The channel roughness decreases because the water and little parts of rock in it will start to slowly smooth the surface under the water.

Does gradient of a stream increase or decrease downstream?
Decrease. The source of the river is usually in a mountainous area with a steep gradient.
Why does load particles decrease downstream?
Fine silt and mud are carried further downstream than heavier rocks and gravel. Which often results in muddy banks at the river mouth.
Why does the gradient of a river decrease downstream direction?
It doesn't decrease, it increases. It only apears to decrease because the lower course of a river is smoother. Because of waterfalls etc in the upper course, it appears to be going quicker when actually obstructions, although creating a splash, decrease spped.
Is the mouth of the Nile River upstream or downstream from its source?
Downstream. The source of a river is always upstream.
What is the downstream portion of a river?
the mouth of the river.?
When a capsized and floating on your back in a swift river current how should you position your feet?
You should position your feet facing downstream if you have capsized and are floating on your back in a swift river current.
Does a stream's velocity increase or decrease downstream?
increase
Does a river flow from upstream to downstream?
No, a river only flows one way, they either flow upstream or downstream not both.
Why does volume of load decrease as you go downstream?
erosion :P
Does river load size decrease?
The size of the pebble will decrease down stream because the further downstream you go the quicker the river velocity. This means there will be more abrasion against the sides and bed of the river and the friction will be greater, this wears away the river load making it decrease in size. Increase velocity means that bigger material will be picked up by the river and carried as river load. More load in the river and increased size of load will mean more attrition and the river load will keep colliding into each other smoothening and rounding their shape. Brap brap !!
When you are traveling downstream on a river you are going with the flow of the river or against?
You are going with the flow of the river
How does turbulence affect the speed of a river?
it slows the streams flow
