Detailed explanation-1: -Streamflow (also known as discharge) is the volume of water flowing past a given point in the stream in a given period of time. Streamflow is reported as cubic feet per second (ft3/s). Streamflow values are better indicators than gage height of conditions along the whole river.

Detailed explanation-2: -1 What is discharge? The discharge is the volume of water that is transported each second, and the volumes are expressed in litres (l) or in cubic metres (m3) [1 m3 = 1000 l], and the letter Q is commonly used as the symbol for the discharge.

Detailed explanation-3: -Steady and Unsteady Flow: E.g flow of water with constant discharge through a pipeline is as steady flow. The flow in which fluid characteristics like velocity, pressure, density etc. at a point changes with time is called as unsteady flow. E.g flow of water with varying discharge though a pipe is as unsteady flow.

Detailed explanation-4: -Discharge = V x D x W If length is measured in feet and time in seconds, Discharge has units of feet3/sec or cubic feet per second (cfs).

Detailed explanation-5: -Discharge is the volume of water that passes through a given cross section per unit time, usually measured in cubic feet per second (cfs) or cubic meters per second (cms). Stage is the level of the water surface over a datum (often sea level).
