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.

velocity like to power becaus velocity related to power.
There are three things a river's power to erode depends on that includes the slope of the river. The other two things are the volume of flow and the shape of its stream bed.
A wire from the power supply is carrying 120w of power and 24A of cu
P= F.v, where P is power, and F.v is the dot product of the Force and velocity vectors.

Why are power lines an extreme hazard when you are carrying or using an aluminium ladder?
No. The velocity ratio remains constant but the friction absorbs power.
