A River System

  • It is a natural stream of water formed from runoff that flows in a channel. Confluence tributaries distributaries River source Delta^ River mouth Meanders deposited sediments
  • Refers to the area drained by surface runoff into a particular set of channels
  • Shape and size is determined by the shape of the land
  • The amount of water flowing into the river is linked to the size of the drainage basin
  • Size of a river influences its ability to erode the land and carry away materials mouth watershed river source tributaries drainage basin Drainage Basin
  • Watershed or water divide at the tops of a chain of mountains and hills divides drainage basins from one another The Drainage Basin
  • Watershed is identified on the map by the highest value of contour lines and from particular heights given for the peaks on the highland mouth watershed river source tributaries drainage basin Drainage Basin
