The Hellenic Society for Soil Mechanics and Geotechnical Engineering (HSSMGE) is delighted to welcome you all to the 8th International Conference on Unsaturated Soils “Towards Unsaturated Soils Engineering” to be held on Milos Island, Greece, between May 3rd to 5th, 2023. The UNSAT2023, organized under the auspices of the ISSMGE Technical Committee TC106, follows the successful past UNSAT conferences held in Hong Kong (2018), Sydney (2014), Barcelona (2010), Phoenix (2006), Recife (2002), Beijing (1998) and Paris (1995).

As past UNSAT conferences, UNSAT2023 aims at providing researchers and practitioners alike with a unique opportunity of sharing up-to-date knowledge on Unsaturated Soil Mechanics and Engineering. The 3rd Blight Lecture, several keynote lectures by renowned experts in the field, numerous papers and a parallel technical exhibition in a relaxed environment will make for a most fruitful scientific event and a unique opportunity for the unsaturated soils community to meet again in person after several years of Covid restrictions. Recent experience in Greece has shown that in-person events are now possible provided nothing new emerges with the world pandemic.
