What are the main features of delta?
Among the many factors that determine the characteristics of a delta are the volume of river flow, sediment load and type, coastal topography and subsidencerate, amount and character of wave and current activity, tidal range, storm frequency and magnitude, water depth, sea level rise or fall, and climate.
What is the difference between delta and mouth of a river?
The mouth of a river is where it meets an ocean, a lake or another river. If a river carries a great deal of silt, gravel, clay and sediment as it travels, and this settles out at its mouth, that area of land is called a delta.
