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.
The approximate minimum stream velocity needed to keep a particle in motion, such as a sphere with a diameter of 10 cm, can be estimated using Stokes' law and the concept of terminal velocity. For a particle in a fluid, the minimum velocity needed to keep it suspended typically equals the settling velocity, which depends on factors like fluid density and viscosity. In general, for a 10 cm diameter particle, the minimum velocity can range from about 0.1 to 0.5 meters per second, depending on the specific fluid properties.
Lots or aeronautic equations, but you'd need a whole lot more data than you have given.
Yes, the vertical drop of a stream channel over a certain distance is referred to as the stream's gradient or slope. It is calculated by measuring the change in elevation (vertical drop) divided by the horizontal distance over which this drop occurs. This gradient influences the stream's flow velocity and erosion potential, affecting the surrounding landscape and ecosystem. A steeper gradient typically results in faster flowing water and greater erosion.
assume river velocity = X mph boat velocity = 20 mph time to go 6 miles downstream = T1 time to go 3 miles upstream = T2 distance = time * velocity downstream: 6 mi = T1 * (boat velocity + river velocity) upstream: 3 mi = T2 * (boat velocity - river velocity) 6 = T1 * ( 20 + X ) 3 = T2 * ( 20 - X ) T1 * ( 20 + X ) = 2 * ( T2 * ( 20 - X ) ) since T1 = T2 then 20 + X = 40 - 2X 3X = 20 X = 6.67 thus, river velocity is 6.67mph
Deposition, whereby the sediment load being transported is dropped.
sand
Stream load refers to the amount of sediment and materials that are being transported by a stream. It can consist of sand, silt, gravel, and organic matter, and is influenced by factors such as stream velocity, discharge, and erosion within the watershed. Monitoring stream load is important for understanding sediment transport and its impact on water quality and ecosystems.
matter
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 carrying capacity of a stream refers to its ability to transport sediment. Higher discharge and velocity typically increase a stream's carrying capacity as they provide more energy to move sediment. However, if the stream's carrying capacity surpasses its available sediment, deposition can occur.
Sediment that is carried by a stream along the bottom of its channel.
A decrease in stream velocity due to factors such as a decrease in slope or widening of the stream channel can cause sediment to be deposited. When the stream's capacity to transport sediment is exceeded, it drops the sediment it was carrying. Additionally, changes in the stream's flow rate or turbulence levels can also result in sediment deposition.
The greater the time that stream sediment is transported, the greater the probability that the sediment will become more rounded and well-rounded due to abrasion and attrition processes.
