What factors influence 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 does stream velocity depend on?
Stream Velocity Depends on the Shape and Size of the Channel The stream is thus slowest at the bottom and edges and fastest near the surface and in the middle of the stream (where there is the least amount of friction).
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.
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 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.
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…
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 does not influence a river’s velocity?
Answer and Explanation: The factor that does not influence stream velocity is b. stream elevation.
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.
What factors control the Behaviour of a stream?
- 5 Basic factors control a stream's behavior:
- Width and depth of the channel.
- Channel gradient.
- Velocity of the water.
- The discharge- quantity of water passing a point on a stream bank during a given interval of time.
- Sediment load.
What factors affect stream speed quizlet?
What three variables influence the speed of stream flow? Stream gradient, stream discharge, and channel growth.
What three variables influence the speed of stream flow?
What three variables influence the speed of stream flow? Stream gradient, stream discharge, and channel growth.
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 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 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 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 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.
