Tentative MODFLOW 6 Development Plans

Last updated September 8, 2021

MODFLOW 6.3.0 (Fall 2021)

• Release the Interface Model approach for coupling through exchanges
• Node Property Flow (NPF) Package enhancements for the GWF Model
• • Variable Hydraulic Conductivity with Depth (VKD) Capability
• • Time-Variant Hydraulic Conductivity (TVK) Capability
• Storage (STO) Package enhancements for the GWF Model
• • Variable Storage with Depth (VSD) Capability
• • Time-Variant Storage (TVS) Capability
• SFR n-point cross section as alternative to rectangular channels

MODFLOW 6.4.0 (Early 2022)

• Parallelization of multiple coupled models using the Message Passing Interface (MPI)
• Particle Tracking (PRT) Model for structured and unstructured grids

Miscellaneous Ongoing Efforts

• Creating packages from memory
• Conductance recalculation as needed
• Condense advanced package functionality into parent class
• Alternative READASARRAYS input for MAW, SFR, LAK, UZF
• Buoyancy Package with static density array
• Agricultural Demand (AG) Package (or possible API link with other models)

Other efforts (perhaps MODFLOW 6.5.0)

• Groundwater Heat Transport Model
• Richard's equation
• Linear Network Flow Model
• Save state mechanism
• Revised file input/output
