Strategies to increase water supply
Lesson details
Learning outcome
I can describe different strategies used to increase water supply and outline the advantages and disadvantages of California's water project.
Key learning points
- Different strategies can be used to increase water supply.
- Strategies to increase water supply include diverting supplies, increasing storage and desalination
- The California State water project is a large-scale water transfer scheme with advantages and disadvantages.
Keywords
Water transfer - the movement of water (through pipes or along rivers) from areas of water surplus to areas of water deficit
Desalination - the industrial conversion of saltwater into freshwater, commonly in arid or semi-arid areas
Common misconception
Dams and reservoirs guarantee a reliable water supply for many years into the future.
Although dams and reservoirs do provide a reliable and easily-controllable source of water, this supply is not guaranteed. Over time, sediment will build up and reduce the capacity of the reservoir. Also, reservoirs can dry up during droughts.
Teacher tip
ArcGIS Online provides a wide array of useful layers related to water supply, including for example location of desalination plants in Saudi Arabia.
