Deposition is the laying down of some of the load carried by the river when energy decreases. The factors Influencing Deposition of materials includes;

1. Gradient; When gradient reduces the river’s speed decreases and hence its energy is reduced causing it to drop some of the heavy load.

2. Rivers Volume; When rivers volume decreases its energy also decreases causing it to deposit heaviest load then lighter ones.

3. Obstacles; Obstacles such as swamp vegetation and rock outcrop reduce the river’s speed and also trap some of the load thereby facilitating deposition.

4. River Bed Width and Depth; Where a rivers channel becomes wide and shallow there is less water per unit area and hence the river has lower capacity to transport so deposition of excess load begins.
