Hi Purvis
Just wanted to let you know that I agree with Focht3, software does not help you out of a problem, but sometimes makes more of a problem. I know because I have learnt this the hard way through PPC applications for landfills! There is often more to the problem as well - my advice (as Focht3) is to sit down with a geotechnical guy and discuss what may/is involved. You must be clear in your head that you understand the geology of the site, boreholes!! working plans of site, waste type, groundwater levels, soil strengths, etc. If you have a clear understanding in the beginning, then you will NOT need to do "hundreds" of evaluations. Slope/w is a good software package.
It is always good to learn something new (add to the skills list), good luck! If you have any questions then don't hesistate to ask me. I've been there too!
