Fluvial Processes


I.   BASIC CONCEPTS AND TERMINOLOGY

A.   Foundational Terminology

  1. perennial vs. intermittent vs. ephemeral
  2. alluvium, alluvial soils
  3. thalweg ➡ political borders?
B.   Stream Systems
  1. drainage basin/watershed ... photo
  2. Stream Patternssecond example

II.   EROSION AND DEPOSITION

A.   Erosion

  1. entrainment ... aerial view
  2. splash ... animation
  3. sheet
  4. rill
  5. gully
B.   Abrasion and Corrosion

C.   Transportation: saltation and traction   (video)

D.   Key Relationship

  1. increase volume -> velocity -> turbulence = erosion  (photo 1) (photo 2)
    (decrease volume -> velocity -> turbulence = deposition)
E.   River Channel Changes
  1. deepening
  2. widening
  3. lengthening

III.   LANDFORMS AND REJUVENATION

A.   Flood Plain Features   (diagram)

  1. bluff
  2. natural levee (photo)
  3. ox bow lake ... and here
  4. meander scar (or here)
  5. braided channel (example 1) (example 2)
B.   Stream Rejuvenation (Cycles)
  1. uplift -- downward cutting... entrenched meanders
  2. gorge
  3. stream capture (animation)
