Numerical profile modeling for transient groundwater flow at pit slope

Geomechanical and Hydrogeological tasks often require knowledge of groundwater level at different time-points. In usual hydrogeological practice, groundwater flow modeling is based on steady-state flow. As such, modeling results can provide analysis of groundwater final state only. More detailed results can be obtained if hydrogeological modeling is made for non-steady state (i.e., transient) groundwater flow. This paper describes approach of applying numerical profile modeling for transient flow to determine groundwater level, height of seepage and hydrodynamic flow parameters at various time-points for pit slope stability analysis using Slide2 software tools (Rocscience Inc.).
