Advanced FEFLOW using PEST

For the first time in Brazil the author of the PEST tool John Doherty will be together with the PhD Nilson Guiguer will be together for a FEFLOW course advancing with the use of PEST

This course will be aimed at those professionals who already have experience in modeling and want to learn about how to solve challenges that appear in more complex applications.

The first 3 days will cover which best parameters to use for simulations of non-confined aquifers and considering unsaturated zones, how to introduce faults and karst zones in models, how to optimize solvers, density-dependent flow and generation of unstructured meshes with geological models.

In the last 2 days, advanced topics on the use of PEST for automatic model calibration will be covered. Use of Pilot points, analysis of uncertainty in predictions, use of scripts for simultaneous simulation of various scenarios

In addition to the presence of John Doherty, author of PEST and will also have the presence of a DHI / WASY instructor from the FEFLOW development and application team for complex problems.



He is a specialist in numerical groundwater models. Author of many computer models, including Visual MODFLOW, Flowpath, Flonet and others. Master in Hydrology and Hydraulics from the University of São Paulo and PhD in Hydrogeology from the University of Waterloo, Canada. He served as a consultant on numerous projects, applying mining models, water resource management, environmental impacts and remediation. He is a recognized instructor, having taught more than 100 professional courses in various parts of the world. He is currently a managing partner at Water Services and Technologies and professor of undergraduate and graduate courses at the Federal University of Santa Catarina.


John Doherty is the author of PEST, the most recognized free software package on the market for groundwater calibration and uncertainty analysis. Dr. Doherty has been working in the water sector for more than 35 years, first as an exploration geophysicist and then as a modeler. He worked for the government and industry and held positions at several universities, as a researcher and as an advisor to several graduate students. He is currently president of the Australian Watermark Numerical Computing, which specializes in consulting, research, programming and education on issues related to the implementation of models for environmental management and impact assessment.
