Speed and direction determine velocity

Three factors are most important in determining the average velocity of a stream. One factor is the GRADIENT,or slope of the stream.Another factor is the DISCHARGE,or volume of water in the stream.Generally,as either the slope or the discharge of a stream increases,the velocity increases. The third factor involved is the STREAM CHANNEL SHAPE,the shape of the bed of rock or loose materials that confine the stream.

it is an instrument to determine the velocity of flow at required point in a flowing stream.

An increase in gradient will generally increase stream velocity.

one factor is multiply accelaration per time

The higher the velocity of the stream the larger carrying capacity it has.

what is the relationship between particle size and the stream velocity?

describe the relationship between stream velocity,erosion,transport and deposition

You need to have displacement and time for you to determine the velocity.

One of the factors that determine force of impact is the object's mass. Another factor that will determine the force of impact is the object's 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.

Stream velocity is dependent of four things. They are, the flow type, the gradient, the channel shape, and the discharge of the stream. Streams will flow faster in narrow channels on steeper grades.

If in a given stream the velocity doubles, the discharge: Choose one answer

The velocity of the water in a stream increases when the stream gets narrower or shallower (or both).

The higher the velocity, the higher the erosive power.

the competence and capacity of a steam depend on a streams velocity and discharge. Because the velocity and discharge of a given stream are not constant , the competence and capacity of a stream are not constant . competence and capacity vary along a stream and change throughout the year.

Stream load is when solid matter is carried by a stream. Stream capacity depends on the velocity, the amount of water flow and the grade.

rate of stream discharge is directly proportional to the erosion i.e the higher the velocity of the stream then it will erode the rock rapidly while the deposition process will be slow when the velocity will be high.

You would need to sample the velocity at at least two different points of time in order to determine how to velocity is changing. This is because velocity is the first order integral of acceleration, making acceleration the first order differential of velocity. Distance does not really enter into the equation as that is a second order factor, except that you can use distance traveled from one time to the next to estimate velocity

Speed and direction determine an object's velocity.

When the discharge of a stream increases, so does it's velocity. When it decreases, so does the velocity.

Stream discharge physically depends on two factors: stream cross-sectional area and velocity. Area is composed of width and depth. Q (flow) = vel x width x depth. Stream elevation change, or how steep a stream is, will affect the velocity. Higher sloping streams (like those with few meanders) will travel faster than sinuous, snaking streams that have a lower elevation drop per length of stream.
