    Article
    Open Access
    Aquifer remediation with in-situ soil washing techniques and enhanced oil removal typically involves the injection of liquid solutions into the geological formation to displace and mobilize non-aqueous phase liquids (NAPLs). ...

    Alonso, Matías; Vu, Minh-Ngoc; Vaunat, Jean; Armand, Gilles; Gens Solé, Antonio; Plúa, Carlos; de Lesquen, Christophe; Ozanam, Odile (Institute of Physics (IOP), 2021-09)
    Article
    Open Access
    The French National Radioactive Waste Management Agency (Andra) is in charge of studying the disposal of high-level and intermediate-level long-lived waste (HLW and ILW-LL) in a deep geological repository (Cigéo project) ...
  • Performance of large diameter storage and sealing structures in a deep exothermic waste repository 

    Alonso, Matías; Vaunat, Jean; Olivella Pastallé, Sebastià; Gens Solé, Antonio; Vu, Minh-Ngoc (2022)
    Conference report
    Restricted access - publisher's policy
    The paper presents the work carried out to assess and simulate numerically the phenomenology behind the response of large diameter intermediate-level long-lived nuclear waste (ILW-LL) storage galleries and the corresponding ...
  • PFEM analysis of installation effects on axial performance of jacked piles in chalk 

    Ciantia, Matteo Oryem; Lei, Jiangtao; Monforte Vila, Lluís; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (International Centre for Numerical Methods in Engineering (CIMNE), 2021)
    Conference report
    Open Access
    Chalk is present in a large area of the East and South coast of the UK where renewables are now being installed. In most cases they are founded on displacement piles, whose design uses empirical methods or partial ...
  • Grain roughness effect on the critical state line of crushable sands 

    Lei, Jiangtao; Arroyo Alvarez de Toledo, Marcos; Ciantia, Matteo Oryem; Zhang, Ningning (University of Dundee, 2021)
    Conference report
    Open Access
    A recently proposed DEM model for materials with rough crushable grains (Zhang et al. 2021; Ciantia et al. 2015; Otsubo et al. 2017) is here employed to examine the effect of contact roughness on the critical state line, ...
  • FSLAM: A QGIS plugin for fast regional susceptibility assessment of rainfall-induced landslides 

    Guo, Zizheng; Torra i Truncal, Ona; Hurlimann Ziegler, Marcel; Abanco Martínez de Arenzana, Claudia; Medina Iglesias, Vicente César de (Elsevier, 2022-04)
    Article
    Restricted access - publisher's policy
    Shallow slope failures triggered by rainfall commonly pose considerable risks in mountainous areas. In order to delineate areas where landslides are more prone to occur within a region, we have designed and developed a ...
  • Rockfalls: analysis of the block fragmentation through field experiments 

    Gili Ripoll, José Antonio; Ruiz Carulla, Roger; Matas Casado, Gerard; Moya Sánchez, José; Prades Valls, Albert; Corominas Dulcet, Jordi; Lantada, Nieves; Núñez Andrés, María Amparo; Buill Pozuelo, Felipe; Puig i Polo, Càrol; Martínez Bofill, Joan; Salo Salgado, Lluis; Mavrouli, Olga Christina (2022-05)
    Article
    Open Access
    Fragmentation is a common feature of rockfall that exerts a strong control on the trajectories of the generated blocks, the impact energies, and the runout. In this paper, we present a set of four real-scale rockfall tests ...
  • Capturing rockfall kinematic and fragmentation parameters using high-speed camera system 

    Prades Valls, Albert; Corominas Dulcet, Jordi; Lantada, Nieves; Matas Casado, Gerard; Núñez Andrés, María Amparo (2022-06-05)
    Article
    Open Access
    This paper presents a procedure for tracking rockfall trajectories and extracting kinematic parameters from both the impacts and the resultant fragments. A set of full scale rockfall experiments was performed in a quarry ...
  • Interferometric SAR deformation timeseries: a quality index 

    Abera Wassie, Yismaw; Mirmazloumi, Seyedmohammad; Monserrat Hernández, Oriol; Crippa, Bruno; Palamá, Riccardo; Barra, Anna; Crosetto, Michele (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2021)
    Conference report
    Open Access
    Estimating unknown absolute phase from a wrapped observation is a challenging and ill-posed problem that possibly leads to misinterpretation of interferometric SAR (InSAR) deformation results. In this study, we introduce ...
  • Unconfined compressive strength of sand-fines mixtures treated with chemical grouts 

    Spagnoli, Giovanni; Seidl, W.; Romero Morales, Enrique Edgar; Arroyo Alvarez de Toledo, Marcos; Gómez Bonilla, Rodrigo Andrés; López López, José (CRC Press, 2021)
    Part of book or chapter of book
