Highly fertile silt. The structure of the soil particles is like sand.
It is called a delta
clay
A river delta is formed from the deposition of sediments carried by a river as the river enters an ocean, sea, lake, or another river. This is because the flow velocity decreases significantly and the fluid loses the ability to transport sediment.
The two kind of land forms created by deposit of sediment are: alluvial fan and delta.
dark, rich and soft
sedimentary rocks
A Delta about 160 kms wide including about 500 channels.
bed load, a large load
A wave-dominated delta.
The differ based on the kind of sediment that they are composed of, the color of their sediment, and the size of their sediment.
They are both fertile, almost oasis like places. the Nile River Delta is a fertile and luscious place. The Nile River Valley is about the same, except a delta isn't the same thing as a valley.
