What determines the speed of a stream?
The velocity of a river is determined by many factors, including the shape of its channel, the gradient of the slope that the river moves along, the volume of water that the river carries and the amount of friction caused by rough edges within the riverbed.
What affects stream discharge?
The velocity of the water affects it; faster water means more passes per second so more discharge. The width and depth of the river also affects it; a larger river at the same speed will have higher discharge.
What conditions would cause a stream’s velocity to increase?
Flood Erosion and Deposition: As flood waters rise, the slope of the stream as it flows to its base level (e.g., the ocean or a lake) increases. Also, as stream depth increases, the hydraulic radius increases thereby making the stream more free flowing. Both of these factors lead to an increase in stream velocity.
What are the factors that increase downstream in a graded stream?
Distance downstream: velocity increases the further downstream you go because of gravity, less frictional resistance than upstream, and tributaries.
Which of the following is not a factor that influences flow velocity?
Answer and Explanation: The factor that does not influence stream velocity is b. stream elevation.
What determines the speed of a river?
The speed of a river varies from close to 0 m/s to 3.1 m/s (7 mph). Factors that affect the speed of a river include the slope gradient, the roughness of the channel, and tides. Rivers tend to flow from a higher elevation to a lower elevation. The gradient is the drop of the elevation of a river.
Which of the following does not influence a river’s velocity?
Answer and Explanation: The factor that does not influence stream velocity is b. stream elevation.
How does channel shape affect stream velocity?
Channel shape and roughness affect a river's velocity. 1. Generally a narrower, more circular river channel allows faster flow of water. Broader flat channels tend to slow a river down.
Which of the following is not a factor influencing a streams flow velocity?
The factor that does not influence stream velocity is b. stream elevation. While gravity is what causes water to flow through the stream the actual elevation of the stream itself has no effect though factors like channel size and shape water volume and the gradient of the land itself do.
Which of the following factors influence a stream’s flow velocity select all that apply?
Gradient, cross-sectional shape, channel size and roughness, and discharge all affect a stream's flow velocity.
Which of the following is not a factor that controls stream behavior?
Where is the water table in a swamp? Which of the following is not a factor that controls stream behavior? The sediment load.
What factors affect flow rate?
Flow patterns in a fluid (gas or liquid) depend on three factors: the characteristics of the fluid, the speed of flow, and the shape of the solid surface. Three characteristics of the fluid are of special importance: viscosity, density, and compressibility.
Which factors influence the size and shape of a stream’s channel?
Stream channels are scaled to the amount of water and sediment they convey. The amount and size of bed sediment, composition of bank material, type of channel vegetation (both riparian and in-stream), and valley morphology (slope and width) influence channel size and shape.
What are the factors that affect the river?
The factors determining the flow of a river are 1.Volume of water 2.Rock structure 3.Slope of the terrain 4. Amount of sediments.
- Volume of water.
- Rock structure.
- Slope of the terrain.
- Amount of sediments.
What are three factors that affect water movement?
Explanation. The three factors that describe the movement of surface water in streams and rivers include gradient, river flow and stream load.
What factors affect stream speed quizlet?
What three variables influence the speed of stream flow? Stream gradient, stream discharge, and channel growth.
What factors affect stream quality?
the geology of a stream – what the bottom or substrate of the stream is formed from. the surrounding land cover, soil types and activities carried out on the land. topography – the steepness of surrounding land. the source – how much it is fed by overland flow or by water from springs and wetlands.
Which factors influence the size and shape of a stream’s channel quizlet?
The size of a stream channel is determined by the amount of water supplied from the drainage basin….
- sediment production.
- sediment transport.
- sediment deposition. Concept 13.2.
- Four drainage patterns and why.
Is flow rate affected by pressure?
Flow rate is the effect. Higher pressure causes increased flow rate. If the flow rate increases, it is caused by increased pressure.
How does pipe size affect flow rate?
In a fluid passing through a pipe, a reduction in the diameter of the pipe can compress the flowing fluid. It flows faster, which increases the flow rate. And if the diameter increases, then the flow rate reduces.
What factor determines the size of a river?
The headwater and embouchure are used to determine the length of a river. Unlike embouchure, which is easy to locate in the data, the headwaters of large rivers are difficult to find.
Which of the following factor does not affect the movement of ocean water?
The correct answer is Coriolis Force.
Which of the following factors does not affect the distribution of groundwater?
The correct answer is Distance from the sea.
What does not affect a stream’s velocity?
The factor that does not influence stream velocity is b. stream elevation. While gravity is what causes water to flow through the stream, the actual…
What are three factors that affect the rate of stream erosion quizlet?
So what determines how much material a stream can erode? A stream's gradient, discharge, and load are three main factors that control what sediment a stream can carry.
What are the three factors that affect water quality?
Water quality is defined in terms of the chemical, physical, and biological content of water. The water quality of rivers and lakes changes with the seasons and geographic areas, even when there is no pollution present.
What affects water quality and stream flows?
The volume of stream flow is determined by many factors. Precipitation is of course the primary factor- the more rain or snowmelt, the higher the flow. However, there is usually a lag period between the time a storm reaches it highest intensity and the time the stream reaches it peak flow.
How does density affect flow rate?
Flow Rate of a process line is the rate at which a fluid is passing through it. )is the mass per unit volume of a material. Fluid with high density means more number of molecules per unit volume that means more viscous or heavier and more energy is required to move the fluid resulting low velocity.
Does length affect flow rate?
Flow rate varies inversely to length, so if you double the length of the pipe while keeping the diameter constant, you'll get roughly half as much water through it per unit of time at constant pressure and temperature.
What are the factors affecting the river?
Factors affecting river regimes: precipitation including storm hydrographs, temperature, vegetation, land-use, water abstraction, dams.
