UNCERT is a public domain uncertainty analysis, geostatistical software, and visualization package.
It was developed for
evaluating the inherent uncertainty in describing subsurface geology, hydraulic properties, and the
migration of hazardous contaminants in groundwater flow systems. The package is well suited for
evaluating hazardous waste sites and evaluating remediation methods, but the package also has many
general modules which are usable by researchers from a wide range of disciplines. The modules included
in UNCERT are briefly described below.
Array: An utility for perform mathmatical operations on one, two, or a series of 2D or 3D
Block: A visualization package for viewing 3D scattered data and 3D finite-difference
(block/rectangular) grids. Block can also do rough volume calculations.
Contour: A 2D contouring and gradient analysis package.
Distcomp: A program for comparing data distributions. Uses histograms, Q-Q, and P-P plots.
Grid: A 2D and 3D gridding program. Inverse-Distance, Simple and Ordinary Kriging, and
Trend-Surface Analysis are supported.
Histo: A utility for doing univariate statistics. Histogram, Box and Wisker Plots, and
Probability Plots are supported.
Mainmenu: A simple menu interface to select the other UNCERT modules.
Modmain: A GUI pre- and post-processor for MODFLOW.
MT3Dmain: A GUI pre- and post-processor for MT3D.
Plotgraph: A X-Y graph utility. Regression also supported.
Sisim: A GUI pre- and post-processor for a Soft Indicator Kriging Simulator.
Surface: A 2-1/2D visualization tool for viewing 2D grids as a surface. Color contouring,
shaded relief, and gradient viewing options available.
Vario: A tool to generate experimental semivariograms (1D and 2D) for irregularly scattered
data, and gridded data.
Variofit: A tool for modeling experimental semivariograms.
All the program modules descibed use a Graphical User Interface (GUI) with pull-down menus, pop-up dialogs, and when approprite graphic windows.
