At headwater channels in particular, the landslide of slopes with water body intersection, together with earth dam failures frequently become a main contribution to debris flow. The use of a computer model for slope stability evaluation of an arbitrary earthwork based on the Bishop's method is discussed. Similarly to that of Peterson, it adopts the assumption of a circular shape of the sliding body and evaluates the balance between the forces acting in the direction of the failure (destructing

The program applies both for earth dams and for natural land-sliding. The AutoCAD engine provides for visual generation of an almost unlimited number of shapes of the body 'segments', being interfaced with the input/output utilities of the soil mechanics module.
