Extending water resources

Free Course Free Course

Water is arguably the most important physical resource as it is the one that is essential to human survival. Understanding the global water cycle and how we use water is essential to planning a sustainable source of water for the future. In the UK there are areas where water supplies are limited, shown by recent droughts. Globally, there are many areas that do not have enough water to support the current population adequately. Decisions will have to be made on the best way to use water in a world where there is climate change. This course, Extending water resources, examines the options.

After studying this course, you should be able to:

  • discuss ways of extending sources of fresh water involving both the unused parts of the hydrological cycle, and new ways of using existing water sources.

Existing supplies of water will have to be used in different ways, or new sources will have to be found, to satisfy a greater demand for water in the future. This course looks at alternative methods of exploiting water resources by water transfer, estuary storage, and conjunctive use, and also at methods for creating new supplies of fresh water by desalination and rain-making.
