Key learning points
- There are many geographical enquiry questions that you can investigate along the course of a river.
- Data collection methods in a river landscape can examine flood management and a river's agreement to the Bradshaw model.
- Secondary data can provide contextual information about particular rivers and comparable data.
Common misconception
River processes are independent variables that shape river features.
Rivers are complex systems where processes and features both affect each other at different times. This means that students need to disengage with the idea that one variable is going to be independent of another as they present and analyse data.
Keywords
Channel morphology - the physical size and shape of a river channel, including the sediment (bedload) it carries
The bradshaw model - a theory about how river processes change from source to mouth
Flood management - strategies used to prevent a river over topping its banks following a period of intense rainfall
