Hydrological Process

It is the study of water as it moves on, and under and through the Earth’s surface.

• Evaporation

• Condensation

• Hydrology

• Water cycle

It refers to water loss from vegetation to the atmosphere

• Evaporation

• Transpiration

• Condensation

• Evapotranspiration

It refers to the water loss that would occur if there were an unlimited supply of water in the soil for use by the vegetation.

• Evapotranspiration

• Condensation

• Precipitation

• Potential Evapotranspiration

Which of the following is not a factor that affects evaporation?

• Vegetation cover

• Albedo

• Size of land

• Wind speed

It is the range of moisture content in which permanent wilting of plants occur.

• Wilting point

• PEVT

• Field capacity

• Infiltration capacity

It is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds

• Condensation

• Dew

• Precipitation

• Snow

Water that either falls through gaps in the vegetation or which drops from leaves, twigs or stems

• Interception loss

• Interflow

• Stemflow

• Throughfall

It is the process by which water soaks into, or is absorbed by, the soil

• Groundwater flow

• Field capacity

• Infiltration capacity

• Infiltration

Which of the following ground cover has the highest infiltration rate?

• Weeds and grain

• Old permanent pasture

• Bare soil

• Permanent pasture

It is water that flows over the land’s surface

• runoff

• soil moisture

• groundwater storage

• interception
