Darcy Flow:

Steady-State Water Movement in Soils

 

Authors:

D.L. Nofziger and Jinquan Wu

 

Purpose:

To solve the Darcy and Buckingham-Darcy equations for steady-state water movement in soils and to display the predictions of these models in graphical form. The software solves the equations for one or two layers of soil. Both saturated and unsaturated flow can be simulated.

Documentation:

A manual outlining the purpose, model, and simplifications used in this program is available here.

   

Computer Platform:

The software is written in Java and runs as a Web Start application. The Java  run-time package and Web Start software are  available free of charge from Sun Microsystems, Inc. The program was developed and tested on various Windows platforms as well as on Linux and MacOS X. We recommend 256 MB or more of Random Access Memory. Approximately 40 MB of disk space is required. 

 

Link for Java Software:

Before a Java Web Start program can be used on a computer, the supporting software must be installed. This is needed only 1 time per computer no matter how many different applications use it. Sun Microsystems Inc provides this package free of charge at http://java.sun.com/ or it can be downloaded here. If this is the first time you are using it, just download the file from the site above. Follow the instructions given there for installations. I recommend that you accept the default values proposed in the install process. 

 

Download/Execute Program:

Click here to download and start the program. If you use the program more than one time, you will be given the option of storing it on your local computer. You can then start the program without coming to this page with a web browser.
