Hello
I am doing deformation analysis of unsaturated soil using complicated finite element program. Unfortunately the program is incapable of showing soil water retention curve (WRC) dependence on void ratio or bulk density ; i.e the software considers that WRC is inherent parameter of the soil being deformed. Any one can guide on how unrealistic such assumption is. Also, any guidance to references that considers this assumption is acceptable (as far as the coupled behavior of groundwater motion and deformation is concerned) would be hugely appreciated
