VI. Running Water (streams)

A. Basics
  1. stream - channelized flow of water
  2. energy
    1. gradient = vertical/horizontal
    2. channel shape
    3. channel roughness
    4. vegetation
B. Erosion - high energy
  1. hydraulic action
  2. abrasion
  3. solution
C. Transport - variable energy
  1. mechanisms
    1. bed load - rolling or saltation
    2. suspended load
    3. dissolved load
  2. measurement
    1. competence - largest piece stream can carry
    2. capacity - amount of sediment a stream can carry
D. Deposition - low energy
  1. delta - stream meet calm water (usually ocean)
  2. alluvial fan - abrupt change in gradient
  3. flood plain
  4. levee
  5. meandering stream - point bar
  6. braided stream - longitudinal bar
E. Landscape
  1. drainage basins
  2. base level
