CH 14: WATER RESOURCES
1. Briefly describe Earth's water supply. Compare amounts of salt water and fresh water. Compare amounts of frozen fresh water and water available for human use. Define watershed and groundwater.
2. Summarize water use in the United States and the world.
3. List four causes of water scarcity. Describe the factors which play into a positive feedback loop creating water stress. Assess the significance of water resources for international relations.
4. List five ways to increase the water supply. List advantages and disadvantages of each strategy. Summarize a key lesson learned from the following case studies: the Colorado River; Egypt's Aswan High Dam; the California Water Project; the James Bay project; the Aral Sea disaster.
5. Describe the role of groundwater in supplying fresh water. Assess our current use of groundwater: is it sustainable use? Determine which principles are best illustrated by the Ogallala Aquifer experience. Distinguish between riparian rights and prior appropriation as to regulate water use.
6. State the percentage of water wasted throughout the world. Briefly describe measures which can be taken to reduce water losses through irrigation, industry, and home use.
7. Describe the history of the development of the Columbia River Basin. Summarize the lessons learned from the problems that were generated and the plans to address those problems.
8. List three ways that humans contribute to flooding. List four strategies humans employ to minimize the risks of flooding. Analyze the water problems of Bangladesh. What key principles are illustrated by this case study?
9. List and describe four ways humans use to control flooding. Evaluate which of these strategies is likely to have the best long-term results.
10. Describe the pieces that contribute to a picture of sustainable water use.
