| We use Landrain. List price is around $2,000. The program has a fairly steep learning curve, so at first it is not easy. You will need a topo with data points in a easting, northing, elevation format to input into the program.
Here is a link to their site

I also use a program I got when I attended the Overholt drainage school at Ohio State. You might contact the people there to get more information. The 2010 program is coming up . It is excellent. Here is a link that tells about the school.

This would give you some of the tools a tile contractor would use. | |
