Does the river velocity increase or decrease as you go downstream?

in relation to the flow dynamics of the water against standing water(resistance) and the widening if the river in relation to flow (expanding area in relation to pressure) it would be easy to see that the flow can diminish. what factors need to be taken into account is changes in the elevation of the flow ( decreasing elevation would obviously increase the flow and elevated areas would widen the river and create lakes) this can be seen by rapids and pooling in the river. so velocity would be a variable but the gallon per minute flow would be more of a constant
please let me know if this helps you

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 the velocity of the river increases downstream?
It won't increase BECAUSE it goes downstream. Rather, the speed of the river depends on other factors, such as how narrow the riverbed is, or on the slope.
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 !!
Why does river velocity increase downstream?
Velocity increases in a downstream direction because more sources of water combine depth and width. A constant flow of water would result in a higher river velocity.
Does the volume of water in a river increase further downstream?
yes
How does the gradient of a river affect its flow?
The gradient of a river is mostly flat or downhill which means that as the water flows it is affected by gravity. The steeper the gradient goes downhill, the more gravity will affect the water which will make the water flow faster (increases the velocity).
The explaination of the Bradshaw model?
The Bradshaw model is a geographical model made in 1978, by Proffesor Michel Bradshaw, which describes how a river's characteristics vary between the upper course and lower course of a river. It shows that channel width, channel depth and the wetted perimeter increase downstream. The Bradshaw Model shows how certain elements of a river increase in size or amount in their journey downstream, while some decrease such as the load particle size.
Why does the float time of a river increase or decrease?
hi there the reason for this is if you are mesuring the float time near the source of the river then it will take longer because the river needs to build up velocity as the river travels down steam is you take you data near the mouth of the river that float time will be shorter because the river velocity will have increased in speed i hope i helped out.
If a boat can go 20 miles per hours in still water and can go six miles downstream and 3 miles up stream in the same time how fast is the river?
assume river velocity = X mph boat velocity = 20 mph time to go 6 miles downstream = T1 time to go 3 miles upstream = T2 distance = time * velocity downstream: 6 mi = T1 * (boat velocity + river velocity) upstream: 3 mi = T2 * (boat velocity - river velocity) 6 = T1 * ( 20 + X ) 3 = T2 * ( 20 - X ) T1 * ( 20 + X ) = 2 * ( T2 * ( 20 - X ) ) since T1 = T2 then 20 + X = 40 - 2X 3X = 20 X = 6.67 thus, river velocity is 6.67mph
Why does the volume of the river increase downstream?
A river increases in volume as more streams join the main flow in the lower reaches.
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.
Did steamboats make business in river cities increase or decrease?
increase business
