There have been six major releases of the core MODFLOW version: MODFLOW-84, MODFLOW-88, MODFLOW-96, MODFLOW-2000, MODFLOW-2005, and MODFLOW 6. These advanced MODFLOW versions are also available from the USGS. Advanced MODFLOW versions include specialized MODFLOW variants and versions of MODFLOW that use newer formulations. MODFLOW 6 is presently the core MODFLOW version distributed by the USGS, but MODFLOW-2005 (the previous core version) is still actively maintained and supported. The core MODFLOW version is the one that is under active development and is often the most widely used and most thoroughly tested version. There is a core MODFLOW version, which is developed and maintained by the USGS Water Mission Area, and there are advanced versions.

This page focuses on MODFLOW versions that are part of USGS water enterprise software that is funded, developed, and maintained by the USGS Water Resources Mission Area. The USGS releases multiple versions of MODFLOW. Users are encouraged to track MODFLOW developments through our version-controlled MODFLOW 6 repository. The USGS plans to continue these development efforts to meet the needs of the USGS, our stakeholders, and the needs of the hydrologic modeling community. In addition to these ongoing efforts, future efforts may include development of new surface water, pipe network, and heat transport models. This new parallelization capability is being developed in a general manner that can be easily extended for future MODFLOW model types (for example GWT) applied at local, regional, and continental scales and can be used on desktops and HPC systems. Preliminary versions of MODFLOW 6 with this new capability have been used to solve groundwater models with billions of model cells.

Parallelization of the MODFLOW 6 multi-model framework for High-Performance Computing (HPC) using the Message Passing Interface (MPI).

Extension of MODPATH to track particles in MODFLOW 6 models that use Discretization by Vertices (DISV) and fully unstructured (DISU) grids.

This new BUY Package makes it possible to simulate problems related to saltwater intrusion, deep-well injection, aquifer storage and recovery, and brine migration.

A new Buoyancy (BUY) Package that extends the Groundwater Flow (GWF) Model of MODFLOW 6 to represent variable-density groundwater flow.

A Groundwater Transport (GWT) Model that works with structured or unstructured grids, the Newton formulation, and the advanced stress packages available in MODFLOW 6.

A Basic Model Interface (BMI) for MODFLOW 6 to support easier coupling with other models such as those that simulate groundwater recharge, geochemical mixing, and optimization and management, as well as models that would benefit from tight coupling.

Current development efforts are focused on adding new capabilities to MODFLOW 6.

Ongoing efforts include providing maintenance and support for existing versions of MODFLOW such as MODFLOW 6, MODFLOW-2005, MODFLOW-NWT, MODFLOW-USG, MODPATH, MT3D-USGS, and related and supporting programs such as FloPy and PEST++. The USGS Water Mission Area actively develops and supports the MODFLOW suite of programs. The family of MODFLOW-related programs now includes capabilities to simulate coupled groundwater/surface-water systems, solute transport, variable-density flow (including saltwater), aquifer-system compaction and land subsidence, parameter estimation, and groundwater management.

Originally developed and released solely as a groundwater-flow simulation code when first published in 1984, MODFLOW's modular structure has provided a robust framework for integration of additional simulation capabilities that build on and enhance its original scope.
