Multi-temporal Analysis of Areas under Landslide: Protecting Soil against Subsidence and Pollution

摘要

Landslide is a dangerous phenomenon according to geomechanical viewpoint, being able to produce huge damages because of sliding and can involve structures and infrastructures. However, mechanical aspects are generally recognized since they provoke the above consequences. Environmental aspects related to breaking in the land must be considered. Land breaks or cracks allow outside water, not only from rain, to reach surface and subterranean aquifers. Contacts between external waters, maybe containing diverse pollutants, and aquifers, would be considered as source of contamination. The paper illustrates an experimental multi-temporal monitoring of landslides that have been taking place at Colletorto town (Italy). The proposed method, by means of dedicated instrumentation, and subsequent modeling, has permitted to output innovating approach.
