Describe a feature of a lower stage river valley.

One feature of a lower stage river valley is the presence of wide floodplains. As the river flows downstream and loses elevation, it often meanders across the landscape, depositing sediment and creating flat, fertile areas known as floodplains. These floodplains are prone to flooding during periods of high water flow, but they also provide important habitat for a variety of plant and animal species. Additionally, the rich soil found in floodplains is ideal for agriculture, making these areas important for human settlement and food production.

Floodplain

The floodplain is a flat, low-lying area adjacent to a river channel. It is formed by the deposition of sediment during floods. In the lower stage of a river valley, the floodplain is typically wide and well-defined, with a gentle slope away from the river.

The floodplain serves as a natural buffer zone, absorbing floodwaters and reducing the risk of flooding downstream. It is also an important habitat for plants and animals, and it can be used for agriculture or recreation.
