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.

For gunzip'd and tar'd (i.e., bundled & compressed) Unix
files, please use
- $ gzip -dc [file.tar.gz] | tar xvf -
to uncompress & restore directories/files.
If you don't have GNU 'gunzip'
installed in your system, please download GNU gzip program
(GNU gzip 1.2.4 (tar file)) first, then
