What Controls the maximum size particle a stream can carry?
The maximum size particle a stream can carry is primarily controlled by the stream's velocity and discharge, which is the volume of water flowing per unit of time. Faster-moving water can transport larger and heavier particles due to increased kinetic energy. Additionally, the stream's gradient and channel shape can influence sediment transport, with steeper gradients typically facilitating the movement of larger particles. Lastly, the sediment's shape and density also play a role in determining its transport capacity.
What does the ability of a stream to erode and transport materials depend largely on?
The ability of a stream to erode and transport materials largely depends on its velocity and discharge. Higher flow velocity increases the stream's energy, allowing it to erode the riverbed and banks more effectively while transporting larger sediment particles. Additionally, the gradient of the streambed and the size, shape, and composition of the sediment also play significant roles in determining the stream's erosive and transport capacity.
What is the formula of mean particle size?
The formula for mean particle size is calculated by summing the individual particle sizes and dividing by the total number of particles. Mathematically, it is expressed as mean particle size = (Σ particle sizes) / total number of particles.
Are all the particles of sediment the same size?
No, sediment particles can vary in size from fine clay and silt to coarser sand and gravel. Sediment can contain a mixture of different particle sizes depending on the source and transport processes.
How big is a particle?
Particles can vary in size depending on the type of particle. For example, an atom is about one angstrom in size, while a typical virus particle can range from 20 to 400 nanometers. In contrast, a dust particle might be around 10 micrometers in size.

What is the largest size particle that a stream can carry?
The largest size particle that a stream can carry is typically referred to as the stream's competency limit. This limit is reached when the stream's velocity is no longer able to transport a particle of a certain size due to its weight and shape, causing the particle to be deposited on the streambed instead.
What is the minimum stream velocity needed to carry a particle of sand?
The minimum stream velocity needed to carry a particle of sand depends on the size and weight of the sand particle, as well as the characteristics of the stream such as flow rate and turbulence. In general, for typical sand particles, a stream velocity of around 0.3 m/s to 1 m/s is needed to entrain and transport them.
When stream flow decreases to below the critical settleing velocity of a certain size particle?
When stream flow decreases to below the critical settling velocity of a certain size particle, the particle will settle out of suspension and deposit on the streambed. This process is known as sediment deposition and is influenced by factors such as stream velocity, particle size, and sediment concentration.
What is the relationship between the particle size and wavelength?
IF and ONLY IF when the mass of particles are same. Large particle sizes will need high stream's velocity to carry it from one place to another,In another word If the stream velocity is slow than large particle sizes will be stationary.
What is the approximate minimum stream velocity needed to move a particle with a diameter of a 6.4 moving?
The approximate minimum stream velocity needed to move a particle with a diameter of 6.4 can be determined using the equation for the critical velocity of sediment transport. For a particle of this size, the critical velocity is typically around 0.3-0.4 m/s in most natural streams and rivers.
What stream characteristic is measured by the size of the largest particle that a stream can move?
The measure of the largest particles a stream can carry is capacity.
What occurs when stream flow decreases to below the critical setting velocity of a certain size particle?
When stream flow decreases below the critical settling velocity of a certain size particle, the particle will settle out of the flow and deposit on the streambed. This process is known as sedimentation and can lead to the formation of sediment layers along the stream channel. Over time, these deposits can alter the shape and depth of the stream channel.
What is the maximum size of a clay particle?
The maximum size of a clay particle is around 0.002 millimeters or 2 micrometers. Clay particles are some of the smallest soil particles, much smaller than silt or sand particles.
How do particle size and density affect the look of dry stream beds?
the deepest will be at the very bottom
What factor determines the competence of a stream?
The competence of a stream is determined by the stream's velocity and the size of the sediment it can transport. Streams with higher velocities and larger sediment sizes are typically more competent and can transport larger particles.
The capacity of a stream measures the maximum size of particles it is capable of transporting?
FALSE
