Abstract
The following equation describes water retention in clayey materials: VM(W)s = 1.24 VM(W)S0-a Log (S/S0). The VM(W)S0 constant depends princ ipally on the pore space delimited by the clay matrix, and is calculat ed from the water content at a suction pressure of 100 kPa. The coeffi cient a is more directly related to the submacroscopic organization of the materials and their energetic history.
