A computer program for the analysis of 1-D contaminant migration through a soil layer

The physical and chemical processes that influence contaminant transport through a saturated soil layer are presented. The computer program (1DContr) was developed based on existing analytical solutions for one-dimensional transport of contaminants in a saturated soil layer. The computer program is given for pulse and continuous source. The formulation includes advective and dispersive transport as well as sorption and first order transformation. The computer program that is based on analytical solutions is recommended for preliminary design.
