Holocene stratigraphic architecture and current land subsidence of the Volturno coastal plain (northern Campania, southern Italy)

Aim of the present study is the assessment of the ground deformation trends referred to almost two decades (years 1992-2008), which characterize the alluvial plain of the Volturno river, located in northern Campania coastal area (Italy). The spatial analysis of the SAR data and stratigraphic architecture highlighted the major ground deformation occurring within the outer boundary of the incised paleo-valley, corresponding to the Holocene alluvial/transitional filling. Soil properties like compressibility, permeability, coefficients of primary and secondary consolidation, can greatly help in understanding the deformation process under observation and in quantifying the contribution to the overall rate of settlement of primary consolidation and creep.
