Analysis of rainfall-induced shallow landslides – a case study in owczary near gorlice

Keywords: slope stability, rainfall, infiltration, shallow landslides, the Carpathians
Abstract: Results of geotechnical research of two shallow landslides in Owczary near Gorlice induced by torrential rainfall in 3–4 June 2010 are presented in the paper. The main purpose of the paper was analysis of rainfall infiltration process and its influence on slope stability conditions. Analysis of transient seepage were done using one-dimensional infiltration Iverson and Green-Ampt models, and two-dimensional model using physical Richards’ equation. The calculation results performed for analyzed slopes revealed that during considered rainfall were preferable conditions for infiltration process. The rainwater could have seeped up to impermeable layer and formed perched groundwater table inducing seepage forces. Comparative analysis of tested infiltration models showed also that the numerical model based on Richards equation and Green-Ampt model give comparable results of calculations but results of matric suction changes calculated using Iverson model were much smaller than results obtained using numerical method.
