Why does the occupied channel width increase as you get further downstream?

This happens because in the lower course of the river, where the channel is much closer to base level, there is much more lateral erosion taking place and a lot less vertical. In the upper course, more vertical erosion takes place because the river is cutting down in an attempt to reach base level. As the river is reaching its mouth in the lower course, less vertical erosion is needed. Also because the river has a greater velocity downstream, due to more water entering the river from tributaries, there is more kinetic energy for lateral erosion to take place. This leads to more erosion in the form of abrasion, hydraulic action and cavitation which will widen the river channel.

Does the volume of water in a river increase further downstream?
yes
Will agricultural land use increase as you mover downstream Mae Sa river?
In a typical river, yes. But in the MAe Sa, the crops and agriculture is better further upstream.
WHAT London bridge is the furthest downstream?
Tower Bridge The QE2 bridge at Dartford, where the M25 crosses the Thames is the furthest bridge downstream. There is also a tunnel here, used by traffic going in the opposite direction. The absolute last crossing is a few Km further downstream. It is the rail tunnel on the High Speed line from St. Pancras to the Channel Tunnel.
What is backwater flooding?
Backwater flooding happens when there is an obstruction downstream that causes the water further upstream to rise over the banks and into the landscape. An ice jam or channel restriction can cause backwater flooding.
Why does a stream discharge increase?
In the upper course of a river, there is a V-shaped valley with a steep gradient as the water is constantly using up the majority of its energy to overcome friction. As a river flows downstream, the valley becomes a U-shape and the gradient decreases. This is because there is less gravitational pull towards the sea/lake level. Also towards the middle and lower courses, there are more tributaries and confluences which will add more discharge to the river basin. This is constantly happening and thus, as it flows downstream it increases. The velocity also increases as there is more discharge.
The average sediment size decreases downstream?
As the rocks collide together they get smaller, so then the smaller ones are deposited further downstream, this is known as attrition.
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.
What are some synonyms of the word 'occupied'?
The word 'occupied' means closed for business, closed until further notice, not available or busy with something. The term 'occupied' can thus be used with several meanings.
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.
What is is called when a river in its middle course splits up into two or more smaller channels which rejoin further downstream?
tributry
What does occupied japan mean?
"Occupied" means that the country, Japan in this case, has soldiers stationed there after their defeat, in this case, the United States, to keep the peace and prevent further warlike activities.
What is the river thames width?
The river Thames increases in width the further downstream you go. See related link...
