  • Alluvial fans Water flowing from a higher level breaks down into foot slope plains of low gradient. Normally very coarse load is carried by streams in the upper reaches. It becomes too heavy to carry and is deposited in a low to high cone-shaped deposit called alluvial fan.
  • There is no stratification of river load as all the material (fine and coarse) is dumped together.
  • Streams make alluvial fans eventually shift course, forming many channels called distributaries.
  • Deltas They are like alluvial fans but are formed at different locations, i.e. near the sea.
