Hydrogeological models with (a) initial parameter Kf-values (above, provided by local company and engineers) and (b) with Kf-values calibrated through comparison of modelling results with piezometer levels measured in July 2012 and September 2013. c) Calculated dam stability scenario (most critical one among realistic scenarios) using average water level in the dam and reservoir and considering seismic effects: horizontal acceleration of 0.3 g and vertical acceleration of 0.15 g.
