The role of the geological model in the analysis of land subsidence: a key lecture from the Volturno River alluvial plain (southern Italy)

The present study focused on the relationships between subsidence and geological geotechnical features of Volturno River alluvial coastal plain (northern Campania, Italy). Subsidence rates were determined through InSAR data analysis. A lithostratigraphic reconstruction was provided for Holocene succession that overlay a continuous, thick, volcaniclastic unit (Campania Grey Tuff) deposited 39 ka B.P. digital surface model carried out this showed palaeovalley morphology, allowing palaeodrainage network better modeling stratigraphic architecture post-CGT deposits. map overlain spatially with data. In whole plain, major ground deformations affect sedimentary piles filling engraved in volcanic compaction-free basement. Inside general trend, differential compaction detected within these deposits corresponding to occurrence clay peat different thicknesses, suggesting are due part primary consolidation large secondary consolidation.
