Modeling/Groundwater Management short course scheduled

A two-day course on constraints for combining modeling and management for groundwater, titled “You got chocolate in my peanut butter,” is scheduled for Oct. 15-16, 2007, in Austin. Dr. John Doherty, James Rumbaugh and Dr. Steve Young are featured speakers.

The course, sponsored by The University of Texas at Austin Jackson School of Geosciences, Texas Water Development Board (TWDB) and URS Corporation, is free but attendees must register. To register, contact Pam Bradley at and for questions about the course, contact Steve Young at 512.419.5076 or

The course will cover approaches for establishing groundwater modeling objectives, constructing and calibrating groundwater modes and estimating the uncertainty in model predictions. The course will present applications of Groundwater Vistas, commercial software adopted for use by TWDB for generating and visualizing groundwater model results, and of PEST, free software that provides advanced methods for model calibration and quantifying predictive uncertainty. The course will present different model calibration approaches and explain benefits associated with using parameter-estimating codes like PEST to calibrate models. The course will also present sources of model uncertainty and demonstrate how PEST can be used to estimate uncertainty in predicted drawdowns, groundwater fluxes, water budgets and hydraulic heads.

The course is for modelers, managers and policy makers interested in understanding potential benefits of using models in addressing groundwater management issues and constraints that can limit the utility of models. Attendees should have a basic understanding of hydrogeology. The course will help modelers determine whether they are developing models useful to decision makers and will help decision makers work with modelers to develop appropriate modeling objectives.
