River Processes

This term indicates the total length of the bed and the bank that is in contact with the river.

• wetted perimeter
• banks
• bed
• discharge

The volume of water passing a given point over a set of time.

• velocity
• speed
• volume
• discharge

How is discharge calculated?

• Multiplying the cross-sectional area of the river with the velocity of a river.
• Multiplying the average depth with the average width
• Multiplying the velocity with the wetted perimeter
• It is the same as the volume of a stream

True or False? Mountain streams on steep slopes have a low velocity because the water flows in a turbulent movement.

• True
• False

True or False? Deep narrow streams flow slower than shallow wide streams if all other factors are the same.

• True
• False

True or False? Rivers tend to flow slowest in their lower courses.

• True
• False

Where will the particle size in a stream be the smallest according to the Bradshaw model?

• Upper course
• Middle course
• Lower course

Where is the slope angle the steepest on a stream's longitudinal (long) profile

• upper course

• middle course

• main course

• lower course

Any form of water that falls to Earth’s surface from the clouds, including rain, snow, sleet, and hail

• desalination

• delta

• tributary

• precipitation

Change of state from a gas to a liquid

• evaporation

• condensation

• desalination
