in general, how do the channel width, channel depth, flow velocity, and discharge change between the headwaters and the mouth of the stream?

The Channel width, Channel depth, Flow velocity and discharge all increase as the stream approaches the mouth.What is the mouth of the stream called?The mouth, or delta, of a river, marks its terminus. The water slows down and spreads out into a fan shape near a river's delta as the ground flattens out. This typically occurs as a river empties into an ocean, lake, or marsh.What is Flow velocity?A fluid's flow velocity is its rate of movement, measured in metres per second or feet per minute. The flow velocity of a fluid can be impacted by friction along the pipe walls.The Channel width, channel depth, and velocity of the stream often rise along with the discharge. Position in the stream channel, abnormalities in the stream channel brought on by resistive rock, and stream gradient all affect a stream's velocity.Therefore, it increases as it reaches the mouth of the stream.To learn more about the Channel width from the given linkhttps://brainly.com/question/13259669#SPJ4
