In a stream, heavy sediments settle quickly and finer sediments stay suspended in the water and get carried down stream farther, even as the stream shrinks in size.
A stream flowing at a velocity of 100 cm/sec can transport a variety of materials, including sediments, organic matter, and debris. The capacity to carry these loads depends on the stream's flow rate, depth, and the size and density of the transported materials. Larger and heavier particles may settle to the bottom, while finer sediments can be suspended in the water column. Overall, faster streams can carry more substantial loads compared to slower ones.
500 km = 50 x 106 cm.50 x 106 cm / 2.5 cmyr-1 = 20 x 106 years or twenty million years.If it takes 1000 years to form 1 cm of sediment, then the thickness of the sediment in cm is:20x106 / 1x103Thickness of sediment = 20,000 cm or 200m.
pebbles are sediments that range in size from 0.2 cm to 6.4 cm.
The largest sediment that can be transported by a stream is determined by the stream's velocity and the sediment's size and weight. Generally, a stream with a velocity of 125 cm per second can transport larger particles, such as gravel or small boulders, depending on factors like flow turbulence and sediment density. However, specific calculations using the Einstein-Brown equation or other sediment transport formulas can provide a more precise size estimate. Typically, at this velocity, the largest sediment might be around 2 to 4 millimeters in diameter.
Sediments of 0.0002 cm in diameter would likely form siltstone, a type of sedimentary rock composed primarily of silt-sized particles. Siltstone has a fine-grained texture, as silt particles are smaller than sand but larger than clay.
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.
hey....
Which dimensions are which? For a base of 2 cm, height of 3 cm, and length of 2 cm it would be 5 cm^3. It would be the same if the base were 3 cm, but if the length were 3 cm it would instead be 6 cm^3.
Given the category and the fact that 'rio' means - river / brook / stream. The answer to your question is that a river does not have a 'height'.
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.
The minimum stream velocity needed to keep a 6.4 cm diameter particle in motion is dependent on factors such as the density of the particle and the fluid, as well as other environmental conditions. However, as a general guideline, the velocity required can be estimated to be around 2-3 cm/s for particles of this size.
It would be about 3.35 cm
