Landforms caused by rivers

• Meanders
• Oxbow lakes
• Deltas
• Valleys
• Flood plains

Meanders

• A meander is a loop-like bend in the course of a
  river.

4

• The water deposits sediment on the inside of the
  banks and carves away at the outside of the bank
  creating the meander.

5
Oxbow Lakes

• An oxbow lake is a meander that has been cut off
  from the rest of the river.

Deltas

• A delta is a landform built up of sediment
  deposited by a river into an ocean or lake.

8
The river is traveling quickly and can carry a
load of sediment. The ocean is not traveling as
quickly and cannot carry the same load, so the
load is dropped at the mouth of the river and
results in a delta.
