The document discusses various river landforms found along different parts of a river's course. It defines key terms like load, sediment, river bed, and river bank. It also defines the four types of erosion and four types of sediment transport processes. The document describes how particle size, channel width, and depth change downstream. It then provides more details on specific landforms usually seen in the upper, middle, and lower course, such as V-shaped valleys, waterfalls, meanders, point bars, oxbow lakes, and deltas.

1. River landforms

2. Different landforms are found along the course of a river as the processes change along the long profile.

3. Define Load, sediment, river bed and river bank Define the four types of erosion Hydraulic action, abrasion, attrition, solution Define the four types of transport Traction, saltation, suspension, solution Describe how particle size, channel width and channel depth change down the course of a river.

4. You should be familiar with many of the names of fluvial landforms and have a basic understanding about how they are formed. But now you need to add more detail to you explanations Landforms usually found in the upper course of a river V Shaped Valley with interlocking spurs Waterfalls and gorges

5. V Shaped Valley with Interlocking Spurs Key words: Vertical erosion Mass movement Exogenetic sediment Turbulent flow

6. Waterfalls and Gorges Key words: Hard rock / soft rock Overhang and undercutting Plunge pool Retreat upstream

7. Landforms usually found in the middle and lower courses of a river. Meanders point bars and river cliffs Ox bow lakes Floodplains and terraces Braided channels Mudflats and deltas

8. Meanders Key words Sinuosity Helicoidal flow Thalweg Pools and riffles Cross section of a bend Point bar River cliff Lateral migration Downstrean migration

9. Ox-bow lakes Key Words Lateral and downstream migration High discharge Cut-off

10. Mudflats and Deltas Key Words Deposition
