Introduction 1 Introduction SLIDE is a 2D slope stability program for evaluating the safety factor of circular or non-circular failure surfaces in soil or rock slopes. SLIDE is very simple to use, and yet complex models can be created and analyzed quickly and2D seepage modeling is valuable in many engineering applications. Geotechnical engineers use seepage modeling to estimate groundwater flows through structures, or to evaluate stability of water retention structures. Environmental engineers use seepage modeling to analyze contaminant transport or infiltration through landfill covers, for example.
