    Unsaturated Soils: Research and Applications contains 247 papers presented at 6th International Conference on Unsaturated Soils (UNSAT2014, Sydney, Australia, 2-4 July 2014). The two volumes provide an overview of recent experimental and theoretical advances in a wide variety of topics related to unsaturated soil mechanics:

    - Unsaturated Soil Behavior
    - Experimentation
    - Modelling
    - Case Histories
    - Geotechnical Engineering Problems
