of pre-Pyrénéen limestone (in the Pierre-Lys Gorges) and passes through a series of small communes: Quillan, Espéraza, Couiza, Alet-les-Bains, then Limoux. Downstream of this great medieval city, the Aude flows eastwards. This elbow results from a Stream capture, the Aude having once flowed in the valley of the Hers, indicating a deepening by an ancient hydrology following the uplifting of the Pyrénées.[7]

From Carcassonne, the river becomes calmer following the great tectonic furrow which separates the Pyrénées (Corbières) from the Massif Central (Montagne Noire), receiving from these heights a series of tributaries of which the main ones are the Orbieu on the right bank, and the Argent-Double and the Casse on the left bank. From this point, bordered by the Canal du Midi and sinuous amid vineyards, the Aude enters the broad alluvial plain of Narbonne with the main stream flowing to the Gulf of Lion and some waters diverted to a network of ancient ponds before flowing into the Mediterranean Sea .

The Aude has a catchment area[8] of 6,074 square kilometres (2,345 sq mi) that extends unevenly across six departments: Aude, Pyrénées-Orientales, Ariège, Haute-Garonne, Tarn, and Hérault (Haute-Garonne and Tarn are only affected by the course of tributaries and sub-tributaries of the river). Before Carcassonne, the Aude receives tributary streams of short length which often have the characteristics of mountain torrents.

Starting from the prefecture of Aude department in the lower valley the Aude river joins with the largest rivers, most of them from the Montagne Noire. From upstream to downstream, the main tributaries of the Aude, longer than 10 km, are:[1]


Hydrology

In its upper reaches the Aude has a nivo-pluvial regime (with a maximum flow in spring linked to snowmelt). Then from Carcassonne[9] where the average flow rate reaches 20.4 cubic metres per second (720 cu ft/s), the system is almost entirely rainfed (The flow at Grau de Vendres[10] where it meets the Mediterranean is around 50 cubic metres per second (1,800 cu ft/s).)

The Aude is thus characterized in its lower course by a pluvio-nival regime of meridional type with high baseflow in summer, 9.8 cubic metres per second (350 cu ft/s) in August at Moussan[3] in the lower alluvial plain not far from the river mouth, against an average of 44.2 cubic metres per second (1,560 cu ft/s). Heavy autumnal rains enable a rapid rise in the flow rate which peaks in February, 78.6 cubic metres per second (2,780 cu ft/s) and is supported by the spring snowmelt from the Pyrénées mountains.


Floods of 1999


Exceptional and sudden rainfall, so characteristic of the Mediterranean climate during the autumnal season, can be the cause of devastating floods such as those of 12 and 13 November 1999. The results of this event, which affected the lower valley of the Aude, were catastrophic: 35 victims, hundreds of people evacuated by helicopter or rescued from thousands of homes, businesses, and commercial premises which were more or less damaged, 5,000 hectares (12,000 acres) of vineyards more or less ruined, roads, drinking water networks, and sanitation were seriously affected.[11] The scale of the disaster was due to the combination of two factors: Thunderstorms with rainfall on an unprecedented scale. Up to 620 millimetres (24 in) fell in two days at Lézignan-Corbières, that is to say more than the average annual total. In addition, a strong storm in the Gulf of Lyon led to a rise of 80 centimetres (31 in) in the sea level and, combined with the strong waves and wind, prevented the flow of water already swollen by the torrential rains.[11]


Floods of 2018


Remnants of Hurricane Leslie fed a quasi-stationary cold front over southwestern France, generating heavy thunderstorms and leading to flash flooding in that area.[12] The Aude rose to a height of 7 m (23 ft), its highest level since 1891.[13] Carcassonne received 160–180 mm (6.3–7.1 in) of rainfall within five hours; water level in the city rose 8 m (26 ft) during that period. At least 14 people died because of the flash flood, mainly in the town of Villegailhenc, Aude.
