varied features are seen in the river course at every stage. observe the diagram ( figure ) and answer the following questions by analyzing the features of these three courses
1) In which stage is the intensity of erosion more ?
2) which process result the land forms developed in the lower course ?
3) in which state the amount of sediments is high
please answer me
don't post irrelevant answer

Answer:
The volume of water in a river is at its greatest in the lower course. This is due to the contribution of water from tributaries. The river channel is deep and wide and the land around the river is flat. Energy in the river is at its lowest and deposition occurs.
FLOODPLAIN
Rivers flood on a regular basis. The area over which they flood is known as the floodplain, and this often coincides with regions where meanders form. Meanders support the formation of floodplains through lateral (sideways) erosion.
When rivers flood the velocity of water slows. As a result of this, the river’s capacity to transport material is reduced and deposition occurs. This deposition leaves a layer of sediment across the whole floodplain. After a series of floods layers of sediment form along the flood plain.
