  1. Meandering Rivers

  2. Meandering Rivers • Constantly erode material - Cut bank • Constantly deposit material - Point bar • Change their channel course gradually • Create floodplains wider than the channel • Very Fertile soil • Subjected to seasonal flooding

  3. Formation of Meanders

  4. Point bar deposits

  5. Point Bar Deposits Point bar deposits grows laterally through time

  6. Cut bank erosion Point bar deposits } Meander loop

  7. Formation of an Oxbow

  8. Meandering stream flowing from top of screen to bottom

  9. Maximum deposition Maximum erosion

  10. Meander scars Oxbow Lake Oxbow cuttoff

  11. Things to Remember • Rivers are part of a larger hydrologic system • The have three main components: • Drainage (Tributary) systems - collect water • Transport Systems - move water along • Alluvial fans, braided streams, meandering streams
