– Actively looking for NGWMN collaborators and partners (or just
– Ongoing focus on these issues. Geophysical, geochemical, and modeling studies at many scales. Also improving robustness of field methods.
– GW/SW Integration, with demand and/or appropriation drivers – Highlight upcoming product – MODFLOW6 – All “Applications” of USGS GW modeling now publically available
– A monthly newsletter as a way to be notified of USGS groundwater studies, new software, and model applications.

– Combine best functionality from existing MODFLOW versions – Exclude duplicate and outdated functionality
– Achieve fast and reliable answers for highly coupled systems – Modernize program design and simplify input/output structure
– Introduce modular “model” concept, similar to modular “packages” concept or original design – Opportunities for linking with other models will….
