What causes a river to deposit sediment?

Answer 1

Most sediment washes or falls into a river as a result of mass movement and runoff. Other sediment erodes from the bottom or sides of the river. Wind can also drop sediment into the water. Hope I helped!

Answer 2

A bend in the river, or a river entering a large body of water, would cause a sufficient slowdown of the river such that sediment carried along in suspension will drop out of the rivers' main stream to the bed of the river, lake, or sea.

Answer 3

A river deposits sediment when it loses energy and its transporting capacity decreases. This can happen when the river slows down as it enters a larger body of water, like a lake or ocean, or when the volume of water decreases. Additionally, changes in the river's gradient, such as a decrease in slope, can also lead to sediment deposition.

Answer 4

Sudden/Increased water flow will cause the river sediment to become disturbed and then flow down stream.
