Clues

  • Amount of sediment removed by overland flow from a unit area of ground over a unit time. (4, 2, 8, 5)
  • As rivers lose momentum, they deposit material. (3, 2, 4, 7)
  • Erosion by laminar flow (4, 2, 5, 7)
  • Flat valley floors that may periodically flood. Terraces may form as rivers erode the valley. (8, 11)
  • The 3D catchment zone area for a river. (4, 2, 3, 9)
  • The stream's capacity for material. (4, 2, 3, 7, 4)
  • Where sediment comes to rest at the bottom of a slope before it reaches water. (4, 2, 9)
  • Where small particles are bounced along the riverbed. (4, 2, 9)
  • Where streams split around bars and become braided channels (6, 12)
  • Where turbulence in the flow produces small channels-these may eventually form tributaries. (6, 4, 7)
