C44 TOXIC SORPTION OPTION, DIFFUSION AND MIXING

*

* NTOXN: TOXIC CONTAMINANT NUMBER ID (1 LINE OF DATA BY DEFAULT)

* ISTOC: 0 INORGANIC SOLIDS BASED PARTITIONING ONLY (Kd APPROACH)

*              1 FOR DISS AND PART ORGANIC CARBON SORPTION, POC IS SPECIFIED

*              2 FOR DISS ORGANIC CARBON SORPTION AND POC FRACTIONALLY

*                 DISTRIBUTED TO INORGANIC SEDIMENT CLASSES

*              3 FOR NO DISS ORGANIC CARBON SORPTION AND POC FRACTIONALLY

*                 DISTRIBUTED TO INORGANIC SEDIMENT CLASSES

* DIFTOX: DIFFUSION COEFF FOR TOXICANT IN SED BED PORE WATER (m^2/s)

* DIFTOXS: DIFFUSION COEFF FOR TOXICANT BETWEEN WATER COLUMN AND

*                  PORE WATER IN TOP LAYER OF THE BED(m^2/s)

*                 > 0.0 INTERPRET AS DIFFUSION COEFFICIENT (m^2/s)

*                < 0.0 INTERPRET AS FLUX VELOCITY (m/s)

* PDIFTOX: PARTICLE MIXING DIFFUSION COEFF FOR TOXICANT IN SED BED (m^2/s)

*                  (if negative use zonal files PARTMIX.INP and PMXMAP.INP)

* DPDIFTOX: DEPTH IN BED OVER WHICH PARTICLE MIXING IS ACTIVE (m)
