Which of the following is a measure of a stream’s ability to transport?
Capacity is the maximum load of solid particles a stream can transport per unit of time, whereas competence is a measure of a stream's ability to transport particles based on size rather than quantity.
What factor determines the largest particle A stream can transport?
The greater the discharge the greater the capacity. CM– the maximum particle size a stream can transport. Streams with faster velocity have higher competence.
Which of the following correctly describes a streams capacity?
Which of the following correctly describes a stream's capacity? It is the potential load a stream can transport.
Which part of the load transported by streams contains boulders?
In a suspended load, where streams carry the largest part of their load, usually is made up of fine sand, silt, and clay, but larger particles may be transported during flood stage. In a bed load, coarse materials including course sands, gravels, and boulders move along the bed load by rolling, sliding, or saltation.
How is stream capacity measured?
It is calculated as Q = V * A, where V is the stream velocity and A is the stream's cross-sectional area. Units of discharge are volume per time (e.g., m3/sec or million gallons per day, mgpd).
What is discharge a measurement of?
discharge = area x velocity The most common method used by the USGS for measuring velocity is with a current meter. However, a variety of advanced equipment can also be used to sense stage and measure streamflow. In the simplest method, a current meter turns with the flow of the river or stream.
What is stream transportation?
Stream Transportation Large particles rest on the bottom, typically anything larger than sand, is called bedload , and may only be moved during rapid flows under flood conditions. They can be moved by saltation (bouncing) and by traction (being pushed along by the force of the flow).
What term describes the total sediment load transported by a stream?
The maximum load of sediment that a stream can transport is called its capacity. Capacity is directly proportional to the discharge: the greater the amount of water flowing in the stream the greater the amount of sediment it can carry.
What is the end of a stream called?
mouth The top end of a stream, where its flow begins, is its source. The bottom end is its mouth. In between, the stream flows through its main course or trunk.
Which particles will be transported by a stream?
Streams carry dissolved ions as dissolved load, fine clay and silt particles as suspended load, and coarse sands and gravels as bed load. Fine particles will only remain suspended if flow is turbulent.
In what ways does a stream transport its load?
The three ways that the stream transports its load is in solution/dissolved load, suspension/suspended load, and sliding or rolling along the bottom/bed load.
How do you measure stream width?
Determine the width of each transect by measuring the distance from shoreline to shoreline. Simply add together all the interval widths for each transect to determine its width. In the Figure 5.6 example, the width of Transect #1 is 8 feet and the width of Transect #2 is 10 feet.
What is stream flow measurement?
Most streamflow (discharge) measurements use a technique where the cross-section of the stream is "cut" into subsections. Depth, width, and velocity are measured in each section to calculate the volume of streamflow (discharge). The streamflows in all sections are then added up to get the total for the stream.
How is stream discharge measured?
Using the depth and width measurements for calculating the area and the velocity measurements, the discharge is computed by the ADCP using discharge = area x velocity, similar to the conventional current-meter method.
How is stream load transported?
Stream competence is the largest size material the stream can move under a given discharge. Bed load is that which is moved across the bed of the channel. Bed load is transported in two ways, traction, which is a scooting and rolling of particles along the bed. The second is saltation, a bouncing-like movement.
What term describes the particle transport mode that is intermediate between suspension and rolling?
Hydrologic cycle. What term describes the particle transport mode that is intermediate between suspension and rolling along the bottom of streams? This process also moves sand grains in a sand dune. Saltation.
What is capacity in geology?
The capacity of a stream or river is the total amount of sediment a stream is able to transport. This measurement usually corresponds to the stream power and the width-integrated bed shear stress across section along a stream profile.
What is stream name?
A stream name is a string that optionally includes an ID that is prefixed by a dash (-) character, and may also include category types that indicate even further specialized uses of the stream.
What do you mean by stream?
Definition of stream (Entry 1 of 2) 1 : a body of running water (such as a river or creek) flowing on the earth also : any body of flowing fluid (such as water or gas) 2a : a steady succession (as of words or events) kept up an endless stream of chatter. b : a constantly renewed or steady supply a stream of revenue.
How do stream transport sediments?
Most of the sediment transport occurs in high flow conditions. Sediment load is the solid material carried by water and transported through saltation (bouncing), traction (rolling and dragging) and suspension (carrying in water).
How do you measure flow?
A pitot tube is used to measure fluid flow velocity. The tube is pointed into the flow and the difference between the stagnation pressure at the tip of the probe and the static pressure at its side is measured, yielding the dynamic pressure from which the fluid velocity is calculated using Bernoulli's equation.
Why do we measure stream flow?
Streamflow information is required to determine how much water is available in different locations so the citizens can make informed decisions about growth and to help assure there is an adequate water supply even during periods of drought.
What is Venturimeter used for?
Venturimeter is a device used to measure the rate of flow of fluid flowing through a pipe. Venturimeter is a device which is used for measuring the rate of flow of fluid flowing through a pipe.
What is a water flow gauge?
A water flow meter is a device that measures the amount of water flowing through a pipe. There are several water flow meter technologies to choose from depending on the water measurement application, maintenance requirements, and budgetary terms.
What term describes the particle transport mode?
Hydrologic cycle. What term describes the particle transport mode that is intermediate between suspension and rolling along the bottom of streams? This process also moves sand grains in a sand dune. Saltation.
What is the carrying capacity of a stream?
Literally, the carrying capacity of a stream is the amount of sediment it can transport under the given flow conditions. This is generally a descriptive term not used for quantitative statements of rates and amounts of sediment discharge, and its use is generally discouraged.
What is in a stream?
A stream is a body of water that flows on Earth's surface. The word stream is often used interchangeably with river, though rivers usually describe larger streams.
What is stream study?
A stream is a series of area-specific courses that you take as part of your degree. It allows you to specialize in a particular field of study.
What is a water stream?
A stream is a body of water that flows on Earth's surface. The word stream is often used interchangeably with river, though rivers usually describe larger streams. Streams provide many benefits to humans.
What grain size can streams transport?
In a stream, the most easily eroded particles are small sand grains between 0.2 mm and 0.5 mm. Anything smaller or larger requires a higher water velocity to be eroded and entrained in the flow.
