Unit: Hydrology & River Processes |
Aim: Able to describe and explain how water makes its way back to the oceans/seas. Should be able to discuss the processes of erosion, transportation and deposition that occur & the landforms that these create. |
| Revision Resource: www.i-study.co.uk/Rivers.html |
| Lesson 1 |
Watercycle
Tasks
1) Build up watercycle on the board - key words.
2) Write definitions for the key words:
- evaporation
- transpiration
- evapotranspiration
- condensation
- precipitation
- infiltration
- surface run-off
- groundwater
- groundwater flow
3) Permeable & impermeable surfaces |
| |
Homework: Revise watercycle & learn the key words |
| Lesson 2 |
River Features
Tasks
1) Labelled diagram of a river basin. Each of the labels defined:
- source
- tributary
- confluence
- mouth
- drainage basin
- watershed
2) Characteristics of river near source compared to mouth (water volume, speed, river bed material). |
| Lesson 3 |
Erosion, Transportation & Depositon
Tasks
1) Erosion: what it is & types (hyraulic action, abrasion, atrition, corrosion), labelled diagrams.
2) Transportation: types (traction, saltation, suspension, solution), & link to rivers energy. |
| |
Homework: World rivers w/s |
| Lesson 4 |
Waterfalls & Meanders
Tasks
1) Erosive processes creating waterfalls - labelled diagram.
2) What are meanders & why do they change (innner & outer banks of bends).
3) Oxbow lakes. |
| |
Homework: Meanders w/s |
| Lesson 5 |
Deposition & deltas
Tasks
1) Why does deposition happen & in which sections of rivers
2) What are deltas, why do they form, distributaries.
3) Importance of some deltas (Nile) for agriculture & dangers facing them (Aswan High Dam). |
Aim: able to explain the causes of flooding, describe & explain the effects, and offer suggestions as to how flooding can be prevented or managed. Case Study: Bangladesh |
| Lesson 6 |
Flooding Video
Natures Fury: Floods. Take notes on causes, effects & solutions to floods. |
| Lesson 7 |
Causes of flooding
Tasks
1) Next 3 lessons will build up an A3 poster.
2) Causes: deforestation in Himalayas (reasons), silting, flat land, monsoon (what).
3) Pictures displaying each of the causes in 3rd of the page. |
| |
Homework: Research effects of flooding in Bangladesh |
| Lesson 8 |
Effects of flooding
Tasks
1) Effects: damage to buildings, infra-structure, loss of crops, water contamination, disease, death/injury.
2) Discussion about each effect & its impacts & long or short term. |
| Lesson 9 |
Solutions/ suggestions
Tasks
1) Different ways in which rivers can be managed (hard & soft engineering).
2) Ways in which people can prepare for floods to limit the impact that they have. |
