The paper presents the results of the sensitivity analysis of the variability of thermal conductivity and specific heat values on temperature field and pore pressure distribution during the flooding process simulation. The sensitivity analysis was carried out using data obtained from numerical modellings. During numerical modellings the simulation of flooding process included flooding and discharging the tank, with maximum water level equal to 3.0 m was performed. 2D model was realized using Fast Lagrangian Analysis of Continua (FLAC) 7.0 software, which is a two-dimensional explicit finite difference program for engineering mechanics computation. The results presented in this paper show that the sensitivity analysis method is powerful technique that can be used in detection of area within the embankment where the biggest impact on variability of thermal conductivity are presented. It may be helpful in selecting the best area for pore pressure and temperature sensors location.
