Abstract
Pyroclastic soil covers in Campania region (South Italy), usually of 2-3 m depth, are systematically affected by rainfall induced shallow landslides in wet season, causing catastrophic consequences. This paper introduces an experimental study aimed to investigate the use of vegetation as a sustainable practice for stabilizing these soils. The first step of the study is focused on both (i) the growth of perennial graminae grass species with long roots in a 1D column and (ii) its effect along depth on induced soil suction during evapotranspiration in wet season. Results show that the effect of roots on increasing soil suction is observable in shallowest layers and it decreases with depth. Moreover, the presence of roots can change the initial soil suction conditions in soil during wet season, when rainfall induced flow-like landslides systematically occur.
