Water Resources: Groundwater Flashcards
Water is considered to exist in a ____ system
closed
Evaporation
Net movement of free water molecules away from a west surface into air that is less than saturated.
Transpiration
Water moves into the atmosphere from land environments, including from the soil into plant roots and passing through their leaves to the air in a process called transpiration
Evapotranspiration
Evaporation and transpiration from Earth’s land surfaces together
Interception
when precipitation strikes plants or ground cover rather than the ground.
Two basic pathways for precipitation reaching Earth’s surface
Flows Overland
Soaks into soil
Principal pathways for precipitation
Flows Overland
Soaks into soil

Transpiration + Evaporation
Principal pathways for precipitation
Flows Overland
Soaks into soil (infiltration and Percolation)
Interception
Through-fall
Collection
Stemflow
Transpiration + Evaporation
Infiltration
the movement of water from the ground surface into a soil or into a porous rock or sediment
Percolation
The downward movement ???
Infiltration capacity determines…
the amount of water that can flow downward below Earth’s surface
Infiltration capacity criteriobn
Intensity and duration of rainfall??
Water Budget
derived from measuring the input of precipitation and its distribution and the outputs of evapotranspiration and surface runoff.
also includes stored moisture.
Water Demand
Potential evapotranspiration (PE).
The amount of water that would evapotranspire under optimum moisture conditions …????????
Evapotranspiration
an actual expenditure of water to the atmosphere
