Lesson details
Key learning points
- River flooding can cause short-term and long-term problems.
- Digital maps can be used to show areas at risk from flooding.
- The impacts of flooding can be reduced by warning people in advance.
- The risks of river flooding can be reduced by building embankments and planting trees.
Keywords
Digital map - Maps that can be viewed on a computer.
Embankment - Embankments are where the sides of the river are raised to stop water escaping.
Drainage basin - A drainage basin is the area drained by a river and its tributaries.
Evaporation - Evaporation is where liquid heats up and turns into a gas.
Common misconception
Flooding only causes bad impacts.
In some parts of the world flooding can bring sediment to the soil which helps crops grow.
For the final task pupils can make a model of a drainage basin which is likely to flood and one of a drainage basin which is not likely to flood.
