ZONECONC

                     U.S. Geological Survey

ABSTRACT

The computer program, called ZONECONC, tabulates concentration data using the results
from the U.S. Geological Survey Modular Three-Dimensional Ground-Water Flow and
Solute-Transport Model (MODFLOW-GWT). ZONECONC uses concentration data saved by
MODFLOW-GWT in order to tabulate concentration-data statistics by zones of a
ground-water-flow model. Zones are three-dimensional volumes of a flow model that
are designated by zone numbers. The user assigns a zone number for each cell in the
model either interactively by rectangular blocks or from an externally created zone file.
ZONECONC allows for post processing of concentration data from MODFLOW-GWT in a quick
and easy manner by tabulating zonal statistics to identify trends in concentrations.
