What are the units for measuring discharge?

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). Depth times Width gives the cross-sectional area. The shape of the channel is important because of the reduction in velocity due to friction along the channel margins.

What is discharge geology?

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.

Which of the following may be used for measurement of discharge of water in rivers or streams?

Weirs may be used for measuring the rate of flow of water in rivers or streams.

Why do we measure discharge?

This is one reason for measuring flow – to work out the load of contaminants and sediment the waterway is carrying. Because discharge can have a significant effect on water quality, it is important that it is recorded at the time of sampling and, if possible, during the previous few days.

What is discharge river?

‘River discharge’ is the volume of water flowing through a river channel; measured at any given point in cubic metres per second.

What do you mean by discharge?

Why is measuring discharge important?

Because discharge can have a significant effect on water quality, it is important that it is recorded at the time of sampling and, if possible, during the previous few days. It is particularly valuable to know if flows are at low, moderate or high level and if the level is rising or falling.
