Basic
Stream Discharge
Volume of water flowing past a point per unit time.
Formula
Variables
QDischarge (m³/s)
ACross-sectional area (m²)
vAverage velocity (m/s)
Example
A=20 m², v=1.5 m/s → Q = 30 m³/s
Did You Know?
The Amazon discharges about 209,000 m³/s — roughly a fifth of all river flow on Earth.
