A-Level - Rivers: Lesson 1: Drainage Basins

This is a 2 hour ‘post-16’ lesson that investigates what drainage basins and open systems are for A-Level and IB Diploma students, it is not A-Level exam board specific though the geography is universal and can be easily tailored. The lesson is the first in a unit on freshwater and rivers.

**Key Aim: **

"To analyse the drainage basin as an open system with:

• Inputs: Precipitation of varying type and intensity
• Outputs: Evaporation and transpiration
• Flows: Infiltration, throughflow, overland flow and base flow
• Stores: Including vegetation, soil, aquifers and the cryosphere

Ease of use is the aim, the lesson includes a compact presentation with labeled, organised, handouts with printing instructions and is of course, proof read. If there are any issues with the files or if links are broken I’m happy to help.

These resources take me hours to pull together so please leave a review if they’ve helped you out in the classroom. :)

Happy teaching!
