Description  Back to Top

RETC is a program for analyzing the hydraulic conductivity properties of unsaturated soils. The parametric models of Brooks-Corey and van Genuchten are used to represent the soil water retention curve, and the theoretical pore-size distribution models of Mualem and Burdine predict the unsaturated hydraulic conductivity function. The simulation can be generated from observed soil water retention data, assuming that one observed conductivity value (not necessarily at saturation) is available. The program also permits users to fit analytical functions simultaneously to observed water retention and hydraulic conductivity data.

To run RETC, you will need the following:

Installation and Start-Up  Back to Top

Getting Started:

You will need unzipping (compression) software to uncompress ZIP files. If you need to load compression software on your computer, free software is available for download on the internet at the following sites:

Leaving EPA -> http://www.pkunzip.com -  PKUNZIP home page
Leaving EPA -> http://www.info-zip.org/ - InfoZip Wiz

Installing the Program:

Two files are available for download:

  1. Go to Windows Explorer and create a directory (folder) named RETC.
  2. Download RETC.ZIP and RETC.PDF to the new RETC directory.
  3. Unzip RETC.ZIP to the RETC directory.
  4. Review the Users Manual (RETC.PDF) for instruction on running the model.
