freshwater distribution, regional differences, economic factors
3 factors that influence water availability for humans
aquifers
small spaces found within permeable layers of rock and sediment where water is found
unconfined aquifer
an aquifer that is simply porous rock covered by soil
confined aquifer
an aquifer surrounded by a layer of impermeable rock or clay
water table
the uppermost level at which the water in an area fully saturates the rock or soil
recharge
the input process of water percolating into an aquifer
springs
water from an aquifer that naturally percolates up to the surface
cone of depression
an area where there is no longer any groundwater
saltwater intrusion
when the pumping of fresh water out of a well is faster than the recharge. Near coastal areas this can cause salt water to infiltrate the aquifer
Ogallala
largest aquifer in the United States
leaves
an enlarged bank built up on each side of the river
dikes
similar to a levee but built to prevent ocean waters from flooding adjacent land
dams
a barrier that runs across a river or stream to control the flow of water
reservoir
the area where water is stored behind the dam
fish ladders
a set of stairs with water flowing over them that have been added to some dams to help migrating fish such as salmon get upstream
aqueducts
canals or ditches used to carry water from one location to another
desalination
removing the salt from salt water to obtain fresh water
agriculture
the largest user of water around the world
furrow, flood, spray, drip, hydroponic
irrigation techniques
furrow irrigation
a trench that is flooded with water
flood irrigation
the entire field is flooded with water
spray irrigation
an apparatus that sprays water across a field
drip irrigation
using a slow dripping hose that is laid on or buried beneath the soil
hydroponic agriculture
crops grown in fertilized water and no soil
industry
the second largest user of water worldwide
households
the third largest user of water worldwide
