| Pesticide Root Zone Model-2 (PRZM2) provide a deterministic simulation of the fate of agricultural pesticides in the crop root and underlying unsaturated zone. |
| PRZM2 can simulate multiple pesticides or pesticide parent-daughter product relationships, and estimate probabilities of concentrations or fluxes in or from various media to perform exposure assessments. PRZM2 consists of two subordinate models, PRZM (Pesticide Root Zone Model)/VADOFT (Vadose Zone Flow and Transport) that are linked in PRZM2 using an execution supervisor that can build loading modules tailored to site-specific situations. Code is equipped with Monte Carlo pre- and post-processor to perform probability-based assessments. PRZM is a one dimensional, dynamic, compartmental model that can be used to simulate pesticide movement in unsaturated soil systems within and immediately below the plant root zone. PRZM has two major components: hydrology and solute transport. |
Unix Version Specification
| This version of PRZM2 model is designed for the Unix family of workstation, mainframe, and/or compatible systems (refer to DEVELOPMENT SYSTEM). There are no hardware specific commands, options, and/or FORTRAN statements within the PRZM2 model system. It has been compiled, linked, and executed under a variety of Unix hardware and software platforms. It should be compatible with any standard hardware/software platform running Unix variants. For further compilation and linking information, refer to the DEVELOPMENT SYSTEM section. |
