Understanding the interaction between water supply and ecosystem demand
informs both the extent of moisture stress and the amount of water available
for storage.

The quantity element is described by five metrics: actual evapotranspiration
to precipitation fraction during drought, precipitation minus actual
evapotranspiration during normal conditions, drought sensitivity, change in
average climatic water deficit, and groundwater basin boundaries. Two metrics
are used to represent the element: actual evapotranspiration to precipitation
fraction during drought and precipitation minus actual evapotranspiration
during normal conditions (indicated by asterisks). The condition of water
quantity element is represented by the average of the condition scores for the
two metrics.

* Metric Name: Element Representation: Water Quantity   

* Translation: Where is water quantity greater?  

* Translation method and outcome: Condition scores range from +1 to -1 representing more favorable to less favorable conditions, respectively. **** The proposition of more favorable is based on the objective of greater water quantity.
