PHT3D benchmark problems:

PHT3D has been tested for a range of benchmark problems from the literature. Those form the Examples 1-9 in the current user's manual. The MODFLOW96 (w. LKMT2 interface) and PHT3D input files for these examples can be downloaded here.   

• Example 1: Single species transport with monod kinetics
• Example 2: Migration of mineral dissolution/precipitation fronts
  
• Example 3: Migration of redox fronts
• Example 4: Transport and cation exchange
• Example 5: Artificial recharge: Transport and cation exchange
• Example 6: Transport, precipitation/dissolution and cation exchange
• Example 7: Multiple species transport with kinetic, sequential/parallel degradation
• Example 8: Multiple species transport with sequential, kinetically controlled biodegradation of chlorinated hydrocarbons
• Example 9: Multiple species transport and biodegradation of hydrocarbons
