A stream with a velocity of 20 cm/s can transport particles up to fine sand size (0.0625 - 2 mm). Larger particles such as gravel and boulders would require a faster flow velocity to be transported.
To prevent particles of 0.01 cm from settling downstream, a minimum stream velocity of 0.02 m/s is required, based on Stokes' law calculations for settling velocity.
Stream velocity has a direct impact on the size of sediments that can be transported. Higher stream velocities can carry larger and heavier sediments due to increased erosive forces, while slower velocities are limited to transporting smaller and lighter sediments. This relationship is known as Hjulstrom's curve.
A logarithmic graph would best represent the relationship between stream velocity and the size of particles it can carry downstream. As velocity increases, the stream can carry larger particles due to increased erosion and transport capacity. However, there will be a limit to the size of particles carried downstream as velocity continues to increase.
The settling rate of the sand particles and the flow velocity of the stream are the two main factors that determine when the sand will settle out of the stream. Higher settling rates and lower flow velocities typically lead to quicker settling of the sand particles.
larger particles settle to the bottom first as the velocity of the stream increases. This is because larger particles have more inertia and are less affected by the drag force of the flowing water, allowing them to settle faster than smaller particles.
The measure of the largest particles that a stream can carry is typically determined by its stream power, bed material size, and flow velocity. Streams with higher stream power and flow velocity are able to transport larger particles. The largest particles a stream can carry before they settle to the streambed are usually referred to as the stream's "bedload" particles.

An example of a sediment found along a stream is sand. Sand particles are typically larger than silt or clay and are commonly found in streambeds or along the banks of rivers and streams. They are transported by the flowing water and deposited when the flow velocity decreases.

The answer is cobble.
As a particle size gets larger in a stream, the force needed to move the particle in the suspended water column is greater. The velocity dictates which size particles are able to be picked up from the bed and carried as stream load. Some particles, such as fine silts, require very little velocity and can be dissolved on their own without moving water. Larger, coarse rock particles may require extremely high velocities which may only be reached during storm events, depending on the stream of course.
The particles bouncing along a stream bottom is called saltation. This process involves particles being lifted and transported by the flow of water, before being dropped or settling back to the stream bottom. Saltation is common in streams with moderate flow velocities and bed roughness.
