Description UNCERT is a public domain uncertainty analysis and geostatistical software 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 are: Array: An utility for performing mathematical operations on one, two, or a series of 2D or 3D grids. Block: A visualisation 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. 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 Whisker 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 2.5D visualisation tool for viewing 2D grids as a surface. Colour 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 modelling experimental semivariograms. All the program modules use a Graphical User Interface (GUI) with pull-down menus, pop-up dialogues, and when appropriate graphic windows. The UNCERT User's Manual is on-line and downloadable.
