A delta is formed.
The sediment itself is called silt, and it often is deposited at the mouth of rivers and forms a landform called a river delta.
Land formed from sediment build-up is called a delta. Deltas usually form at the mouth of rivers where sediment, such as sand and silt, is deposited as the water slows down and spreads out.
The greater the speed the less sediment deposited. A delta is where a river slows way down and sediment is deposited at the mouth of the river.
When sediment is deposited at a river's mouth, it forms a delta. Deltas are landforms created by the accumulation of sediment carried by the river and deposited as the river slows down upon reaching a body of water, such as an ocean or lake. Deltas are typically characterized by intricate networks of distributaries and are important areas for wildlife and habitat diversity.
The areas of sediment deposit where a river's mouth reaches flat land at the bottom of a mountain are known as alluvial fans. Alluvial fans are cone-shaped landforms that are created by the deposition of sediment carried by rivers as they flow from steep mountain terrain to flatter regions. The sediment is deposited at the base of the mountain due to a decrease in flow velocity as the river enters the flatter area.
A delta is a body of sediment deposited at the mouth of a river or stream where it enters an ocean or lake.
Rivers carry sediment, which when deposited at the beach, increases the land. Similarly, rivers can carry sediment away from a beach, also changing its shape. These two forces can work together to effectively move sediment from one area of the beach to another. Similarly, storms also move sediment.
Sediment plays a significant role in both river erosion and deposition. As rivers flow, they pick up sediment from the riverbed and banks, which can erode the landscape over time. This eroded sediment is then transported by the river and eventually deposited along its course or at its mouth, shaping the land through deposition processes such as delta formation.

Land formed at the mouth of a river by deposited silt is known as a delta. It typically forms when the river's velocity decreases as it meets the ocean, causing sediment carried by the river to be deposited, building up land over time.
Deltas are formed at the mouth of a river where it meets a body of water, typically the ocean, and consists of sediment deposited by the river. Floodplains are flat, low-lying areas adjacent to rivers that are prone to flooding and are formed by sediment deposited during floods. Deltas are specifically found at the river mouth, while floodplains extend along the sides of a river.
