| Zusammenfassung |
| Underground water extraction, natural gas storage either in depleted hydrocarbon reservoirs
or in aquifers, and excavations for civil works (e.g. underground passageways, car parks, etc.)
in flat areas are responsible for surface deformation that can damage pre-existing structures
and modify drainage pathways.
Deformation patterns associated to different underground show in many cases typical
patterns. Their recognition can help in disentangling different processes when occurring in
areas already affected by natural subsidence, such as coastal areas and inner sedimentary
plains. Moreover, assessing the extent of human-induced deformation can help in identifying
causes, modelling phenomena, predicting their evolution and adopting proper remedial
measures.
Advanced Satellite Interferometry provides a synoptic view of surface displacements over
large areas and long time-spans and has become a standard in several Italian regions where
underground fluid injection and withdrawal is going on. The integration of interferometric
measurements with ground (leveling, GPS) and underground (borehole extensometers,
piezometers, micro-seismic) monitoring networks can provide an exhaustive framework of
the effect induced at surface level by underground human activities at local and regional
scale. Documented case studies demonstrating the effectiveness of the above approach will be
presented. |
