Modeling of Hysteretic Behavior of Soil–Water Retention Curves Using an Original Pore Network Model

Résumé

Soil-Water Retention Curve (SRWC), also called soil moisture characteristic, is used for simulation models of soil water storage or soil aggregate stability. The present study addresses the modeling of SRWC with particular attention paid to hysteresis effects of water filling and draining the pores attributed to ink-bottle effects. For that purpose, an idealized pore size distribution previously developed for predicting water sorption isotherms on cementitious materials, and which can consider the double porosity structure of soils, is used. An inverse analysis performed on experimental results of SRWC obtained on different types of soils has allowed to propose a calibration method of parameters involved in the definition of the idealized pore size distribution that can be assessed from mercury intrusion porosimetry tests (MIP) and from grain size distribution (GSD). The model adequately reproduces the hysteretic behavior of SRWC and can also predict the specific surface area.
