As water in the stream channel flows, it encounters friction; the friction slows the forward movement. The shape,size, and roughness affect the amount of friction. High friction slows the stream significantly.
Channel section is in shape of english alphabet "C"
There are three factors that affect stream erosion. These are water velocity, shape, size and depth of channel, and stream capacity to transport eroded materials.

water doesnt have a shape
Yes I think the shape of a boat will affect a foil boat because when you change the shape of a boat like when you make a triangle or a square it will affect the weight it can carry
It can affect the shape of sediment because it is scraping very slowly against it causing it to change,
None of these transformations affect the size nor shape of the image.
simplee yep
