What's new in MODFLOW and MT3DMS

3PM-5PM, June 2, 2013


There is a lot going on with MODFLOW!
Come and learn about new MODFLOW-2005 capabilities..

Click here to register.



This course provides an overview of the following new MODFLOW capabilities.

  • Newton (NWT) version with the Upstream Weighting (UPW) and Unsaturated Zone Flow (UZF) package that together allow perched layers to form within the unsaturated zone and affect the distribution and timing of recharge to the saturated zone
  • Surface-Water Routing (SWR) process that supports simulation of estuaries and swamps.
  • Unstructured Grid (USG) version that supports unstructured grids in part of all of a modeled domain.
  • Local grid Refinement (LGR) version capabilities now allow SFR-represented streamflow and MODPATH-LGR particle to travel between regional and local structured grids
  • MODPATH-OBS that supports the use of quantities such as water age, time of travel, location of flow paths, and fractional contributions for different sources as observations and predictions
  • Farm (FMP) version that integrates more recent developments such as NWT/UPW, PCGN, SWR1, SWI1, LGR, etc

We will also discuss ongoing efforts (many include MT3DMS!) and seek comments from attendees.



This course is designed for anyone interested in new capabilities in MODFLOW and MT3DMS.



All computer program documentation is available on the web. A list of new capabilities and associated developers will be provided in class.



MARY C. HILL, is a senior research scientist with the U.S. Geological Survey in Boulder, Colorado. She has authored over 120 reports and articles. She focuses on using models and data to understand natural environmental systems through sensitivity, calibration, and uncertainty methods. She co-authored UCODE, MODFLOW-2000, UCODE_2005, OPR-PPR, and MMA. She has experience modeling saltwater intrusion, groundwater supply, stream interaction, regional groundwater flow and transport, and integrated hydrologic systems. She has taught semester and short courses for 30 years. Dr. Hill holds a PhD in Civil Engineering from Princeton University.

MATTHEW TONKIN, is a partner at S.S. Papadopulos & Associates, Inc., and. He has focused on the management of environmental data gathering efforts, data synthesis, and the application of models to support decision-making. He provides modeling support and oversight at several large fuel-spill sites, is a member of the Interstate Technology and Regulatory Council (ITRC) MTBE Team, and instructs at the "MTBE and TBA Comprehensive Site Assessment and Successful Groundwater Remediation" workshops organized by ITRC. Matt has completed contracts to the USGS, USEPA, and California Department of Water Resources in the areas of contaminant transport, model calibration and predictive uncertainty analysis. He co-teaches calibration and uncertainty analysis courses with John Doherty (author of PEST and coauthor of the JUPITER API) and hosts a model calibration technical support forum. Dr. Tonkin holds a PhD from the University of Queensland.

Other MODFLOW developers will be in attendance as their schedules allow.

The Colorado School of Mines is located in Golden, which is 20 minutes west of Denver, 1 hour west of the Denver International Airport and can be reached by taxi, airport shuttle or rental car. It is strongly recommended that for events held on the CSM campus, attendees select accommodations within .5 miles of the campus if a rental car or personal transportation will not be available, as taxi service and public transportation from other areas may involve significant delays and costs. Lodging is available in Golden, within walking distance of the campus.

Denver Shuttle Service from Denver Airport

Rental Cars

All Rental car companies at DIA are located on airport property but are away from the main terminal. Each rental company provides a courtesy shuttle to and from Jeppesen Terminal from their locations. All courtesy shuttles pick-up and drop-off from Jeppesen Terminal Level 5, Island 4, outside doors 505-513 (east side) and 504-512 (west side). If you are arriving in Denver, please follow the overhead signage for the appropriate pick-up location, or check-in at your company's counter in the center of the Terminal.

Taxis are readily available and service within the eight counties that make up the Denver metro area. Some companies may also provide service to other destinations within the state of Colorado. Check with your cab company of choice (or directly with your driver at the airport) for more information on fares and destinations served. Fares to Golden area are based on the taxi’s meter and it costs about $70-85 plus the $3.75 airport access fee.
