... intuitively understand the WRC as a cumulative pore size distribution. However, a strictly physical formulation of the WRC is very difficult. Thus, in soil physics, empirical models are the common choice. A frequently used model for the WRC is the model of Brooks and Corey (1964) (hereafter referred...
