Could you give an example of a delta?

The Mississippi River Delta is a region of coastal wetlands and marshlands at the mouth of the Mississippi River in the Gulf of Mexico. It is roughly triangular in shape with New Orleans located near the center of the base and Baton Rouge near the apex.

Formed by centuries of sediment deposition from the Mississippi River, the delta is one of the world's largest deltas and continues to grow at a rate of several square kilometers per year.

Today, the Mississippi River Delta faces significant environmental challenges as a result of rising sea levels, land subsidence, and the impacts of human activities such as navigation channels, levee construction, and oil and gas extraction. These challenges threaten the ecological integrity of the delta as well as the economic and cultural well-being of the communities that reside there.
