    The characterization of saline water intrusion (SWI) and its hydrodynamics is a key issue to understand submarine groundwater discharge (SGD) and manage groundwater resources in coastal areas. To test and compare different ...
  • Simulation of full-scale rockfall tests with a fragmentation model 

    Matas Casado, Gerard; Lantada, Nieves; Corominas Dulcet, Jordi; Gili Ripoll, José Antonio; Ruiz Carulla, Roger; Prades Valls, Albert (2020-05)
    Article
    Open Access
    In this paper, we present the upgraded version of RockGIS, a stochastic program for the numerical simulation of rockfalls and their fragmentation, based on a fractal model. The code has been improved to account for a range ...
  • A persistent scatterer interferometry procedure based on stable areas to filter the atmospheric component 

    Crosetto, Michele; Devanthéry Arasa, Nuria Virginia; Montserrat, Oriol; Barra, Anna; Cuevas Gonzalez, Maria; Mróz, Marek; Botey Bassols, Joan; Vázquez Suñé, Enric; Crippa, B. (Multidisciplinary Digital Publishing Institute (MDPI), 2018-11)
    Article
    Open Access
    This paper describes a Persistent Scatterer Interferometry (PSI) procedure to monitor the land deformation in an urban area induced by aquifer dewatering and the consequent drawdown of the water table. The procedure, based ...

    Flow within vegetation is one of the main driving forces for material exchange and energy transfer in wetland systems. Impacted by vegetation, the flow velocity profile illustrates distortions to the classic logarithmic ...
  • How does water-reliant industry affect groundwater systems in coastal Kenya? 

    Ferrer Ramos, Nuria; Folch Sancho, Albert; Lane, Mike; Olago, Dan; Katuva, Jacob; Thomson, Patrick; Jou Claus, Sonia; Hope, Rob; Custodio Gimena, Emilio (Elsevier, 2019-12)
    Article
