Cubic metres per second
- River discharge is the volume of water flowing through a river channel. This is the total volume of water flowing through a channel at any given point and is measured in cubic metres per second (cumecs).

The units that are typically used to express discharge in streams or rivers include m 3 /s (cubic meters per second), ft 3 /s (cubic feet per second or cfs) and/or acre-feet per day. [2] A commonly applied methodology for measuring, and estimating, the discharge of a river is based on a simplified form of the continuity equation.

River discharge is the volume of water flowing through a river channel. This is the total volume of water flowing through a channel at any given point and is measured in cubic metres per second (cumecs).
Discharge is the volume of water moving down a stream or river per unit of time, commonly expressed in cubic feet per second or gallons per day. In general, river discharge is computed by multiplying the area of water in a channel cross section by the average velocity of the water in that cross section: discharge = area x velocity
Apr 19, 2023 · Discharge tells us about the amount of water flowing through a river. More specifically, discharge is defined as the volume of water that flows through some cross section of a river, per unit time. Think of it this way – velocity is a distance per unit time, and discharge is a volume per unit time.
Mar 3, 2019 · Discharge Measurement. Streamflow, or discharge, is the volume of water moving down a stream or river per unit of time, commonly expressed in cubic feet per second or gallons per day.
Mar 30, 2023 · Generally, discharge Q (ft 3 /s or m 3 /s) is calculated as the velocity v (ft/s or m/s) of water moving through a unit area A (ft 2 or m 2): Q = v * A. Measures of discharge can range widely depending on the size and location of the stream as well as groundwater levels and recent precipitation.
The 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.
