In order to determine soil-water retention (SWR) behavior of not-plastic particulate medium, the invading pressure in inter-particle level is correlated to the governing effective pore area in wetting and drying paths. In a drying path, the air-entry pressure (AEP) of a pore throat, where the area of a cavity is minimum, with numerically solving the Young-Laplace curvature equation using the finite difference method and Newton-Raphson (Jacobian) approximation technique is determined. Similarly, the water-entry pressure (WEP) is correlated to a maximum area of cavity.
