A stream discharge means the <u>quantity</u> of water flowing past a specific channel location per unit time.
<h3>What is a
stream discharge?</h3>
Basically, it refers to the volume of water that is passing a given point over a set time.
It also refers to the volume of water moving down a stream or river per unit of time which is commonly expressed in cubic feet per second or gallons per day.
In physics, the stream discharge is measured by using "discharge = area x velocity". Another method used for measuring the stream velocity is with a current meter. However, a variety of advanced equipment can also be used to sense stage and measure streamflow.
Therefore, the stream discharge means the quantity of water flowing past a specific channel location per unit time.
