The formation of an alluvial fan can vary greatly depending on factors such as the volume of sediment, the slope of the terrain, and the rate of erosion. In general, it can take thousands to tens of thousands of years for an alluvial fan to fully form. The process involves the deposition of sediment carried by a river or stream as it loses energy and spreads out at the base of a mountain or hill. Over time, the sediment accumulates and creates the characteristic fan-shaped landform.
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.
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).

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.
Depends on the environment and mode of deposition. I think that you're thinking of an alluvial fan.

No
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 (;
No, Sediments deposited where a river flows into an ocean or lake builds up a land form called a delta. An alluvial fan is a wide, sloping deposit of sediment formed where a stream leaves a mountain range.
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.
