Depends on your point of view. Alluvial fans are caused by rain washing earth and rock down the sides of mountains. Most typical view of this is in Death Valley, California.

What is formed by constructive erosion?
Constructive erosion forms features such as river valleys, alluvial fans, and deltas. It involves the deposition of sediment and soil to create new landforms and land surfaces.
What is a constructive landform?
A constructive landform is a geographical feature that is created by natural processes and adds material to the Earth's surface. Examples include sand dunes, alluvial fans, and deltas. These landforms are typically formed by the deposition of sediment, creating new land.
Where are alluvial fans located?
Alluvial fans are typically found at the base of steep mountain ranges or hills, where rivers or streams deposit sediment as they flow out and spread across a broader area. They are commonly seen in arid and semi-arid regions with high erosion rates. Examples of locations with prominent alluvial fans include Death Valley in California and the Himalayas in Asia.
Where do alluvial fans form?
Alluvial fans form at the base of steep mountain fronts, where fast-moving streams deposit sediment as they slow down and spread out onto flat plains or valleys. These fans typically develop in arid or semi-arid regions with sporadic heavy rainfall that triggers rapid erosion and sediment transport from mountainous areas.
How are alluvial fans deltas natural levees and moraines formed?
An alluvial is sediment deposited at the mouth of a stream. An alluvial fan is when that sediment creates an arching fan shape when it is deposited. The fan shape is created when the stream's slope is suddenly and abruptly reduced. For example, when a mountain stream, which flows at a sharp angle, suddenly emerge onto a flatter surface.
These form when weathered material is dropped offshore as sediment?

Why are alluvial fans called fans?

Does river severn have an alluvial fan?
The River Severn does not have an alluvial fan. Rivers that empty into estuaries do not have alluvial fans.
What is the origin and appearance of a bajada?

Where are alluvial fans?

What is a bajada in a desert?
A bajada is an alluvial plain formed at the base of a mountain by the coalescing of several alluvial fans.

What is formed by the intersection of several alluvial fans in one valley?
A bajada may be created. A bajada is a broad, gently sloping surface formed by the coalescing of alluvial fans.
