This loss of velocity means the water can no longer carry the full load of sediment—sand, silt, clay, and gravel—that it picked up while flowing over land. Bird’s Foot Deltas Bird’s foot deltas occur when a river carries a very heavy sediment load and deposits it rapidly into a standing body of water with minimal wave or tidal action.

How Deltas Are Formed: The Science of Deposition The formation of a delta is a direct result of the river losing energy. They provide critical nursery habitats for fish, shellfish, and countless bird species.
The balance between the river’s sediment supply and the energy of the receiving water body dictates the final shape and structure of the delta. This continuous process of erosion upstream and deposition downstream is what builds and sustains these fertile landscapes.

They often contain rich reserves of oil and natural gas, making them vital energy zones. The river splits into several distributaries that deposit sediment in a curve, creating a pronounced, rounded edge.
