Compatible Hydrogeologic Software Offerings

Waterloo Hydrogeologic offers intuitive and helpful 3rd party software that elevates and strengthens your project results.

MODFLOW-SURFACT

  • MODFLOW-SURFACT Flow and Transport groundwater simulation software features many robust methods and enhanced simulation capabilities for handling complex saturated/unsaturated subsurface flow and transport processes. Based on the USGS modular groundwater flow model, MODFLOW.

Golden Software

  • Golden Software is a scientific graphics software company that has a long-standing partnership with Waterloo Hydrogeologic.  Golden Software have developed applications which can be used by our clients to enhance the models created using Waterloo Hydrogeologic’s Visual MODFLOW Flex.

MODFLOW-SURFACT

MODFLOW-SURFACT™ is one of the most comprehensive flow and transport models available. Built around the MODFLOW code, MODFLOW-SURFACT includes advanced computational modules that are based on robust, efficient, mass-conserving algorithms making it faster and more accurate than its transport modeling counterparts.

  • Handles complete desaturation and resaturation of grid cells
  • Accurate delineation and tracking of water table position, taking into account flow in the unsaturated zone, delayed yield, and vertical flow components.
  • Automatic and correct redistribution of the total flow rate of a well screened through multiple model layers when the upper cell(s) are pumped dry.
  • Accommodation of wellbore storage and overpumped wells and prevents water table buildup beyond a specified recharge-ponding elevation.
  • Adaptive time-stepping schemes automatically adjusts time-step size to the non-linearities of the system to optimize the solution stability.
  • Capability of modeling unsaturated water or air movement.
  • Enhanced Newton-Raphson linearization option increases robustness for unconfined and/or unsaturated flow conditions.

 

 

UnSat Suite and UnSat Suite Plus

UnSat Suite and UnSat Suite Plus simulate one-dimensional flow and groundwater contaminant transport through unsaturated zones.  UnSat Suite includes:

  • SESOIL – a popular US EPA model which is capable of simultaneously modeling water transport, sediment transport and pollutant fate.
  • PESTAN – a model for assessments of groundwater contamination by pesticide used in agricultural practice.
  • VS2DT – a finite difference numerical model for determining the fate of agricultural chemicals, landfill leachate, and accidental chemical spills in the unsaturated zone.
  • VLEACH – a model for evaluating the fate of volatile organic contaminants in the unsaturated zone.

UnSat Suite Plus also includes:

  • HELP – a finite difference model used to evaluate the hydrologic performance of landfills containing multiple layers and different layer combinations.
