Download a comprehensive tutorial that shows you how to use PEST to undertake state-of-the-art model parameter and predictive uncertainty analysis. Two complete worked examples are provided, one involving a surface water model (HSPF) and the other involving a groundwater model (MODFLOW). Also provided is the background theory (explained in an easy-to-read manner) and suggestions on how modern methods of data processing and uncertainty analysis such as are provided by PEST can be used as critical components of the environmental decision-making process.
If you have trouble downloading this file, let us know and we will send a copy to you.
Many thanks to the South Florida Water Management District for making development of this tutorial possible.
PEST documentation has just been completely re-written.
PEST now has a two-part manual. The first part describes PEST itself, including all of its regularisation and predictive analysis functionality. This part of the manual also describes the PEST-compatible CMAES_P and SCEUA_P global optimisers. The second part of the new PEST manual describes over one hundred programs that support the use of PEST in various ways - including PEST setup, statistical analysis and parameter/predictive error/uncertainty analysis.
The new PEST manual part I - complete documentation of PEST and PEST-compatible global optimisers
The new PEST manual part II - documentation of PEST utility support software (including utilities for parameter and predictive error/uncertainty analysis
Documentation for Unix version of PEST (includes compilation instructions)
Documentation for BEOPEST for Windows
Documentation for PEST-Model Interface and Parallelization Modules
Manual for the Groundwater Data Utilities - Part A
Manual for the Groundwater Data Utilities - Part B
Manual for the Groundwater Data Utilities - Part C
Manual for MODFLOW-ASP
Manual for Surface Water Utilities
Improvements to version 16 of PEST include the following.
The issue of improved
inter-operability with the PEST++ suite is important. PEST++ is more than just an inversion program to use in place of PEST.
PEST++ is a suite of programs that perform tasks such as global sensitivity analysis and
optimization under uncertainty. It also includes an iterative ensemble smoother which can
efficiently calculate samples of the posterior probability distribution of
parameters used by complex, highly parameterized models. All members of the
PEST++ suite use an advanced, modular, nonintrusive, parallel run manager named PANTHER.
This will soon be publicly available, so that anyone who writes code in C, C++,
FORTRAN or Python can have easy access to this same model run management functionality.
Many thanks to the Queensland
Water Modelling Network for helping with improvements to PANTHER, and for help in
writing software and manuals that improve inter-operability between the PEST
and PEST++ suites.
Download the latest PC version of PEST.
Unzip the contents to a directory cited in the PATH environment variable. (This is very important as, when undertaking SVD-assisted parameter estimation, PEST runs the parcalc.exe and picalc.exe utility programs. It is essential that the operating system knows where to find these).
Make sure that directories holding older versions of PEST are no longer in the PATH string, as old versions of parcalc.exe and picalc.exe are not compatible with the new PEST.
Download 64bit versions of certain programs of the PEST suite compiled using the Intel(R) 64 bit compiler.
Download BEOPEST for Windows.
Download the latest Unix version of PEST.
Unzip the contents to find a tar file with PEST source code, makefile and examples. Copy the tar file to a suitable directory on your machine, for example a directory named /pest. Then extract its contents using the "-xvf" switch. Follow the instructions provided in the documentation for Unix PEST (see the link in the "Documentation" section above).
Download the parameter list processor PLPROC including full documentation.
Download the Groundwater Data Utilities suite for the PC. Unzip this file to obtain PC-executable versions of the Groundwater Data Utilities.
Source code for the Groundwater Data Utilities can be obtained on request. Compilation of these utilities requires that a library be built first, and then the executables themselves. However for many of these utilities, the source code has been collected into discrete files for ease of cross-platform compilation. Write to us if you need more information.
Download MF2K-ASP and a MODFLOW2000-to-PEST translator. Unzip to obtain PC executables and documentation. Write to us if you would like the source code.
Download the Surface Water Utilities for the PC. Unzip this file to obtain PC-executable versions of PEST's surface water utilities.
Download HSPF optimized for use with PEST. Unzip this file to obtain a PC-executable version of HSPF version 12. A more up-to-date version can be downloaded from AquaTerra Consultants.
Download FORTRAN 90 PEST-Model Interface and Parallelization Modules. Unzip to a directory of your choice.
