Stream Dynamics and Sediment Transport Quiz

What is the relationship between stream discharge and the size of particles it can carry?

• Higher discharge allows a stream to carry larger particles.

• Stream discharge has no effect on the size of particles it can carry.

• Lower discharge allows a stream to carry larger particles.

• Stream discharge only affects the speed of particles, not their size.

How does an increase in particle size affect stream erosion?

• It decreases erosion due to less water flow.

• It increases erosion by creating more friction.

• It has no effect on stream erosion.

• It decreases erosion by stabilizing the stream bed.

Which of the following is NOT a factor affecting stream discharge?

• Precipitation

• Temperature

• Vegetation type

• Color of the water

What role does sediment transport play in stream ecosystems?

• It primarily pollutes the water.

• It helps in the formation of new habitats.

• It has no significant role.

• It decreases biodiversity by covering the stream bed.

Which factor does NOT directly affect sediment transport in streams?

• Stream gradient

• Water pH

• Stream velocity

• Particle size

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.

How does vegetation along a stream bank affect its discharge?

• Increases discharge by adding water.

• Decreases discharge by absorbing water.

• Has no effect on discharge.

• Increases discharge by reducing evaporation.

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.

What effect does urbanization have on stream discharge?

• Increases discharge due to more impermeable surfaces.

• Decreases discharge due to higher water usage.

• Has no significant effect.

• Decreases discharge due to increased evaporation.

How does the shape of streambed particles affect sediment transport?

• Round particles are transported more easily than angular ones.

• Angular particles are transported more easily than round ones.

• Shape has no effect on transport.

• Only size, not shape, affects sediment transport.
