**Figure A1.** Project area of LIFE Lagoon ReFresh in the northern Venice Lagoon. Current state of salinity condition (small panel, bottom) and expected state after the creation of a freshwater input from the Sile river (low tide conditions). The freshwater inflow and morphological interventions are also represented. The diffusion of freshwater during low tide condition was obtained from numerical simulation [61].
