GNGTS 2018 S essione 1.2 211 Fig 2 - Top: Piave at Belluno basin; Center: Piave at Segusino basin; Bottom: Cordevole at Ponte Mas basin. Left: The green lines represent the hydrological basins defined in Val Belluna-Montello-Cansiglio area, the red dots the GPS stations position and in blue the rivers. Right: Comparison between temporal evolution of IC2 (blue) and water storage variations (red) in each hydrological basin. the Bassano-Valdobbiadene thrust fault (Fig. 3). Here, the water accumulates because of the larger permeability of the fractured rock faults, varying its level up to tens of meter and then generating pressure changes that cause the displacements reconstructed by IC2 (Fig. 1). The identification and characterization, both in space and time, of transient deformation signals is crucial in interpreting active tectonic processes. This is twofold; first because thanks to a proper modeling of non-seasonal transient deformation we can improve the accuracy of
