Answer to Question 1

In order to accommodate the growing discharge, channel size increases downstream. With an increased channel size and discharge, there is also an increased flow velocity. Thus, flow velocity tends to be greater at the mouth of a stream.

Answer to Question 2

As dissolved load within the water, as suspended load held in the water column, and as bed load along the streambed. Bed load moves only intermittently, bouncing along the base of the stream, so it moves the slowest.
