Physical Processes

As noted above, knowledge of relevant physical processes will be crucial in modeling practice. It is beyond the scope of the present modeling review to analyze such research critically; rather, appropriate recent work will be summarized in detail.

• NAPL Dissolution
  • Earlier work.
  • Potential causes of nonequilibrium behavior.
  • NAPL blob shapes and sizes.
  • Heterogeneity and LEA validity.
  • Tailing.
  • LEA summary.
  • Equilibrium data.
  • Approximations to dissolution kinetics.
• VOC Mass Transfer
• Capillarity and Hysteresis
