  1. divide
  2. watershed
  3. braided streams
  4. gradient
  5. discharge
  1. a total area that drains into a particular stream
  2. b slope over which the stream flows (i.e. if the headwaters are at 1000 meters and the stream flows 500 km to the sea, the gradient is 1000m/500km= 2m/km)
  3. c result when stream is fully loaded with sediment
  4. d total volume of water moving past a particular point over a given period of time (to calculate, need the channel dimensions to calculate area and the stream velocity: Q (discharge)= V* A
  5. e topographic feature separating water sheds

5 Multiple choice questions

  1. larger material that moves along the bottom of the stream
  2. ...
  3. point bars, oxbow lakes
  4. previously established meanders in area that is being uplifted-
    form from deep downcutting of meandering stream through hard bedrock. Shape of meanders is
    preserved in river canyon shape
  5. stream will cut channel down to base level (ultimate base level is sea level); local base level could be larger than stream or lake
