river landforms-deposition

• what is a flood plain?

  the wide valley floor on either side of a river
• how are levees formed?

  -during a flood sediment spills over the banks and is transported by the water

  -as the water loses energy it deposits heavy material close to the river channel

  -over time it leads to a build up in the material forming raised areas of land called levees along the edges of river channels
• how do estuaries form?

  -the water is tidal so the rising tide pushes back against the flowing river water creating an estuary

  -as the rivers velocity reduces deposition occurs which causes sediment to build up
