A river delta.
The triangular section of land formed at the mouth of a river is called a delta. Deltas are created as the river deposits sediment and soil brought downstream over time, resulting in a unique ecosystem with a diverse range of plant and animal life.

Delta is the name
Delta - a delta is a landform that forms at the mouth of a river, where sediment carried by the river is deposited and accumulates in a triangular or fan-shaped pattern. Deltas are typically rich in nutrients and support diverse ecosystems.
mouth
A delta is built up by sediment transported by a river and deposited at its mouth where the river meets a body of standing water, such as a lake or ocean. Over time, these deposits accumulate and form a triangular or fan-shaped landform.
Rivers create river deltas through deposition, which are triangular-shaped deposits of sediment at the river's mouth. They also form natural levees, which are raised areas of sediment along the river banks, built up from deposited materials during floods.

a delta
The triangular-shaped landforms caused by deposited sediment are called deltas. Deltas typically form at the mouth of rivers where the flowing water slows down and deposits sediment, creating a triangular shape as it spreads out into a larger body of water like a lake or ocean.
