1. What is the meaning of a circulating
resource?
• What percentage of water is fresh?
• Where is most of our freshwater? Is it easily
accessible?
• What is fossil water?
• How does water circulate (use figure 1 to help
you describe the process)?
2. How Much RFWR is Available?
• How is RFWR calculated?
• What is green water? What is blue water?
• How are runoff and river discharge related to
the maximum RFWR?
• Can humans use all of the RFWR? Why or why
not?

4. How Will Water Use Change in the
Future?
• What accounts for the most water
consumption globally?
• How will recycling technology affect our
predictions of water supply and demand?
• What concerns do developing countries have
in the future?
5. What Effects Will Climate Change
Have on RFWR?
• How will sea level rise affect groundwater?
• How will will evapotranspiration,
precipitation, transpiration, and river
discharge likely be affected?
6. How Can Hydrological Science Help
Solve World Water Issues?
• What type of data is missing from global water
use?
• How does hydrology play a key role in policy?
