Geotechnical studies on the shallowest soil deposits of the Venice lagoon, up to a few meters below ground level, are relatively unusual.
Geotechnical research is usually concerned with the characterisation of deeper soils and is directly related to building foundations and other civil engineering works [e.g. Simonini & Cola, 2000].
However, geotechnical research on the shallowest deposits of wetlands and marshes could be of great interest for the analysis and the modelling of some of the relevant processes occurring in the lagoon, such as the evolution of the stability of the marsh boundaries or the erosion of the channel banks and/or the upper crust of the marsh. To this purpose it is necessary to develop a suitable constitutive model for these soils that would be capable of predicting their drained/undrained response under different conditions.
A new preliminary geotechnical investigation was therefore undertaken as a first-step characterisation of the soils within some marshes in the north-eastern lagoon area. The results of this investigation should act as a guide to plan a second-step study, which would be mostly concerned with the mechanical behaviour of the soils.
The investigation commenced at the S. Felice marsh where a basic classification of soils, together with in-situ and laboratory tests, was performed.
In particular, with the specific aim of measuring the hydraulic response of the soils, permeability in both the vertical and the horizontal direction on a small and large scale was measured in the marsh soils. In addition, the pore pressure evolution in the marsh, as a consequence of the tidal range, was also measured. This paper presents and discusses the preliminary results of the investigation carried out so far at the S. Felice marsh.
