Increasing water use [] for an overview of HK water

** Water Quality in Hong Kong :**

Go to [] and study the report on river water quality in HK for 2007. Read through pages 6-11 and do the following: 1. In what ways are the rivers of HK a resource? 2. Describe the pattern of water quality shown on the map on p7. 3. What sort of things are actually tested to measure the Water Quality Index (see p7 and 29)? 4. What has happened to the overall quality of water in HK’s rivers since 1986 (p8)? 5. What reasons are given for the improvement? 6. Compare the water quality reports for the Eastern New Territories and NW New Territories (p9-11). Make notes on the similarities and differences and reasons for them.


 * Flooding: causes and control: **

Go to http://www.as.uky.edu/sites/default/files/elearning/module12swf.swf

**Causes of flooding:** As you go through the ‘Overview’, read the text and follow the instructions on the diagrams. List and explain each cause of flooding that you come to in slides 1-6. **Flood control:** Study the 5 common flood control methods in slide 7. List each one and say how it works. Then rank them according to their effectiveness. Explain your order and say what other factors may also be important and why.

**The 3 Gorges Project:**

Use the text books, Geography Review May 2007and research to produce a presentation on the TGP. Use headings such as The Purpose of the TGP, Impact of the TGP on the river regime, The TGP and flood control, The Impacts of the TGP and so on. Graphs of power output and river flow
