Describe a feature of a lower stage of a river valley.

One feature of a lower stage of a river valley is the presence of floodplains. Floodplains are flat, low-lying areas adjacent to the river that are periodically inundated by floodwaters. These areas are typically covered with fertile soil deposited by the river during floods, making them ideal for agriculture. Floodplains also provide important habitat for a variety of plant and animal species. However, they are also prone to flooding, which can cause damage to crops, infrastructure, and homes located in these areas.

Braided Channel:

In the lower stage of a river valley, where the gradient is gentler and the river has a greater volume of water, it often forms a braided channel. This feature is characterized by:

- Multiple, interconnected channels that divide the river into a network of smaller streams
- Channels that shift and evolve over time due to the deposition and erosion of sediment
- Shallow water depths and high sediment load
- A wide, flat valley floor with a gentle gradient
- Numerous sandbars and islands formed from sediment deposition
