All you need to know about Deposition in Rivers!
Deposition is the process by which a river drops the majority of the material it is transporting, including things like mud, sand, silt and rocks/pebbles, onto an area of land. These areas can include river banks, the river bed, or the river mouth. Deposition occurs when the river's speed slows down dramatically.
Deposition can take place due to a number of reasons:
At the mouth of a river is one of the most common places that deposition will occur over its entire course. This is becuase at a river mouth, the river is at its slowest pace due to its wide width and its connection into the sea. This process can form deltas, which are a result of the river depositing material at a quicker rate than the sea can remove it.
There are three types of deltas:
The Mississippi Delta is a great case study to use to illustrate the way deposition works, as well as the landforms it can create.
