River deltas form when a river transporting sediment reaches a body of water, such as an ocean, sea, or lake, where the velocity of the river slows down. As the water slows, sediment carried by the river settles and accumulates at the river's mouth, creating a landform shaped by the interplay of deposition, erosion, and the influence of tides and waves. Over time, this accumulation can build new land, creating a delta characterized by various channels, wetlands, and ecosystems.
