Covers the fundamentals: Darcy's law, governing equations, conceptual model development, boundary conditions, model execution, calibration, and contaminant transport. Uses IGW-NET as the vehicle for teaching groundwater science — complementary to the Users' Reference Manual, which focuses on the platform itself.
Comprehensive 22-chapter reference covering the full modeling workflow — applicability, domain setup, aquifer attributes, vertical layering, boundary conditions, calibration, stochastic methods, and 33 common pitfalls with interface-based diagnostic recipes. Where Pinder's Beginner's Manual teaches the science, the Users' Reference Manual teaches the platform.
Progressive skill-building — from your first 2D model through Monte Carlo uncertainty, 3D visualization, T-PROGS geology, and DataNET integration.
Deep-dive standalone articles on specific concepts — understand the why behind modeling choices, not just the how.
Real-world modeling projects walked through end-to-end — concept model, data sourcing, simulation, calibration, interpretation. See how experienced modelers approach full projects.
150 per-element reference pages — every IGW-NET UI component, organized hierarchically for fast lookup.
IGW-NET is built on the USGS MODFLOW family — the international standard for groundwater modeling. These are the authoritative reference manuals and software pages for each engine, hosted by the U.S. Geological Survey.
Trained on all six documentation pillars. Answer workflow questions, interpret errors, point you to the right dialog or chapter.
