What is the relationship between the particle size and wavelength?

IF and ONLY IF when the mass of particles are same. Large particle sizes will need high stream's velocity to carry it from one place to another,In another word If the stream velocity is slow than large particle sizes will be stationary.


Why is stream velocity important to the carrying power of a stream?

As a particle size gets larger in a stream, the force needed to move the particle in the suspended water column is greater. The velocity dictates which size particles are able to be picked up from the bed and carried as stream load. Some particles, such as fine silts, require very little velocity and can be dissolved on their own without moving water. Larger, coarse rock particles may require extremely high velocities which may only be reached during storm events, depending on the stream of course.

What is the difference between stream discharge and stream 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.
