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.

Caves, rivers.
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.
