This is a detailed description of one experiment listed on the CS382 course page



  • enVision sand and gravel groundwater simulator
  • water soluble dye
  • pipette
  • water
  • ruler
  • kitchen timer or some other time measurement device


  1. Mark ruler on outside of case
  2. Choose flow rate and dye amount
  3. Contaminate the confined aquifer
  4. Measure plume length at 10 second intervals

repeat with varied flow rate, recording length at each interval


  1. Find mean / max plume length for flow rates

Considerations for a Computer Based Simulation

  1. units - accurately moving from our metric world to pixels
  2. flow rate - how to control?
