Lower River Course

The lower course of a river is where the land flattens, creating a wider, deeper channel. Erosion has broken down rocks into fine sediment, which the river carries towards its mouth. The gentler gradient means less energy for carrying sediment, resulting in a wider and deeper riverbed.

Wider Channel

The river's channel significantly widens in the lower course due to reduced erosion and deposition of finer sediments.

Deeper Channel

The increased time and reduced energy lead to a deeper riverbed compared to the upper and middle courses.

Fine Sediment

The sediment carried is much finer due to extensive erosion upstream, creating a smoother river flow.

Impact of Erosion and Deposition

Erosion plays a significant role in shaping the lower course's wide channel. Deposition of fine sediment contributes to the flatness of the riverbed.
