For a given mass of stream water, its kinetic energy is proportional to the speed of flow squared. So, for example, if we double the speed of the stream its kinetic energy will increase by four fold. And kinetic energy can be found from the average force acting on some mass (e.g., those "particles") over a distance.
So one can conclude that a faster moving stream can exert more force on the stones and debris in that stream. Which means the faster moving stream is more likely to be able to actually lift and carry larger heavier particles than the slower stream can. NOTE: This discounts particles that can float in a static stream, like wood chips, as they are carried without the stream flowing.

The velocity of a settling grain in a fluid is controlled by a number of factors including the density of the particle, the density of the fluid, the fluid viscosity and the particles radius. This is derived from "Stokes' Law" - See the related link.
The terminal velocity (Vs) can be found using the following equation:
VS = (2 x r2(DP - DF)g) / (9 x VF)
Where:
r = Particle radius (m)
DP = Particle density (kgm-3)
DF = Fluid density (kgm-3)
g = Gravitational acceleration (ms-2)
VF = Fluid viscosity (Pa S)
From the above it should be clear that as the radius of the particle increases, the velocity at which it sinks will significantly increase (due to the square term).
Please see the related links for more information.

What factors affect a river's ability to erode and carry sediment?
The factors that affect a river's ability to erode and carry sediment would be its size, how deep it is, and how fast it is going. If it is going downhill that can also affect it.
Moving water in a river can pick up sediment and carry it along in a what kind of load?
bed load, a large load
What is deposition of sediment outside the banks of a river?
Sediment
What is the total quantity of sediment carried by a river called?
sediment load
Do the levels and the sediment load increase or decrease as the river ages?
As a river gets older sediment load decreases due to the age of the river and erosion
The smaller the load a river has the more sediment it can carry?
The smaller the load a river has the more sediment it can carry is false. When the river has more energy, it is able to carry a larger load, therefore more sediment.
Can the smaller the load a river has the more sediment it can carry?
The smaller the load a river has the more sediment it can carry is false. When the river has more energy, it is able to carry a larger load, therefore more sediment.
How many tons of sediment does the river thames carry in a year?
30,000
Does the smaller the load a river has the more sediment it can carry?
True or false?
What is the relationship between velocity sediment size and river size?
As the steam velocity increases, the diameter of the sediments being transported increases.
How do a river slope and volume of affect the river sediment load?
The steeper the slope, the faster the water will run, and the more sediment it can carry.The larger the volume of water that is moving, the more sediment it can carry with it.
How do a river slope and volume of flow affect the river sediment load?
The steeper the slope, the faster the water will run, and the more sediment it can carry.The larger the volume of water that is moving, the more sediment it can carry with it.
How do river's slope and volume of flow affect the river's sediment load.?
The steeper the slope, the faster the water will run, and the more sediment it can carry.The larger the volume of water that is moving, the more sediment it can carry with it.

What does the Nile River carry with it as it rushes northward?
Apart from fish and amphibians, sediment.
What does the nile river carry with it as it rushes north?
dirt and sediment, billions of tons.
What factors affect a river's ability to erode and carry sediment?
The factors that affect a river's ability to erode and carry sediment would be its size, how deep it is, and how fast it is going. If it is going downhill that can also affect it.
