Riverbottoms
Riverbottoms, also known as floodplains or alluvial plains, are flat areas of land adjacent to a river. They are formed by the deposition of sediment carried by the river over long periods of time. When a river overflows its banks, it deposits sediment onto the surrounding land, gradually building up the riverbottom. This process creates fertile soil, making riverbottoms ideal for agriculture.
The composition of riverbottom soil varies depending on the type of sediment deposited. It can range from
However, riverbottoms are also prone to flooding, which can pose risks to human settlements and infrastructure.
