Short summary
An in-situ loading test was carried out in the Lazzaretto Nuovo salt-marsh in the Venice Lagoon, Italy. The test was aimed at characterizing the geotechnical properties of soils forming the marsh sedimentary body deposits. In fact porosity and compressibility are of paramount importance to quantify consolidation versus accretion and relative sea level rise. The fate of coastal marshlands in the next future will strongly depend of these processes.
