HYRCAN (/hərˈkeɪn/) (by-product of quarantine lockdown) is a free 2D slope stability program for evaluating the safety factor of circular failure surfaces in soil or rock slopes. HYRCAN is simple to use, and yet complex models can be created and analyzed quickly and easily. External loading, groundwater and support can all be modeled in a variety of ways. HYRCAN is free and available via http://geowizard.org. Web Page: http://geowizard.org http://roozbehgm.com Developer: Roozbeh Geraili Mikola, PhD, PE
