PEST Course 2017

Workshop Model Calibration and Uncertainty Analysis Using PEST

Summary

PEST (Parameter ESTimation) is a general-purpose, model-independent, parameter estimation and model predictive uncertainty analysis package. It is the most advanced software available for calibration and predictive uncertainty analysis of groundwater, subsurface reservoir, surface water, land use and other models.

The course will provide attendees with the foundations of parameter estimation theory, an understanding of the sources of uncertainty in predictions made by numerical models, and experience in using PEST to calibrate groundwater flow and transport model, and surface water models, and to explore the uncertainties of predictions made by these models.
The program for each day is a combination of lectures and practical sessions. The content of both the theoretical and practical sessions can (to at least to some extent) be defined by attendees according to their interests.

Target audience

Practitioners from a wide range of backgrounds will benefit from this course, whether new to PEST or with previous PEST experience.

To get the most out of the course, attendees should have modelling experience, preferably in the groundwater or surface water disciplines. However the material presented during the course will also benefit those who rely on models for decision-making purposes who need to have a better understanding of what models can and cannot achieve, but who do not necessarily build them.

Hands-on labs are GUI-independent and cover a variety of modelling disciplines, so that anyone interested in model calibration, parameter estimation, or the analysis of numerical model uncertainty can benefit from the course. Experience in working at the command line level is an advantage in doing the workshops. Make sure to bring your laptop so that we can install the software and workshops on it.
