Groundwater Modelling Software

DHI's finite-element groundwater platform — unstructured meshes, density-driven flow, heat and mine dewatering.

The Python interface to MODFLOW — build, run and post-process groundwater models entirely in code.

Veteran commercial MODFLOW GUI with deep PEST integration — a consultant favourite for calibration-heavy work.

The standard for vadose-zone modelling — variably saturated flow and transport by Richards' equation.

DHI's integrated hydrological model — coupled overland, unsaturated, groundwater and channel flow.

The USGS groundwater model — the world standard for aquifer simulation, rebuilt as a modular multi-model framework.

USGS particle tracking for MODFLOW — pathlines, travel times and capture zones from flow solutions.

Multi-species solute transport for MODFLOW — advection, dispersion, sorption and reactions in aquifers.

The USGS's free graphical interface for MODFLOW — grid-independent model design without a commercial GUI.

Model-independent parameter estimation and uncertainty analysis — the calibration standard for groundwater models.

USGS geochemical modelling — speciation, batch reactions, 1D reactive transport and inverse modelling.

Time-series analysis of groundwater heads in Python — transfer-function models instead of full aquifer simulation.

Analytic element groundwater modelling in Python — multi-layer steady flow with no grid at all.

Python framework for PEST/PEST++ workflows — programmatic setup, ensembles and uncertainty analysis.
