Evaluating the Effects of High Tide on Venetian Stone Buildings: A Multi-Analytical Approach
Gloria Zaccariello, Elena Tesser, Rebecca Piovesan, Fabrizio Antonelli
Abstract:
Acqua alta (high water) is a natural phenomenon that generally occurs in the city of Venice (Italy) in autumn and springtime, when a combination of astronomical tide, strong south wind (scirocco) and seiche can cause a large water inflow into the Venetian lagoon. The consequences of these events are the overflowing of the canals and flooding of the pedestrian walkways, leading to the degradation of the stone buildings over time. With the aim to better understand the effects of high water and how to take action for preserving the cultural heritage of Venice, thirty samples of five varieties of carbonate lithotypes exposed to natural weathering were monitored in different areas of Venice and the island of Torcello. The present work shows the preliminary results obtained through a multi-analytical approach, evaluating the chemicalphysical alteration and the morphological variations through systematic monitoring every three months.
