Alluvial Fan
Depends on the environment and mode of deposition. I think that you're thinking of an alluvial fan.
Alluvial fan- A fan shaped alluvial deposit formed by a streau where it's velocity is decreased.
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.

alluvial fan?
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.

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.
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).
An alluvial fan is a depositional feature which is formed when fast moving water comes out of a canyon, slows, and deposits the sediment it is carrying on a flat plain into a fan shaped structure.

Alluvial FansWhere a stream flows out of a steep, narrow mountain valley, the stream suddenly becomes wider and shallower. The water slows down, Here sediments are deposited in an alluvial fan. An alluvial fan is a wide, sloping deposit of sediment formed where a stream leaves a mountain range. As its name suggests, this deposit is shaped like a fan.
