Lacustrine deposits

Lakes are dynamic and complex systems, whose depositional processes and sedimentation are affected by climatic and tectonic events (Scott et al. 2012 and the references herein). In addition, the great physicochemical variability among lakes, in terms of origin, size, morphology, catchment size, and water biochemistry influence the nature and the rate of lacustrine deposits’ formation . The mechanical properties of such soils are quite variable, depending on the dominant soil fractions, the type of clay mineral content and the organic matter. Commonly, such soils show high compressibility and low mechanical resistance that can induce subsidence under static loading (that is a plastic progressive settlement) and liquefaction under dynamic loading when the groundwater is shallow.
