Sensitivity analysis applied to the flooding process is discussed in the paper. The analysis was done as part of the ISMOP project devoted to elaborating and designing a complex system for embankment monitoring and threat forecasting. The analysis was performed using selected geotechnical parameters that describe embankment state. It was shown that the sensitivity analysis method is very practical for detecting places where the largest vertical displacement and pore pressure distribution are observed. The sensitivity analysis was carried out for a single flood wave numerical experiment as well as for a double successive flood wave experiment. Comparison of the results allowed us to detect the places where the biggest differences in total relative sensitivity values are observed. Plots of these differences can help to indicate the particular places within the embankment that are the most influenced by successive flood waves and should be especially examined during field experiments as part of the ISMOP project.
