Abstract

Since the early nineties SAR has been developed to provide contributions to several areas of the environmental risk monitoring. With the launch of X-Band Very High Resolution sensors, a significant advance in the extension of the applications to the monitoring of deformation affecting the built environment exposed to hazards has been achieved. In this work we summarize the outcomes of the studies resulting from the application of our interferometric chain developed for the processing of data acquired by the COSMO-SkyMed constellation. Applications regard geophysical processes of seismic and volcanic genesis, as well as areas affected by landslides and cultural heritage.

Abstract

The paper investigates the effects of indigenous vegetation on the shear strength of loose pyroclastic soils of the Campania region (Southern Italy); these soils are frequently affected by shallow landslides 1-2m deep that experience static liquefaction during the post-failure stage. Perennial graminae grasses were seeded in a 1D column 2 m high and filled by pyroclastic soils, allowing the root to grow under atmospheric conditions. A noninvasive sampling procedure was adopted to take the vegetated soil samples, in which the roots were in their natural geometrical distribution. For each rooted sample, the root biomass RM was measured, and the root volume density RVD was calculated. Isotropic consolidated triaxial tests in both drained and undrained conditions were performed on the rooted specimens, as well as on bare specimens as a control. The obtained results showed that the roots generally provided an increment to the soil strength. In drained conditions a reduction in the volumetric deformation was observed, which, under undrained conditions, was reflected in a general reduction of the excess pore water pressures with a possible inhibition of the static liquefaction occurrence. This study highlights the potential role of grass roots as bio-engineering practice for stabilizing shallow covers of pyroclastic soils.
