Deposition
Geography: Cambridge International GCSE (2027 Exams), topic 1.7.3
Deposition
Deposition is when the sediment that a river is transporting is dropped. This happens in the middle and lower course of the river and in lower energy conditions. The reasons why rivers lose velocity and drop material are:
Reduced volume of water in the channel
Increased amount of sediment in the channel
Water becomes shallower
The river's mouth is reached
Test yourself on Deposition

Which of the following would cause a river to slow down and deposit sediment?
In which part of rivers does deposition NOT happen?
