Study Notes

Groundwater: water that infiltrates the ground surface and exists below it in a porous structure, consisting of water and air that fills pores underground.
Watershed: a division of drainage that feeds into a specific point, often in mountainous areas.
Aquifer: the underground soil or rock through which groundwater travels, separated from atmospheric pressure by an impermeable material.
Groundwater estimation: peak runoff flow rate (Q) can be estimated as a function of precipitation intensity, land use, and watershed area using the Rational Method.
Watershed pollution: major pollution sources come from within the watershed, with exceptions being pollutants from coal combustion.
Water scarcity: up to 60% of the human body is made up of water, and water is needed for energy production through the Energy Water Nexus.
Water scarcity challenges: 3,800 km3 of water is withdrawn every year, while 2,100 km3 is consumed, and demand for water has grown faster than population.
