VIRALT
Category Contaminant transport (2D analytical)
Platform DOS
Status Public domain
Description VIRALT is a modular semi-analytical and numerical code that simulates the transport and fate of viruses in ground-water. The code provides both steady-state and transient transport analyses taking into account the major physical processes including: advection and dispersion of viral particles in the vertical dimension in the unsaturated zone and along ground-water pathlines in the saturated zone; adsorption; and inactivation (die-off). Contaminant sources of various shapes can be handled. Both areal and line sources in unconfined or confined aquifers can be accommodated. Typically, areal sources may be used to represent leaky septic tanks, cesspools or areas of surface and subsurface disposal of waste water. Line sources may be used to represent leaky sewer lines or pipes. Barrier or steam boundary conditions which exist over the entire aquifer depth can be simulated. Data input and output are facilitated by a menu-driven interface with help screens. Graphical output can be sent to a pen plotter or printer, or saved in HPGL.
