The document provides information about the processes that shape rivers from their source to mouth, including erosion, transportation, and deposition of materials. Erosion can occur vertically downstream or laterally sideways as a river flows. Transportation involves four methods by which a river moves its load. Deposition happens when the river speed decreases causing it to drop larger materials first, such as when the gradient or velocity decreases or when it meets a lake.
