IGW3D User Manual 

IGW3D (IGW Version 8.0.0) is a real-time, interactive and visual software system for unified deterministic and stochastic groundwater modeling.
The current version of the software, characterized by its full interactivity and built-in real-time and animated visualization, has the following distinct capabilities:

• High level and grid-independent conceptual modeling. This includes interactive visual specification and editing of model domain, aquifer properties and stresses (over any arbitrarily-shaped area, at any point in time during the process of model construction), simulation, and analysis.
• Data-enabled modeling built directly on a pre-processed, multiscale “intelligent” database of groundwater
• and environmental data
• Automatic grid generation and conversion of conceptual representation to numerical model(s).
• Interactive simulation and ‘reaL-time' visualization and animation of flow, in response to both deterministic
• and stochastic stresses.
• Interactive, visual, and ‘real-time’ particle tracking, random walk, and reactive plume modeling in both systematically and randomly fluctuating flow.
• Interactive and visual conditional simulation of hydrogeologic and geochemical spatial fields; ‘real-time’, visual, and parallel conditional flow and transport simulations.
• Interactive scattered data interpolation, regression, and variogram modeling.
• Interactive water and contaminant mass balance analysis with visual and real-time flux update.
• Interactive, visual, and ‘real-time’ monitoring of head hydrographs and concentration breakthroughs.
• Real-time modeling and visualization of aquifer transition: confined or unconfined to partially de-saturated, or completely dry and rewetting.
• Interactive, visual, and ‘real-time’ sub-scale modeling using a telescopic approach.
• Interactive, visual, and ‘real-time’ stochastic Monte Car lo simulations.

The user-friendly software system dramatically simplifies the process of groundwater modeling and provides virtually ‘instant’ analysis with visual solution representation. The software provides an effective tool for: 1) Groundwater professionals, site planners, managers, and regulators to conduct site investigation and experiment in ‘real-time’ with sampling strategies, management options, and remedial schemes, 2) Researchers to study field-scale  physical and chemical groundwater processes in heterogeneous soils, and 3) Academics to teach groundwater flow transport, site investigation, and remediation, using vivid interactive and real-time simulations.
