Among the options given, **stream elevation** does not directly influence stream velocity in the same way that the other factors do.
- **Stream discharge** (the volume of water flowing per second) affects the velocity; more discharge generally increases velocity.
- **Stream gradient** (the slope of the stream) directly impacts velocity; steeper gradients usually lead to higher velocities.
- **Channel size** (the width and depth of the stream) also affects velocity; a larger channel can allow faster flow.
While elevation can affect other factors (like gradient), it is not a direct determinant of stream velocity like the others.
