1. The hydrological cycle Saturated soil: Soil that can hold no more water. Unsaturated soil: Soil that still has space between its pores and can hold more water. Water table: The line between saturated and unsaturated soil. The water table can go up and down depending on the amount of rainfall and the amount of water being used. Condensation: When water vapour condenses and turns into water droplets i.e. clouds. Permeable: A surface that will allow water to pass through it. Non-permeable: A surface that will not allow water to pass through it. This means that water can not infiltrate. Porous: An object (or ground) that can hold water i.e. it has pores where water can be stored. Non-porous: An object (or ground) that can not hold water i.e. it does not have any pores

2. Human effects on the hydrological cycle? How can humans affect this cycle? Deforestation Urbanisation Reforestation and afforestation Irrigation Agriculture Industry Transport Dams

3. River flooding in an MEDC Case study: Boscastle – 2004 Task 1: Use google maps and the evidence on the following slide to determine the following: 1.Where is Bocastle? 2.The function of the village 3.The shape of the surrounding land 4.T shape of the river channel 5.The gradient of river 6.The height of banks 7.The proximity (closeness) of housing 8.Other human activity

5. Boscastle floods - 2004 Human and physical affects of the flooding Task 2: Using the resources provided or on this website: http://www.rgs.org/NR/rdonlyres/C45EDD5 F-95DE-4891-8ADC- 945393695F15/0/KS3_Flood_1Boscastlecas estudy.pdf http://www.rgs.org/NR/rdonlyres/C45EDD5 F-95DE-4891-8ADC- 945393695F15/0/KS3_Flood_1Boscastlecas estudy.pdf Design a table to show the HUMAN and physical causes of the flood Task 3: a) Find your own picture of Boscastle floods and annotate it to show how the environment and people could have been affected by the floods. b) Use the following video to explain how Boscastle was affected by the floods https://www.youtube.com/watch?v=F8Fy6d YRp5w Include: costs, short and long term effects!

6. Responses to Boscastle floods Task 4: Look at the recovery scheme above and the following resource http://blackpoolsixthasgeography.pbworks.com/w/page/22974794/Boscastle%20Case %20Study http://blackpoolsixthasgeography.pbworks.com/w/page/22974794/Boscastle%20Case %20Study For each of the responses explain how it would have helped handle to situation in Boscastle. More….. Do you think 4.5 million was a reasonable amount to spend on flood defences?
