Water (estimated flow)Air (average) Rain (mm)Best months

From about 21 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.

The basin

Seman: the basin in numbers

6,123 km² of land send their water to this river. This is what lives on it.

Free-flowingDams upstream can hold only 0.0% of a year's flow: the river still keeps its natural rhythm.
