Groundwater flow

We supply software that you could otherwise purchase from organisations like Waterloo Hydrogeologic, HydroGeoLogic, Environmental Systems Inc., Aquaveo, and Scientific Software Group.

How do we define groundwater flow? We distinguish here between flow and transport, i.e. in this category of software, we focus on movement of water rather than dissolved solutes or heat. We also include a number of programs used to analyse pumping or aquifer tests.

Discounts are available for purchasing multiple copies, if the software is to be used for academic/research purposes, and in some case for purchase by government agencies. Please ask us about maintenance, upgrades and combining licences.

Visual MODFLOW® Flex Basic 2014.2 Visual MODFLOW Flex is a sophisticated three-dimensional modeling program for building, calibrating, and evaluating groundwater flow and contaminant transport models, and is based on industry-standard codes such as MODFLOW-2000, MODFLOW-2005, MODFLOW-NWT, Zone Budget, MODPATH, enhanced 3D visualisation, MT3DMS and RT3D*.

Visual MODFLOW Flex includes a conceptual model builder and seamlessly integrates several powerful numerical engines with a graphical user interface that increases modelling productivity and decreases the complexities typically associated with building, calibrating and evaluating three-dimensional groundwater flow and contaminant transport models.

One modelling scenario can be open within a project at any time. The Basic "edition" supports MODFLOW-SURFACT* as an add-on.

Features marked * are only accessibly within the accompanying Visual MODFLOW Classic interface, rather than the new Flex interface.

Visual HELP and Unsat Suite

Package Version Description More information Price
Visual HELP 2.2 Visual HELP is the most advanced hydrological modeling environment available for designing landfills, predicting leachate mounding and evaluating potential leachate seepage to the groundwater table. Please ask $
Unsat Suite 2.2 The UnSat Suite groundwater software product is specifically designed to handle one-dimensional groundwater flow and contaminant transport in the unsaturated zone. This one dimensional model simulates the downward vertical flow of groundwater and migration of dissolved contaminants in the groundwater through a thin column of soil. The package provides access to SESOIL, PESTAN, VS2DT and VLEACH. Please ask $
Unsat Suite Plus 2.2 Combines Unsat Suite with support for HELP. Please ask $
