MODFLOW 6 is the current version of MODFLOW released and supported by the USGS. The program is under active development by the short course instructors and the broader hydrologic community. This short course introduces participants to MODFLOW 6 and its growing simulation capabilities. Each topic includes a short lecture on the underlying concepts and implementation followed by a live demonstration. Live demonstrations will use the Python language, Jupyter Notebooks, and the FloPy Package to create, run, and post-process MODFLOW 6 simulations.

The focus of this one-day short course is directed to constant-rate pumping tests, the “gold standard” of aquifer tests. Since these tests require major efforts for planning and execution, the data from these tests are worthy of careful interpretation. Pumping tests are generally interpreted using methods based on highly idealized conceptual models of the subsurface. The theory of these methods and their application in simple settings are treated well in several excellent textbooks and monographs. However, more often than not, when a hydrogeologist is charged with interpreting the results of an actual test, he/she often discovers that the data do not look like those in a textbook. Data are typically noisy, do not approximate theoretical curves, and frequently yield inconsistent estimates of aquifer properties. This one-day course is designed to assist groundwater professionals in bridging the gap between theory and practice. The objective of the course is to hone the critical thinking skills of practitioners responsible for interpreting data from aquifer tests in complex natural settings.

Intended for students and professionals familiar with groundwater flow concepts who are interested in simulating the fate and transport of contaminants in groundwater, this course aims to teach attendees the underlying theoretical concepts and provide a modeling toolkit for simulating groundwater solute transport to address practical contamination and remediation problems. The course is structured as a one-day course and consists of theory, practical examples, and demonstration examples to address practical problems.

This half-day course introduces participants to Texture2Par for integrating texture and sediment data obtained from well logs and geophysical data obtained from surface and airborne investigations. The course provides insights into the features of Texture2Par, including power-law methods for parameterization including depth-dependence, co-kriging for multiple data sources, spatial interpolation methods, flexible variogram support. By combining mathematical theory, practical demonstrations, and real-world examples, attendees will learn how to efficiently generate realistic, spatially varying aquifer parameters for hydrologic models and calibration efforts and seamlessly integrate calibration within programs such as PEST.
