Formation of Flood Plains

Eroisional Flood Plain is made when a stream cuts into a deep channel and into is banks.

Aggradational Flood Plain is created when streams lay down thick layers of sediment. The stream's sediment becomes small and its speed decreases, and sediment is dropped from higher regions near the source.


Features that are included in Flood Plains

The Ganges Delta and the Laramie River are included in examples of the flood plains. This feature provides the richness of the allubial soil. This could be set off by cyclones and monsoon rains. These weather forms can cause loss of human life in major populated regions.
