What feature is described as being similar to an alluvial fan?

An alluvial fan is a landform that typically forms at the base of a mountain or hill, where a stream or river spreads out as it exits a confined channel onto a wider area, depositing sediment in a fan-like shape. This occurs in areas of variable gradient, where the velocity of water decreases, allowing sediment to settle and accumulate.

The end of a drainage way acts as a point where water spreads out and loses its ability to carry sediment due to a reduction in slope. Like an alluvial fan, this area is characterized by the deposition of materials transported by water, creating a similar fan-shaped formation. The features are both shaped by the processes of erosion and sedimentation influenced by water flow dynamics.

In contrast, the summit area is the highest point on a slope, an upland toeslope is the lower part of a slope leading into a flatter area but does not specifically exhibit the fan-like deposition pattern, and an interfluve is the higher land between two river valleys which generally does not accumulate sediment in the same way as an alluvial fan.
