Hydrologists redefine aridity index to include river and groundwater flow—providing more accurate estimates
The aridity index is an invaluable tool used for estimating how dry (or how humid) a location is based on the precipitation and evapotranspiration occurring in the area. It is useful for predicting ...
Even though groundwater only makes up an estimated 0.61% of the water on Earth, it accounts for 98% of the available freshwater (Fetter, 1999). In many parts of the world (including southwestern North ...
Groundwater and surface water often are one closely interrelated system. Groundwater feeds springs and streams. Surface water recharges aquifers. The interaction of groundwater and surface water ...
