Why does the size of bed load decrease downstream?
The size of bed load decreases downstream due to the processes of abrasion and hydraulic sorting. As sediment is transported by the river's flow, larger particles collide with each other and with the riverbed, leading to fragmentation and size reduction. Additionally, the river's velocity typically decreases downstream, allowing smaller particles to remain suspended while larger ones settle out. This results in a gradual decrease in the size of the bed load as it moves downstream.
Why does volume of load decrease as you go downstream?
erosion :P
Why does load particle size decrease downstream?
Load particle size decreases downstream due to the transport capacity of the river being higher further downstream, allowing larger particles to settle out and be deposited. Smaller particles are able to remain in suspension and be carried further downstream before settling. Additionally, erosion and weathering of larger particles can lead to their breakdown into smaller particles over time.
What is the difference between a streams suspended load and its bed load?
The difference between a suspended load and a bead load is a suspended load consists of the small particles or rock materials that are dispersed throughout the water and easily carried downstream. The bead load consists of the larger particles that are dragged and bounced along near the bottom of the river.
What is the difference between a river's suspended load and its bed load?

What and the difference between a rivers suspended load and it and bed load?
The difference between a suspended load and a bead load is a suspended load consists of the small particles or rock materials that are dispersed throughout the water and easily carried downstream. The bead load consists of the larger particles that are dragged and bounced along near the bottom of the river.

What is the difference between a rivers suspended load and it's bed load?
The difference between a suspended load and a bead load is a suspended load consists of the small particles or rock materials that are dispersed throughout the water and easily carried downstream. The bead load consists of the larger particles that are dragged and bounced along near the bottom of the river.
What is the difference between suspended load and bed load?
Suspended load refers to sediment particles carried in the water column, while bed load refers to sediment particles that are transported along the riverbed through rolling, sliding, or saltating movements. Suspended load is typically finer particles that remain suspended in the water, while bed load is larger particles that move along the riverbed.
Why does load vary downstream?
This is the amount of load a river can carry. Generally, the load quantity will increase with discharge and velocity because rivers of higher discharge and velocity have more energy so will be able to carry more load. Therefore, load quantity increases downstream. Also, small particles require less energy to be carried so as the load size decreases, quantity increases
How do stream transport sediments?
Stream transport sediment in three ways, dissolved load, (ions in solution being carried downstream), suspended load, (suspended sediment that floats freely downstream) and bed load, (sediment that rolls or scoots along the bottom of the river).
What decreases downstream along the length of the stream?
Downstream along the length of a stream, several factors typically decrease, including water velocity, as friction with the streambed increases and the channel widens. Additionally, the concentration of dissolved oxygen often diminishes due to higher temperatures and the decomposition of organic matter. Sediment load may also decrease as larger particles settle out in slower-moving sections. Lastly, biodiversity can decline in some areas due to pollution or habitat alteration.
