NYS ESRT Stream Velocity

What is the minimum water velocity necessary to maintain movement of 0.1-centimeter-diameter particles in a stream?

• 
  0.02 cm/s

• 
  5.0 cm/s

• 0.5 cm/s

• 20.0 cm/s

A stream’s velocity decreases from 100 cm/s to 5cm/s. Which size sediment particles will still be transported by the stream?

• pebbles, sand, silt, and clay

• sand, silt, and clay, only

• silt and clay, only

• clay, only

The largest sediment particles that can be transported by a stream traveling at a velocity of 250 centimeters per second are

• 
  boulders

• 
  sand

• 
  pebbles

• 
  cobbles

The largest particles that a stream deposits as it enters a pond are 8 centimeters in diameter. The minimum velocity of the stream is approximately

• 
  100 cm/sec

• 300 cm/sec

• 400 cm/sec

• 200 cm/sec

In terms of sediment transport, what is the significance of stream velocity?

• Higher velocities can transport larger particles.

• Stream velocity has no effect on sediment transport.

• Lower velocities can transport larger particles.

• Only affects the temperature of the stream, not sediment transport.

Which of the following conditions would most likely lead to increased deposition within a stream?

• An increase in the stream's slope or gradient

• A decrease in the stream's velocity

• An increase in the stream's velocity

• A decrease in the amount of vegetation along the stream banks

What happens to the carrying capacity of a stream as its discharge increases?

• It decreases.

• It increases.

• It remains the same.

• It first increases, then decreases.

What role does stream discharge play in the formation of deltas?

• High discharge is necessary for delta formation.

• Low discharge promotes delta formation.

• Discharge has no effect on delta formation.

• Only sediment type, not discharge, affects delta formation.
