Selected Groundwater Activities at the U.S. Geological Survey With - PowerPoint PPT Presentation

Selected Groundwater Activities at the U.S. Geological Survey With focus on opportunities for NIWR science William L. Cunningham Senior Science Advisor for Groundwater Chief, Office of Groundwater U.S. Geological Survey Reston, VA National Institutes for Water Resources Annual Meeting February 27, 2917 Washington, D.C. U.S. Department of the Interior U.S. Geological Survey

Today’s 3 Topics • NGWMN (Data are fundamental) – Actively looking for NGWMN collaborators and partners (or just outside research) to apply these data • GW/SW Exchange – Ongoing focus on these issues. Geophysical, geochemical, and modeling studies at many scales. Also improving robustness of field methods. • GW Modeling software – GW/SW Integration, with demand and/or appropriation drivers – Highlight upcoming product – MODFLOW6 – All “Applications” of USGS GW modeling now publically available on http://Data.Gov • For more information – A monthly newsletter as a way to be notified of USGS groundwater studies, new software, and model applications.

GW/SW Exchange Video Example: GW discharge into SW (FLIR) (Briggs and others, 2015)

Modeling Tools: GSFLOW Simulation Of All Major Hydrologic Processes GSFLOW integrates MODFLOW-NWT and PRMS (Markstrom and others, 2008)

Flow and Transport: MT3D-USGS • Updated version of MT3D with support for – MODFLOW-NWT – Unsaturated Zone Flow (UZF) Package – Stream-Flow Routing (SFR) Package – Lake (LAK) Package – Contaminant Treatment System (CTS) Package – GW age and temperature (Bedekar and others, 2016)

New Capability: Streamflow Transport (SFT); Lake Transport (LKT) • 1D transport in stream • Instantaneous mixing in lake (Bedekar and others, 2016)

Coming Soon: MODFLOW6  GW issues becoming more complex  Proliferation of new versions and packages  Increase in package complexity  Loss of package independence  Incompatibilities  Difficult to add other process models to MODFLOW; same grid required for all packages and processes 6 th Version 1984 1988 2000 2005 1996

MODFLOW6 Objectives • Consolidate – Combine best functionality from existing MODFLOW versions – Exclude duplicate and outdated functionality • Improve – Achieve fast and reliable answers for highly coupled systems – Modernize program design and simplify input/output structure • Extend – Introduce modular “model” concept, similar to modular “packages” concept or original design – Opportunities for linking with other models will…. • Extend MODFLOW to a hydrologic simulator
