Rivers: What do you need to know?

Long and cross profiles, processes of erosion (hydraulic power, corrosion, corrasion, attrition), transport (traction, saltation, suspension, solution) and deposition.

The characteristics and formation of waterfalls, gorges, meanders, ox-bow lakes, levees, flood plains and deltas.

River basin management issues – the causes and effects of flooding in river basins in the context of both LEDCs and MEDCs. Mississippi and Bangladesh.

The short, medium and long term strategies used to attempt to manage the floods.

Contemporary issues concerning use of ‘hard’ v ‘soft’ strategies and attempts to
achieve sustainability.

The social, economic, environmental and political issues that have an impact upon
strategies and the values and attitudes of interested groups.

Look at Geography Room (A level blog) for notes/ powerpoints on the two river basin management case studies.

Population: What does the specification say?

Population:The balance between birth and death rate. Change due to migration.

Students should be able to recognise the global change in population over the past 2000 years and the contribution that birth and death rates make to this change and identify differences between the birth and death rates of MEDCs and LEDCs and the effect of migration.
