what is bed load particle size
the gradient of the slope The channel roughness The amount and size of bed load
The amount of sediments a river can carry is influenced by factors such as the river's velocity, volume of water, slope of the river bed, sediment particle size, and the presence of vegetation or structures that can trap sediments. Increased velocity and water volume typically result in higher sediment transport capacity.
The velocity and discharge volume of the stream or river.
The bedload becomes smaller when the river is flowing downstream, and the rocks also become smaller, smoother and rounder due to attrition and abrasion. (The reason the flow slows down is because the energy of the flow decreases.)
Bed Load
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.
Yes, it is. It means of larger than nominal size (oversized load, oversized bed).
The suspended load moves with the water, the bed load only moves when the river is in spate.
bed load. This type of stream load consists of heavier materials that are transported along the stream bed through rolling, sliding, or bouncing. It tends to move more slowly than suspended load or dissolved load.

When stream flow decreases below the critical settling velocity of a certain size particle, the particle will settle out of the water column and deposit on the bed of the channel or river. This process is known as sediment deposition and can contribute to changes in channel morphology and habitat.
