“…Young sedimentary sequences, caused by the succession of various cycles of stability and meander migration over the past centuries, alternate with stratigraphic stretches of fine, more consolidated materials (silts and clays) deposited during historic phases of floodplain aggradation (Conesa-García 2012). Very variable subsidence values have also been obtained using InSAR in various Mediterranean floodplains, such as the Emilia-Romagna area, in the Po Plain (-2 to -39 mm yr -1 ) during recent decades (Amorosi et al 2004), the flat plain of southern Lombardia (displacements from -10 to -30 mm for the period 1992-2000) (Meisina et al 2006), the Lucca floodplain (central Italy) (about 20-30 mm during 1992-2003) ( Disperati et al 2006) and the Campanian Plain, southern Italy (up to -5 mm yr -1 from 1995 to 2011) (Cascini et al 2013;Peduto et al 2015). Nevertheless, in contrast to the VMSR, in these plains there is a lower presence of fine-grained materials, particularly in Emilia Romana, where the main channel-related lithofacies are massive, horizontally or crossstratified gravels, the chutes or abandoned channels consist of lens-shaped sand bodies topping gravel units, and in flood areas coarse-grained sediments are often abruptly overlain by tabular silty-clay deposits.…”

“…The use of DInSAR for the study of subsidence due to aquifer abstraction was applied first by Galloway et al (1998), and subsequently to other aquifer systems worldwide. These works document (1) the spatial and temporal evolution of aquifer deformation (Tomás et al 2005;Galloway and Hoffmann 2007;Stramondo et al 2008;Vilardo et al 2009;Heleno et al 2011;Herrera et al 2009a;Cigna et al 2012;Raspini et al 2012;Peduto et al 2015); (2) numerical models capable of reproducing aquifer related subsidence (Hoffmann et al 2003;Herrera et al 2009b;Tomás et al 2010;Calderhead et al 2011;Raspini et al 2014); (3) urban areas and structures affected by ground subsidence (Karila et al 2005;Cascini et al 2007Cascini et al , 2013Bru et al 2013;Herrera et al 2010;Tapete et al 2012;Tomás et al 2012;Sousa and Bastos 2013;Sanabria et al 2014). Within this regional context of subsidence induced by groundwater abstraction, there are no previous works targeting different deformational behaviours in alluvial forms with different lithofacies and sediment ages.…”

Abstract:It is widely known that differential land subsidence in a valley significantly controls its fluvial dynamics. Nevertheless, major uncertainty exists about the way in which alluvial forms respond to this process. In this study, morphological and lithostratigraphic data have been combined with Advanced Differential Interferometry (A-DInSAR) to detect changes in alluvial landform elevations and to verify the existence of a differential subsidence pattern influenced by active sedimentary dynamics. For this purpose, the middle reach of the Segura River valley (Vega Media of the Segura River, VMSR), in south-east Spain, was chosen as the study area. The VMSR is an alluvial area affected by subsidence processes in close conjunction with depositional conditions, ground-water withdrawals and faults. A high scale mapping of the main younger sedimentary units was carried out by combining multi-temporal aerial photographs, high resolution DEMs derived from LIDAR data, GNSS data and field work. In addition, lithostratigraphic descriptions were obtained from geotechnical drilling and trenching. Finally, ground surface displacements, measured using A-DInSAR for the periods 1995-2005 and 2004-2008,

“…A-DInSAR techniques provide the displacement estimates, the velocity map and the displacements time series for the whole observation period along the satellite Line of Sight (LOS). These techniques have been effectively used to the subsidence monitoring as shown in many published works (Bru et al, 2013;Cascini et al, 2013;Ezquerro et al, 2014;Modoni et al, 2013;Sanabria et al, 2014;Tomás et al, 2014). Specifically, in the present work, the DInSAR processing of C-band SAR images achieved through the Stable Point Network (SPN) technique (Arnaud et al, 2003) for the period 1995-2008(Terrafirma, 2008 has been used.…”

Regional subsidence modelling in Murcia city (SE Spain) using 1-D vertical finite element analysis and 2-D interpolation of ground surface displacements

Abstract.Subsidence is a hazard that may have natural or anthropogenic origin causing important economic losses. The area of Murcia city (SE Spain) has been affected by subsidence due to groundwater overexploitation since the year 1992. The main observed historical piezometric level declines occurred in the periods 1982-1984, 1992-1995 and 2004-2008 and showed a close correlation with the temporal evolution of ground displacements. Since 2008, the pressure recovery in the aquifer has led to an uplift of the ground surface that has been detected by the extensometers. In the present work an elastic hydro-mechanical finite element code has been used to compute the subsidence time series for 24 geotechnical boreholes, prescribing the measured groundwater table evolution. The achieved results have been compared with the displacements estimated through an advanced DIn-SAR technique and measured by the extensometers. These spatio-temporal comparisons have showed that, in spite of the limited geomechanical data available, the model has turned out to satisfactorily reproduce the subsidence phenomenon affecting Murcia City. The model will allow the prediction of future induced deformations and the consequences of any piezometric level variation in the study area.

In this paper, we provide chronological constraints to reconstruct the Late Middle Pleistocene to Holocene geomorphological, stratigraphical and tectonic evolution of the inner Sarno plain, along the Tyrrhenian flank of Southern Italy. These constraints derive from tephrostratigraphical analysis and 40Ar/39Ar dating of volcanic deposits, chronologically constrained between ca. 40 ka and 184 ka, recovered from a borehole located in the pediment of the Sarno Mts. The lack of marine to transitional deposits in the borehole testifies that the entire area has been above sea level during this period. Conversely, analysis of previously drilled borehole data indicates the presence of an at least 200 m thick sequence of marine and transitional deposits beneath the Sarno Plain. The top of the marine to transitional deposits in the Sarno basin has been correlated with those in the San Valentino Torio High to the SW, dated to the MIS 5. Consequently, it may be envisaged that the upper portion of the marine deposits in the Sarno Plain also correlates with the MIS 5. This allows to estimate a mean subsidence rate in the last 125 ka, which is 0.32 mm/a. On the other hand, the uninterrupted 200 m‐thick marine succession means that subsidence in the Sarno basin was ≥0.7 mm/a during the preceding interval between ~285 ka and the last interglacial (LIG; MIS 9‐MIS 5). The subsidence was likely driven by the activity of the Sarno Fault, whose slip rate in the last 40 ka was significantly lower than the subsidence rate since the LIG and the MIS 9‐LIG interval. This implies that the fault slip rate has decreased during the last 285 ka. This paper provides a valuable contribution to the study of the complex interplay between glacio‐eustatic oscillations and tectonics to assess reliable paleo‐sea level indicators.
