1. River Land forms
Explain the stream channel processes (erosion, transport, deposition) and explain the resultant landforms found on floodplains.

2. Remember to try and identify which processes are related to the landforms

5. Land forms in the Upper course

6. The following landforms are erosional (Erosion is the main process occurring in the upper course. In particular, vertical erosion)

7. V shaped valleys and interlocking spurs
Both of these features tend to occur near the upper course of the river
Both vertical and lateral erosion will form wide V-shaped valleys

9. The river erodes downwards (vertical erosion) through processes such as abrasion and hydraulic action.

16. Potholes

18. Which erosional process is this?

20. Waterfalls

21. Why are waterfalls not often found in the lower course?
Because vertical erosion leads a river to it’s base level. In the lower course, the river is usually already closer to base level.

23. Landforms in the middle and lower course

24. The following landforms are depositional

26. Floodplains
A wide and low-lying plain found on both sides of a river covered with alluvium deposited by the river

28. Why do we say that a floodplain is depositional?

30. Levees

31. When the floods subside, alluvium is deposited on the floodplain
When the floods subside, alluvium is deposited on the floodplain. The larger materials, being heavier, are deposited at the river banks while the finer materials are carried and deposited further away from the river. The larger materials at the river banks build upinto embankment called levees.

35. Delta( found in lower course)
