Major river in Tunisia, the ancient Bagrada
At the mouth it carries 29 m³/s on average: an Olympic pool every 86 seconds. It drops from 692 m to -2 m, 1.5 m per kilometre on average. Its basin covers 22,500 km², about the size of BZ. 2.2 million people live in it. Highest water: from January to February; lowest: from June to September. It is heavily dammed: reservoirs can hold 57% of a year's flow.

Medjerda River, month by month
Highest water: from January to February
Lowest water: from June to September. Best months to visit: from April to June and from September to October.
From about 7.5 m³/s in the lowest month to 190 m³/s in the highest. An estimate: the monthly flow is modelled from the lowest and highest months of WaterGAP (RiverATLAS, 1971–2000) and the rain and snow along the river (WorldClim). Dams change the real rhythm. The chip is the average air temperature; below it, the month's rain.
