abstract:
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.
