What's new in GWD version 6?

The Version 6 release introduces several powerful new tools and significant improvements to existing workflows. Below are the most important additions to the GWD suite:

• 🆕 Gradient Vector Map
  A brand-new visualization tool for displaying flow direction and magnitude.
  • Universal Compatibility: Supports gradient vectors for KT3D_H2O outputs and any regular grid rasters.
  • Symbology: Choose between 2D Arrows or 3D Cones to suit your model's depth.
  • Dynamic Styling: Color symbols by Azimuth (direction) or Magnitude (intensity), and easily control vector density and size for clean, professional maps.
• 🆕 Theis Grid

  Theis Grid is a specialized analytical modeling tool designed to rapidly simulate transient groundwater level changes. It bridges the gap between simple manual calculations and complex numerical models like MODFLOW.

  • Model Pumping Impacts: Calculate cumulative drawdown or mounding from an unlimited number of extraction and injection wells on independent schedules.
  • Regional Trends: Superimpose transient well effects onto a planar regional surface, accounting for natural E-W and N-S hydraulic gradients.
  • High-Resolution Surfaces: Generate hydraulic head rasters for immediate 3D visualization.
  • Capture Zone Analysis: Use resulting surfaces to calculate particle tracks—essential for remediation and water rights management.
• 🆕 Three-Point Gradient

  Determine the groundwater flow direction and gradient by fitting a planar surface to three selected data points (e.g., monitoring wells). The tool calculates the potentiometric slope and generates a vector arrow indicating the flow direction.

• 🆕 Simulated Time Series

  Extract and visualize simulated data directly from MODFLOW or MT3D models. This tool retrieves calculated values—such as heads, concentrations, or drawdowns—at specific X, Y, and Layer locations across the entire simulation duration.

• 🆕 Zone Budget

  GWD now provides a streamlined interface for the USGS ZONEBUDGET utility. This integration offers an intuitive workflow for defining model zones and a robust graphical interface to execute, analyse and visualize sub-regional water budgets.

• 🆕 MODFLOW-USG Well Flow Reduction

  GWD now fully supports flow reduction outputs from the MODFLOW-USG Well (WEL) Package. If the AUTOFLOWREDUCE option is active in your model, GWD can extract and visualize exactly how pumping rates were adjusted by the solver.

• 🆕 Expanded Boundary Condition Outputs

  Visualize binary outputs for MAW, SFR, and LAK packages. GWD now supports both stage/head data and cell-by-cell flow budget terms for these advanced packages.
