This course introduces ground-water professionals to numerical modeling. The basic modeling concepts covered include using MODFLOW-2005 for

  • conceptual model development,
  • definition of boundary and initial conditions,
  • parameter specification,
  • spatial discretization,
  • time stepping, and
  • solution control

Basic modules of MODFLOW are explained and concepts are reinforced with hands-on exercises, and additional modules of MODFLOW are described. 

Course sessions are from 8:00 AM to 5:00 PM.

Participants should bring their own laptop computer with the Windows XP or later operating system.



The course begins with discussion of the phases of a modeling project, followed by presentation of concepts related to:

  • conceptual model development,
  • definition of boundary and initial conditions,
  • parameter specification,
  • finite-differencing,
  • gridding,
  • time stepping, and
  • solution control.
Soon thereafter, hands-on sessions begin with a simple problem using text-based interfaces. Gradually, subsequent exercises use more MODFLOW packages, develop a more complex model, and evaluate transient situations.

The exercises continue with a discussion of, introduction to, and use of graphical user interfaces. The course emphasizes use of text files. If you have the ability to look in, and understand the content of these files or control these commands, you will be a valuable modeler. Inevitably, in your project work, something does not work correctly in a GUI and you need to track down and resolve the problem. Or, you want to do something unique with your project that the GUI developer hadn't planned on. If you do not understand the file structure and commands, you cannot move forward, and your project is in jeopardy. This is why the course emphasizes the use of text files, but uses GUIs to facilitate visualization.

Brief lectures between exercises discuss results of the previous exercise, potential pitfalls, and set the stage for the subsequent exercise.

Every project is unique. Modeling requires fundamental understanding of modeling concepts applied to each specific situation. Approaches to resolving such model-specific problems are discussed. Attendees who are already working on a modeling project are encouraged to bring questions.



This course is designed for hydrogeologists, environmental engineers and resource managers familiar with ground-water flow concepts, but who have limited or no experience with ground-water flow modeling.



Attendees will receive course notes, MODFLOW 2005 software as well as pdfs of their basic manuals.



This course will be taught by Drs. Suzanne Paschke  and Mary C. Hill. We are grateful to Dr. Eileen Poeter for sharing materials upon which this course is constructed. Biographies are listed in alphabetical order.

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.

SUZANNE PASCHKE, is a section chief in the Colorado Water Science Center of the U.S. Geological Survey. She has completed studies of the Denver Basin and other aquifer systems. Dr. Paschke holds a PhD from the Colorado School of Mines.



The fee for the short course is $745 by 4PM Mountain Daylight Time, May 19, 2013 ($845 after May 19).  You will be invoiced for the tuition balance. The fee covers instruction, course notes, refreshments, and continuing education units. Lodging and meals are not covered. Payment in full must be received prior to the beginning of the course. The registration fee may be paid by check, VISA, MasterCard, AMEX, Discover or purchase order (US Only). A maximum of 20 applicants will be able to attend the course due to space limitations.

If cancellation is made before May 19, 2013, tuition will be refunded except for the $100 deposit. Cancellations made after that date will forfeit a $150 processing fee in addition to the $100 deposit. In case of cancellation, the right to course material is forfeited. Substitutions are permitted at any time prior to the start of the course. Please be advised that if the program is cancelled due to insufficient enrollment, Colorado School of Mines will return all course fees, but will not be liable for any other expenses incurred by the prospective attendees.

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

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. Taxis pick-up and drop-off from Jeppesen Terminal Level 5, Island 1, outside doors 507-511 (east side) and 506-510 (west side).
