Probabilistic Calibration of a Dynamic Model for Predicting Rainfall-Controlled Landslides

Reliability analysis of riverbank stability accounting for the intrinsic variability of unsaturated soil parameters

“…Figure 5 shows the SWRCs obtained by fitting the available laboratory data using eq. (11). The plot provides the effective degree of saturation Se as a function of suction s. Although all the samples were taken from the same soil unit, a significant degree of heterogeneity is observed on the hydraulic behaviour of the soil in partially saturated conditions.…”

“…A large number of research contributions (e.g. [9][10][11][12][13][14]), based on either theoretical applications or failure case studies, have discussed the effect of uncertainties and spatial variation of soil shear strength on slope analysis reliability, whilst only few available studies have also considered the variability of hydraulic properties, particularly those governing the behaviour of unsaturated soils [15][16]. An even more limited number of published works [17] have actually tackled the problem with reference to existing river embankments and a substantial lack of applications to relevant case studies is thus observed.…”
