Labels to include: Groundwater storage Channel storage PrecipitationInfiltration CondensationPercolation Surface run offSoil moisture storage Channel flowThroughflow InterceptionGroundwater flow Surface storageEvaporation Interception storage Transpiration

5. Identify Locations where there is a wet climate and explain why Locations where there is a dry climate and explain why

6. 2.1 The Geography of Water Supply 2.1.1 Where does our supply come from? 1)Complete a cross section of California and add on key words as labels, Use page 54 parrot book. 2)Explain where California’s water supply comes from and what geographical factors control supply. 2.1.1 What Governs water supply? 1)Which factors govern water supply in different locations? uses

7. River systems transport this water, often at continental scale. Flows increase downstream as tributaries enter. Seasonal changes in temperature can create distinctive river regimes. The relationship between water inputs and outputs is water balance Geology Surface drainage occurs on rocks which are impermeable such as granite and clay. Permeable rocks like limestone, chalk and some sandstones store water, called aquifers. Climate Climatic zones are critical in determining water availability Equatorial / tropical areas have higher rainfall than temperate / arctic areas. High altitude areas have snowpack water reserves released in late spring. Monsoon areas have one main peak, equatorial areas two peaks. Some tropical areas experience recurring drought The geography of water supply and demand 97.2% Ocean & saltwater Physical influences on water supply and scarcity

8. 2.1.1 How much freshwater is there?

9. Page 36 handout 1.Calculate the % freshwater in the world, the % easily accessible and then the % in rivers. 2.What does this suggest about the amount of freshwater in the World? 3.Explain what finite means 4.Using p 60 Parrot explain what the World water gap means

10. 2.1 The Geography of Water Supply 2.1.1 Where does our supply come from? 1)Complete a cross section of California and add on key words as labels, Use page 54 parrot book. 2)Explain where California’s water supply comes from and what geographical factors control supply. 2.1.1 What Governs water supply? 1)Which factors govern water supply in different locations? 2)What is water used for? Use p36-8 handout to add further details, use a spider diagram. uses

11. 2.1.2 Water stress and scarcity 1.Using the atlas p74-77 suggest areas which might suffer water scarcity.

12. 2.1.2 Water stress and scarcity 1.Using the atlas p74-77 suggest areas which might suffer water scarcity. 2.Define water stress and water scarcity

14. 2.1.2 Water stress and scarcity 1.Define water stress and water scarcity 2.Using the atlas p74-77 suggest areas which might suffer water scarcity. 3.Explain which areas suffer Physical scarcity and suggest reasons why. (e.g. Rivers, geology, climate) 4.Explain which areas suffer Economic scarcity and suggest reasons why. 5.Make notes on the different sources of water p38-9 and the Case study – Beijing region scarcity – explain why this area is under water stress – handout p40. There is often a growing mismatch between water supply and demand, which can lead to water stress either locally, or across whole regions eg economic growth in the RICs such as China and India.

Make note son the three physical factors which link to water supply

17. 2.1.2/3 Human activity and water supply - California and the Colorado

18. P 55 What share of the Colorado lower basin goes to California? Why does it need so much water? Is it fair California gets this amount?

20. 2.1.2/3 Human activity and water supply - California and the Colorado River Using the textbook P52-9 Parrot and research produce a research paper on California’s water stress and management Write onto a word document and ensure you answer the following questions in your answer. Consider the use of diagrams and images if labelled. Be aware of plagiarism. Use a bibliography. The questions below will provide a structure. Save as California_Colorado_your name and provide a printed version due WED. Problems P52-3 and p55 1.What are the threats to Californian water supply? Make a table to show human and physical threats. 2.What additional problems are there for the Californian wetlands and waterways? Solutions P53 1.What are the solutions? Read p56/7 1.Note how agreements over the water of the Colorado have developed over the years. 2.What are the conflicts over this water? Do native American have rights also? Impact of human intervention p58/9 1.Make two spider diagrams explaining the impact of human activity on i) Sacramento River delta and ii) Salton Sea
