Our goal is an incremental approach towards illustrating groundwater contamination in a confined aquifer. The confined aquifer, viewed between wells 1 and 8, offers an environment within the groundwater simulator with the fewest variables. The first 3 experiments are an effort to illustrate the behavior and underlying science that must be understood and demonstrated in the final experiment.

  • Experiments
    • Diffusion
      • Show diffusion without groundwater movement.
    • Flow Rate
      • Show the leading edge of groundwater contamination as a indicator of flow rate (related to section 5 and 13 in manual)
    • Contaminant Plume Length
      • Determine whether contaminant plume length is affected by flow rate for a given amount of dye
    • Illustrate laminar flow in a confined aquifer (Activity 7-1)
      • Show laminar flow between wells 1 and 8.
  • Computational Tools
    • NetLogo
      • + Visualization built in
      • + Agent and cell based simulation structure built in
      • - Possible limitation on world size / agent count in RAM
      • - Possible run time slower than groundwater simulator at higher flow rates
      • - Not parallel
    • Python and MYMPI
      • + Parallelizable
      • + Faster than NetLogo in serial code ?
      • + Visualization software exists
      • - Visualization software must be integrated
      • - MYMPI is untested
