Soil Water Remediation Models

[Marty Goldhaber]

Tom:

The latest issue of Elements magazine has a Workbench add that talks about soil water remediation models and mentions partially to fully saturated media. Is there an example somewhere that illustrates that capability. I am interested in the effect of water table on pyrite oxidation in a soil profile.

Hi Marty:

 

There's a couple places you can go. First, in the GWB Reactive Transport Modeling Guide:

 

• 
   
  
• Page 17 tells you how to configure unsaturated media
  
• Page 40 gives you a simple model of weathering within a soil profile in the presence of a CO2 gas buffer
  

 

Second, you can get more detailed information by reading section 27.2 in Craig's Geochemical and Biogeochemical Reaction Modeling textbook.

 

I hope that helps,

 

Tom
