deltas and placer deposits
Besides deltas and placer deposits, stream deposits can also lead to the formation of alluvial fans and floodplains. Alluvial fans occur where a stream flows out of a narrow canyon into a wider area, depositing sediment in a fan-shaped pattern. Floodplains are flat areas adjacent to rivers that become covered with sediment during flood events, enriching the soil for agriculture. These features contribute to the shaping of landscapes and ecosystems.

Placer deposits.
A delta is a result of deposits that are carried by a river. This is usually formed at the mouth of the river.
many sand and gravel deposits
The origin of the rare earth deposits in the Northern Quebec is as a result of the volcanic activity within the area.
A structure built up by stream deposits at the foot of a mountain is called an alluvial fan. Alluvial fans form when rivers or streams carrying sediment from the mountains suddenly lose velocity and deposit the sediment in a fan-shaped pattern.

Outwash gravels are commonly periglacial materials deposited by the water phases associated with the glacier. From meltwater moved around by the stream flowing from a glacier, or by cutting through recent moraines. Glacial material is easily distinguished from alluvial stream material, by the high proportion of clays among the gravels. But you could speak of outwash from an ordinary stream cutting through an existing alluvium. In short, it is usually found downstream of larger gravel and sand deposits.
Point bars, cut banks, and levees are common types of deposits in a meandering stream. Point bars are formed on the inside of meander bends where slower flow allows sediment to settle, while cut banks are eroded on the outside of bends where the flow is faster. Levees are built up along the banks of the stream during flooding events.
