River Process

________________ is the laying down of sediment carried by wind, water, or ice.

• Sedimentation

• Deposition

• Weathering

• Erosion

It is the process of settling or being deposited as a sediment.

• Sedimentation

• Deposition

• Weathering

• Erosin

It refers to the force of air and water on the sides of rivers and in cracks.

• Abrasion

• Attrition

• Hydraulic action

• Solution

It is the wearing away of the bed and bank by the load carried by a river. Abrasion increases as velocity increases.

• Abrasion

• Attrition

• Hydraulic action

• Solution

______________ is the volume of water flowing through a river channel.

• Haydraulic radius

• River flow

• Velocity

• River discharge

_______________ refers to the speed of the river. Velocities increase in rivers that are deeper and when rivers are in flood.

• River flow

• River discharge

• Velocity

• Hydraulic radius

It is also referred to as horizontal turbulent flow.

• Laminar flow

• Turbulent flow

• Helical flow

• Pool

This occurs where there are higher velocities and an increase in bed roughness. Turbulence is associated with hydraulic action.

• Helical flow

• Turbulent flow

• Laminar flow

• Fast flow

Which of the following is transported through saltation?

• Clay

• Silt

• Pebbles

• Sand

The _______________ is a measure of a stream’s efficiency

• Hydraulic radius

• River discharge

• Wetted perimeter

• Cross-sectional area
