Research & Theory
River channels effectively flow in drainage basins, and your task is to investigate the EROSION and DEPOSITION processes and evidence for these within those river channels.  You could measure characteristics shown on the diagrams below. 

The Bradshaw model characteristics should be affected by erosion and deposition and erosion/deposition will be affected by some of those characteristics. 

Long and cross profiles will also indicate which erosion and deposition processes are opccurring along the River Breamish in Northumberland National Park

I have tried to collate all of the relevant theory pages here.

 You can investigate more on Drainage Basins, Long and cross profiles here.

For the erosion and deposition processes, you should explore the resources on this page.
