The Vietnamese Mekong Delta was formed by rapid transgression during the second half of Holocene deposition mainly unconsolidated, fine-grained (clayey) sediments undergoing high compaction rates. natural subsidence can seriously impact already vulnerable delta plain as its low elevation exposes to global sea level rise, flooding, salinization. Human activities such groundwater pumping, infrastructural loading, sand mining and dam construction have exacerbated effects consolidation. Here we...
Abstract Over the past decades coastal marshes around world have declined dramatically. Their deterioration is controlled by scarcity of sediments, erosion and accelerated rise relative sea-level. The feedbacks between these processes control marsh evolution determine their long-term survivability. Aggradation a to keep pace with sea-level mainly depends on interplay sedimentation autocompaction, but interactions are severely understudied. Here we present an in-situ loading experiment...
Abstract The resilience of marsh ecosystems to expected sea-level rise is determined by a complex interplay organic and inorganic sedimentation dynamics. Marshes have formed over past centuries millennia consist extremely reactive bodies with sediments that can experience high compaction. Here we provide quantification the degree which history salt affect its long-term evolution. A dataset elevation dynamics was established in Venice Lagoon (Italy) interpreted using physics-based model...
The availability of Earth Observation (EO) data, which are nowadays freely accessible to an increasing extent, has significantly advanced large-scale monitoring capabilities for geological hazards, particularly in terms acquisition frequency and areal coverage. This progress been especially evident land subsidence. By the first quarter 2022, Copernicus European Ground Motion Service (EGMS) began providing ground displacement data at level, offering valuable insights into surface movements...
Abstract Although the beginning of reservoir geomechanics dates back to late 1960s, only recently stochastical geomechanical modelling has been introduced into general framework operational planning. In this study, ensemble smoother (ES) algorithm, i.e., an ensemble‐based data assimilation method, is employed reduce uncertainty constitutive parameters characterizing model underground gas storage (UGS) field situated in upper Adriatic sedimentary basin (Italy), Lombardia UGS. The based on a...
This contribution presents the methodology and results of modeling studies conducted as part an international research collaboration that aims to develop innovative approach characterize from hydrogeological point view water-stressed Mediterranean basins experiencing land subsidence due excessive groundwater extraction. By integrating remote sensing-derived rates with iterative implementation numerical flow geomechanical modeling, we developed improve estimation parameters, mainly hydraulic...
ABSTRACT Assessing the safety and environmental impacts of subsurface resource exploitation management is critical requires robust geomechanical modeling. However, uncertainties stemming from model assumptions, intrinsic variability governing parameters, data errors challenge reliability predictions. In absence direct measurements, inverse modeling stochastic assimilation methods can offer reliable solutions, but in complex large‐scale settings, computational expense become prohibitive. To...
Abstract. Interpretation of land subsidence time-series to understand the evolution phenomenon and existing relationships between triggers measured displacements is a great challenge. Continuous wavelet transform (CWT) powerful signal processing method mainly suitable for analysis individual nonstationary time-series. CWT expands into time-frequency space allowing identification localized periodicities. Complementarily, Cross Wavelet Transform (XWT) Coherence (WTC) methods allow comparison...
Abstract. Understanding the causes and mechanisms of land subsidence is crucial, especially in densely populated coastal plains. In this work, we calculated rates (SR) Po plain, averaged over last 5.6 120 kyr, providing information about movements on intermediate (103–105 years) time scales. The calculation SR relied upon core-based correlation two lagoon horizons tens km. Subsidence kyr appears to be controlled mainly by location buried tectonic structures, which turn sedimentation highly...
Abstract Anthropogenic land subsidence can be evaluated and predicted by numerical models, which are often built over deterministic analyses. However, uncertainties approximations present, as in any other modeling activity of real-world phenomena. This study aims at combining data assimilation techniques with a physically-based model anthropogenic novel comprehensive workflow, to overcome the main limitations concerning way traditional analyses use available measurements. The proposed...
In recent years, the awareness about critical importance of correctly dealing with uncertainty in numerical models is spreading over an increasing number application fields, including geomechanics for energy resources. Sources are related instance to mathematical constitutive law that describes deep rock behavior, geomechanical parameters and geological nature investigated field. Data assimilation techniques take advantage availability in-situ measurements order account reduce uncertainties...
Recent studies highlight the fragility of Mediterranean basin against climate stresses and difficulties managing sustainable development groundwater resources. In this work, main issues related to management have been identified from stakeholder’s perspective in following four representative water-stressed areas: coastal aquifer Comacchio (Italy), Alto Guadalentín (Spain), alluvial Gediz River (Turkey), Azraq (Azraq Wetland Reserve, Jordan). This has achieved by designing a methodology...

Abstract Ecogeomorphic characteristics of tidal marshes are strongly related to their elevation with respect the mean sea level. Predicting long‐term evolution and resilience such ecosystems in times rapid natural anthropogenic climate changes is critical importance. The notion that marsh result feedbacks between vegetation dynamics, sediment fluxes, consolidation, sea‐level widely recognized. However, interaction these processes has been poorly investigated until now. This contribution aims...

Coastal transitional environments (CTE) are among the most productive ecosystems in world, supporting various natural functions and providing important ecosystem services to human societies. Because of their low elevation, CTE expected be severely threatened by accelerated sea-level rise (SLR) resilience will depend on capability keep pace with SLR.
