Session (1.1.4) River Processes

Partial Progress - Circles (browser only)

Objectives

By the end of this session, you should be able to:

understand the following processes that operate within a river:
- erosion: hydraulic action, abrasion, attrition, solution;
- transportation: traction, suspension, saltation, solution;
- deposition.

Engage

Watch the following videos introducing you to river processes:

WATCH – River erosion (Time for Geography)

WATCH – River transport (Time for Geography)

Learn

Read and make notes on pages 40 and 41 of your coursebook. Draw a cartoon or diagram to illustrate each of the erosion and transport processes. Labels are important in geography, so add them to help with the detail on your drawings.

Apply

Think back to the Bradshaw model in Session 1.1.2. Explain why particle size and bedload quantity change downstream. Complete tasks 2 and 3 on page 41 of your coursebook.

Apply

Read and make notes on pages 43 and 44 of your coursebook. This is bringing together what you have learnt so far in this topic. You will look at cross sections in more detail when you do map skills. Draw Fig 1.5 on page 43.

Extend

Read the information on the website to aid your understanding of these processes.

READ — River processes (Internet Geography)

Consolidate

Add the new key terms from this session to the glossary you started in session 1.1.1.
