What factors affect stream velocity?
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 are the 3 factors that affect the rate of stream erosion and velocity?
Our experiments will examine three variables that affect water flow in a stream and test for their effect on erosion: slope (gradient) of the streambed, total amount of water flowing in a streambed (discharge), and pulses (spikes) in water.
What two factors affect stream flow velocity or speed?
Water flow in a stream is primarily related to the stream's gradient, but it is also controlled by the geometry of the stream channel. As shown in Figure 13.14, water flow velocity is decreased by friction along the stream bed, so it is slowest at the bottom and edges and fastest near the surface and in the middle.
What affects the flow of a stream?
The flow of a stream is directly related to the amount of water moving off the watershed into the stream channel. It is affected by weather, increasing during rainstorms and decreasing during dry periods.
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.
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.
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 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 is a stream velocity?
Stream velocity is the speed of the water in the stream. Units are distance per time (e.g., meters per second or feet per second). Stream velocity is greatest in midstream near the surface and is slowest along the stream bed and banks due to friction.
Which of the following factors affect a stream’s flow velocity quizlet?
Gradient, cross-sectional shape, channel size and roughness, and discharge all affect a stream's flow velocity.
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 factors affect the streams flow velocity quizlet?
What Factors influence the stream's velocity? Factors that influence a stream's velocity include gradient, channel shape, and channel roughness.
What three factors describe the movement of water in streams and rivers?
The stream or river's gradient, flow, and stream load are three factors that describe the movement of surface water.
What factors affect stream speed quizlet?
What three variables influence the speed of stream flow? Stream gradient, stream discharge, and channel growth.
Which two factors will increase the rate of a stream’s flow?
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 five factors that determine the velocity of a stream quizlet?
Name and describe factors that control stream velocity.
- Gradient: slope of stream channel. -vertical drop per unit of horizontal flow.
- Channel Characteristics (size, shape, and roughness): -Friction slows down the water moving in a stream. …
- Discharge: the volume of water flowing past a point per second.
What three factors can influence the movement of surface water?
Explanation. The three factors that describe the movement of surface water in streams and rivers include gradient, river flow and stream load. Gradient refers to the change in elevation or the slope or steepness of the land.
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.
Which two factors will increase the rate of a stream flow?

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 factors influence flow?
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 of the following factor does not affect the movement of ocean water?
The correct answer is Coriolis Force.
What is stream velocity?
Stream velocity is the speed of the water in the stream. Units are distance per time (e.g., meters per second or feet per second). Stream velocity is greatest in midstream near the surface and is slowest along the stream bed and banks due to friction.
How does discharge affect the velocity of a stream?
As discharge increases, generally width, depth, and velocity of the stream also increase. A stream's velocity depends on position in the stream channel, irregularities in the stream channel caused by resistant rock, and stream gradient. Friction slows water along channel edges.
What are the four factors that affect flow rate?
Fluid flow in pipes is affected by many different factors:
- The viscosity, density, and velocity of the fluid.
- Changes in the fluid temperature will change the viscosity & density of the fluid.
- The length, inner diameter, and in the case of turbulent flow, the internal roughness of the pipe.
Which of the following factors influence the movement of ocean water?
Temperature, winds, gravitational pull of the sun, the earth and the moon, warm and cold currents are the factors that effects the movement of ocean water.
Which of the following factors influence ocean currents?
- The primary forces that influence the currents are: heating by solar energy; wind; gravity; Coriolis force.
- The secondary forces that influence the currents are: Temperature difference; Salinity difference.

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 3 factors that affect flow rate?
Fluid flow in pipes is affected by many different factors: The viscosity, density, and velocity of the fluid. Changes in the fluid temperature will change the viscosity & density of the fluid.
Which factors do not influence ocean currents?
3) Revolution of the earth does not cause ocean currents. Explanation: The movement of ocean water due to various factors like the rotation of the earth, gravity, the density of water, wind, and the sun is called ocean current. The winds cause ocean currents in the coastal regions on a localized scale.
