Polder Effects on Sediment-to-Soil Conversion: Water Table, Residual Available Water Capacity, and Salt Stress Interdependence

Figure 19

Schematic representation of the relations prevailing between the microstructure behavior of the clay matrix and the macroscopic behavior at the field scale during the surface desiccation phenomenon (3 to 2 to 1) and during the consolidation in depth (3 to 4). 𝐾 = hydraulic conductivity measured by oedometer compressibility test on unfractured and saturated clay matrix 𝐾^∗ = surface hydraulic conductivity measured by Porcher test on the fractured soil (from Dudoignon et al. [13]).
