measure out ten feet of water, drop a rubber ducky, or some other floating object in the water. and then time it with a stopwatch ti see how long it takes to reach there. Then divide your data by ten to get the data in feet covered per second.
An increase in gradient will generally increase stream velocity.
A stream gauge is the instrument which is commonly used for the measurement of velocity stream.
The competence of a stream is determined by the stream's velocity and the size of the sediment it can transport. Streams with higher velocities and larger sediment sizes are typically more competent and can transport larger particles.
The higher the velocity of the stream the larger carrying capacity it has.
The gradient , the channel roughness, and the channel shape all effect the speed or velocity of stream flow
Speed and direction determine velocity
Stream discharge is a product of the velocity and the area of the stream (velocity x width x depth), and has units of volume per time (e.g. cubic feet per second, cubic meter per day, etc). Stream velocity is the vector describing the speed of the water and has units of length per time (feet per second, meter per second). Stream discharge is relatively constant as you move up and down a stream, while velocity will change predominately as you change depth. The velocity of water is lowest near the bed of the stream, and highest at the surface.
When a stream's discharge increases, erosive energy increases.
At what depth should a velocity sensor be placed to estimate a stream's average velocity if it is 12.5 meters deep?
In the middle, I think
