Flooding impacts and solutions

I can explain the short and long term impacts of flooding and describe ways that flooding can be reduced.

Lesson details

Key learning points

  1. River flooding can cause short-term and long-term problems.
  2. Digital maps can be used to show areas at risk from flooding.
  3. The impacts of flooding can be reduced by warning people in advance.
  4. The risks of river flooding can be reduced by building embankments and planting trees.

Common misconception

Flooding only causes bad impacts.

In some parts of the world flooding can bring sediment to the soil which helps crops grow.

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.

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.
