Landforms in the middle and lower course

These can be natural or human

 To be able to explain how meanders, ox-bow lakes, floodplains and levees are formed

Watch the clip below on meanders and ox-bow lakes

Meander = a bend in a river

Oxbow lakes

 Read p in Understanding GCSE Geography and complete the following:  With the use of labelled diagrams, describe and explain the formation of a meander and oxbow lake, include the following terms – slip off slope, river cliff, erosion, deposition and meander scar.  Look at the worksheet with a diagrams 2a and b. Draw and annotate a cross section through the river between C and D and then between E and F.

Landforms are primarily caused by: processes of erosion processes of deposition a mixture of erosion and deposition deltasmeandersfloodplains waterfalls leveés oxbow lakes rapids v-shaped valleys interlocking spurs Which of the following landforms are the result of a mixture of erosion and deposition?

Floodplains

 Read p85 in Understanding GCSE Geography on Flood plains and levees.  Draw Figure 5 – The formation of a levee.  Describe and explain how a flood plain and levee are formed.

Name the river landform shown in this aerial photograph. What else can you identify? How can you tell that this is not the Upper Course of a river?

The River Conwy has deposited material in this section of its course. Suggest reasons why this has happened.
