Data WorksheetSurfer includes a full-featured worksheet for creating, opening, editing, and saving data files.
Object ManagerDisplays all the objects in the document in an easy-to-use hierarchical tree arrangement.
Visual HELP, the international standard for modeling landfill hydrology and estimating groundwater recharge rates.

Software for Optimization of Hydrologic Landfill Design – Based on HELP

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. * Note: Network Licenses are not available for this product.

Overview

Visual HELP combines the latest version of the HELP model with an easy-to use interface and powerful graphical features for designing the groundwater model and evaluating the modeling results. Visual HELP uses the latest technologies in software engineering to introduce many new methods for:

  • Visualizing and managing your projects
  • Generating input data, presenting modeling results
  • Sharing data between models

This completely-integrated modeling environment you to:

  • Graphically create several profiles representing different parts of a landfill,
  • Automatically generate statistically reliable weather data for virtually any location in the world (or create your own)
  • Run complex model simulations
  • Visualize full-color, high-resolution results
  • Prepare a summary document (tables and graphs) for your report

Product Overview

Main FeaturesThe Visual HELP groundwater package features numerous tools and design elements that enable you to produce professional visualizations.
Visual Help InterfaceVisual HELP utilizes a very ‘flat’ interface structure and innovative graphical tools to give you convenient access to both the basic and advanced features of the HELP model.
Creating A ProjectThe logical structure of the Visual HELP interface facilitates a very quick learning curve that allows you to generate and modify a typical profile in just minutes.
Weather GeneratorThe Weather Generator is a built-in component for generating statistically reliable weather for virtually any location in the world for periods of up to 100 years. This powerful tool utilizes a database of more than 3000 international weather stations containing historical climatological data for each location.
Displaying & Documenting Modeling ResultsVisual HELP gives you all the graphical tools that you need to properly analyze and interpret the results and to produce report-quality figures and summaries of data.

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.

Advanced Groundwater Flow and Transport Modeling Software based on MODFLOW

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.

Benefits of MODFLOW-SURFACT

  • 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
  • Prevents water table buildup beyond a specified recharge-ponding elevation
  • Handling of seepage face boundary conditions
  • Adaptive time-stepping schemes automatically adjusts time-step size to the non-linearities of the system to optimize the solution stability
  • Robust and efficient Pre-conditioned Conjugate Gradient matrix solver
  • Capability of modeling unsaturated water or air movement
  • Enhanced Newton-Raphson linearization option increases robustness for unconfined and/or unsaturated flow conditions

Recent Additions

  • The powerful PCG5 solver add-on is up to 20 times faster than the PCG4 solver thanks to its advanced computational techniques
  • The Recharge Package (RSF4) has been modified to include zonal input of recharge with zonal recharge values provided via a separate recharge time-series (RTS) file that is independent of the stress-period setup for varying boundary conditions
  • The Evapotranspiration (ET) packages EVT and ETS1 (referred to as ET2 in MODFLOW-SURFACT) have been modified to include zonal input of ETmax values provided via a separate ET time-series (ETS) file that is independent of the stress-period setup for varying boundary conditions
