A bird's foot delta forms at a river where waves, tides and currents are very weak.Deposition of large amounts of fine sediments occurs at the river mouth. The deposits block the channel of the river, which then divides into few distributaries.Each distributary continues to deposit its load maintaining levees as it extends into the sea. Some distributaries extended further than others creating the shape of a bird's foot.
