Where are delta rivers located at?

Delta rivers are located at the mouth of a river, where it meets the sea or ocean. They are formed when a river carries sediment and debris to the coast, which is then deposited and builds up over time. As the sediment builds up, it creates a delta, which is a low-lying area of land that is often triangular in shape. The river then splits into multiple channels as it flows through the delta, creating a series of smaller rivers that are known as distributaries. Delta rivers are found in many parts of the world, including the Nile River in Egypt, the Mississippi River in the United States, and the Ganges River in India.
