Polder Effects on Sediment-to-Soil Conversion: Water Table, Residual Available Water Capacity, and Salt Stress Interdependence
Figure 20
Schematic representation of the mesopore and fracture opening of the clay matrix for the different water contents associated with the increasing depths. (a) Ductile-to-brittle behavior of the clay material taking into account the - couple evolution and the successive steps of fracturing: (1) ductile behavior in the plastic-to-liquid state domain, (2) plasticity limit (), (3) brittle comportment in the solid state [14]. = gravimetric water content; = void ratio; = shear stress; = equivalent pore diameter. (b) SEM microphotography of a mesopore adjacent to the clay matrix.
