erosion and deposition
100
This another name for the final stage of a river.
lower course of the river
100
The action of deposition comes when the river speed is slow that cuts off the neck of the meander and results in this landform.

traction
200
Sections of the river where the water flows quickly and turbulently over a shallow region of the river, leaving rocks as steep outcrops in the upper stage of the river.
