A good example would be the ones in Death Valley, California. An alluvial fan is basically a fan-like structure formed from the mouth of a flattened and spread out stream (it looks like a fan).
This is known as an Alluvial Fan. Please see related links.
The river spreads and becomes shallower and the flow velocity decreases meaning that it has less energy and so is unable to transport the larger clasts (pieces of rock) and so these settle out of the fluid to form an alluvial fan.

an alluvial fan
Alluvial fans usually created as flowing water interact with mountains. It is a triangle-shaped deposit of sand, gravel and smaller pieces of sediment. There is also a type of alluvial fan that can be found underwater which is the subaqueous fan.
The River Severn does not have an alluvial fan. Rivers that empty into estuaries do not have alluvial fans.
The alluvial fan deposited the river's sediment into the sea, creating a delta. As the glacier melted, an alluvial fan formed at the base of the mountain.

a fan-shaped accumulation of alluvial.
The mineral deposition in this alluvial fan is very unusual for this part of the continent.
The bold parts are the differences:An alluvial fan is fan-shaped alluvial deposits created when fast flowing rivers slow down. A delta is a triangular area of alluvial deposits where a river divides before entering a large body of water.If you dont understand:An alluvial fan is just alluvial deposits in a fan shape. A delta is alluvian deposits in a triangular shape. Where and how they are created are totally different.Hope this helped (;

An alluvial fan is a fan-shaped deposit that is created when a fast flowing river slows down. Alluvial fans develop where streams issue from canyons onto adjacent valley floors and deposit sediments derived through the erosion of rocks upstream.
They both are fan shaped
