Terms to learn are in BOLD  in the outline below:


Topic outline:

  1. Hydrologic cycle
  2. Drainage basin (watershed)
    1. Stream valley
    2. Drainage divide
    3. Drainage patterns - dendritic, radial, rectangular, trellis
  3. Stream processes
    1. Streamflow
      1. Factors affecting streamflow velocity
      2. Stream gradient
      3. Stream discharge
      4. Competence versus Capacity
    2. Erosion
    3. Transportation
      1. Stream load - bed, suspended, dissolved
    4. Areas of deposition  - delta, alluvial fan, point bar, natural levee
  4. Stream evolution
    1. V-shape
    2. Base-level
    3. meandering - oxbow lake

When you are finished with this topic, you should be able to answer these questions:

  1. What is the hydrologic cycle?
  2. What factors influence the velocity of a stream?
  3. What is stream gradient and how does it change over the longitudinal stream profile?
  4. What are the types of stream load?
  5. What is the difference between a delta and an alluvial fan?
  6. How are oxbow lakes formed?
  7. How are floodplains formed and what are natural levees?
  8. What controls how far down a stream erodes?
