WebThe discharge of a river (or stream) is the volume of water that streams past a point in the river’s course every second. The volume is estimated in cubic meters (m 3 ), and it is every second, so the units of discharge are cubic meters a second or m 3 s -1. Unintentionally, 1m 3 s -1 is equivalent to 1 cumec, so the discharge of a river is ...
