MASCOT computes the two- and three-dimensional space-time dependent, convective-dispersive transport of a four-member radionuclide decay chain in unbounded homogeneous porous media for constant (step and band) and radionuclide-dependent release. A steady-state isothermal groundwater flow regime is assumed with parallel streamlines along the direction of flow. The solutions are designed for an unbounded medium flow field assumed to be semi-infinite normal to the source and infinite orthogonal to the source with a variety of boundary conditions, including a single or multiple finite line source or a Gaussian-distributed source in the two-dimensional case, and a single or multiple patch source or bivariate-normal distributed source in the three-dimensional case. A postprocessor program, MAS-GRF, which produces tables and/or graphs from MASCOT output, is included.

• Resource Relation: Other Information: DN: The MAS-GRF postprocessor requires the proprietary CA-DISSPLA 10.0 software to produce graphical results. MAS-GRF can produce tables if DISSPLA is not available. Both MASCOT and MAS-GRF must be compiled using the FORTRAN compiler option, G-FLOATING, which implements extended-range floating-point arithmetic. Other non-standard FORTRAN 77 features include extended-length symbolic names, the END DO statement, and calls to system DATE and TIME routines.; PBD: 29 Mar 1989
