  • Monitoring of a full-scale embankment experiment regarding soil–vegetation–atmosphere interactions 

    Oorthuis Gómez, Raül; Hurlimann Ziegler, Marcel; Fraccica, Alessandro; Lloret Morancho, Antonio; Moya Sánchez, José; Puig i Polo, Càrol; Vaunat, Jean (2018-06)
    Article
    Accés obert
    Slope mass-wasting like shallow slides are mostly triggered by climate effects, such as rainfall, and soil–vegetation–atmosphere (SVA) interactions play a key role. SVA interactions are studied by a full-scale embankment ...
