The bar is a river in France that runs in the Ardennes department in the Grand Est region .

geography

course

The bar rises at an altitude of 170  m in the municipality of Harricourt , generally drains north to northwest and finally flows into the municipality of Villers-sur-Bar , near Sedan , as a left tributary after about 62 kilometers at an altitude of about 145  m the canalized Meuse , which here forms the Canal de la Meuse .

The Canal des Ardennes

Its course ends around 35 meters below its source, so it has a mean bottom gradient of around 0.41 ‰.

In its lower reaches, the bar is accompanied by the Canal des Ardennes as a side canal and also used for its water supply.

Hydrology

At the confluence with the Meuse, the mean flow rate (MQ) is 5.60 m³ / s; the catchment area here covers 424.9 km².

In Cheveuges, the average annual runoff from the bar was calculated over a period of 50 years (1970–2019) . The catchment area at this point corresponds to about 389 km², about 91.6% of the total catchment area of ​​the bar.

The flow rate of the bar , with the annual average of 5.21 m³ / s, fluctuates strongly over the course of the year. The highest water levels are measured in the winter months from December to March. The flow rate reached its peak at 10.50 m³ / s in the two months of January and February. From April onwards the discharge decreases month by month and reaches its lowest level in September with 1.31 m³ / s, after which it increases again from month to month.

The monthly mean runoff (MQ) of the bar in m³ / s, measured at the Cheveuges hydrological station.
