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.

Which groups of particles sizes can be transported by a stream that has a velocity equal to 20 cms?
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.
What is the relationship between the carrying capacity of a stream and it's discharge and velocity?
The carrying capacity of a stream is influenced by its discharge and velocity. A higher discharge and velocity typically allow a stream to transport larger sediments and materials downstream, increasing its carrying capacity. Conversely, lower discharge and velocity may limit the stream's ability to carry sediment and materials.
How does a streams gradient affect of velocity?
A steeper stream gradient usually leads to faster stream velocity because the force of gravity pulling the water downhill is greater, causing the water to flow more quickly. Conversely, a gentler gradient results in slower stream velocity as there is less force pulling the water downhill.
How does a stream's gradient affect in velocity?
A steeper gradient generally results in a faster flow velocity, while a shallower gradient typically leads to slower flow velocity in a stream. This is because the slope of the streambed determines how quickly water can move downstream due to gravity.
What is the definition of stream load?
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.
Which change at a particular location in a stream usually causes more sediments to be deposited at a location?
A decrease in water velocity usually causes more sediments to be deposited at a location in a stream. This can happen when the stream widens, the channel gradient decreases, or obstacles such as rocks or vegetation slow down the flow of water.
How does the velocity of the stream affect erosion?
Higher velocity of the stream increases erosion by carrying and transporting more sediments, which can wear away the streambed and banks more quickly. It also increases the force of the water, allowing it to break down and transport larger rocks and debris. Conversely, lower velocity streams erode more slowly.
What can a stream flowing at a velocity of 100 cm sec can transport?
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.
Which groups of particles sizes can be transported by a stream that has a velocity equal to 20 cms?
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.
When the velocity of a stream suddenly decreases the sediment being transported undergoes an increase in?
Deposition, whereby the sediment load being transported is dropped.
What is the relationship between the carrying capacity of a stream and it's discharge and velocity?
The carrying capacity of a stream is influenced by its discharge and velocity. A higher discharge and velocity typically allow a stream to transport larger sediments and materials downstream, increasing its carrying capacity. Conversely, lower discharge and velocity may limit the stream's ability to carry sediment and materials.
When sediments is transported down a mountain and along a streare you are seeing the conservation of?
When sediments are transported down a mountain and along a stream, you are witnessing the conservation of mass, energy, and momentum. The sediments are being carried by the flowing water while maintaining their total quantity and energy throughout the journey. This illustrates the principle of conservation in natural systems.
How does velocity affect a stream of water?
It cuts a wider, shallow channel .
How does a stream carry materials?
A stream carries materials through a process called erosion, where water and sediments are transported downstream. The flow of water in a stream can dislodge and carry rocks, soil, and other debris, along with any pollutants present, to be deposited in another location. The speed and volume of water in a stream can impact how much material it can carry.
How are the ionic or dissolved sediments carried in a stream released?
Sediments are carried as the following loads: dissolved, suspended, and bed. A dissolved load is composed of ions in solution. These ions are usually carried in the water all the way to the ocean. ... Particles that are too large to be carried as suspended loads are bumped and pushed along the stream bed, called bed load.
The ability of a stream to erode and transport material depends largely on what?
The ability of a stream to erode and transport material largely depends on its discharge, velocity, gradient, and the size and shape of the sediments. These factors influence how much sediment a stream can carry and how effectively it can erode material from its surroundings.
How does an increase in a streams velocity affect its discharge and carrying capacity?
When the discharge of a stream increases, so does it's velocity. When it decreases, so does the velocity.
