Book Description

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
- Multidisciplinary and New Areas

Unsaturated Soils: Research and Applications presents a wealth of information, and is of interest to researchers and practising engineers in soil mechanics and geotechnical engineering.

These proceedings are dedicated to Professor Geoffrey E. Blight (1934-2013), who passed in November 2013.
