The Fourth Pan-American Conference on Unsaturated Soils (PanAm UNSAT 2025) will be held June 22-25, 2025 in Ottawa, ON, Canada. The website is: www.panam-unsat2025.ca

The conference’s main theme is Unsaturated Soils for All Environments, and will include typical topics in unsaturated soils, but also aspires to include special topics on the role of unsaturated mechanics in cold regions geotechnique, the role of unsaturated soils in managing the impacts of climate change, as well as practical application of unsaturated soil theory in geohazards, mining, and other fields.

We are very pleased to have already secured speakers of note from academia and from consulting, including Del Fredlund, Daichao Sheng, and Mike O’Kane, who will speak on engineering decisions employing unsaturated soil mechanics, unsaturated soils in cold regions, and reflections on 30 years of application of unsaturated soil mechanics in the mining industry, respectively. Look for additional information on our speaker list as it is updated on our website, which will include presenters throughout the PanAm region and representing multiple topics in unsaturated soils.

Final papers will be published with Springer conference series collection (accessible through many libraries and indexed in Web of Science and other citation databases) and the proceedings will be available pre-conference. We are also excited to announce that after the conference, select papers will be invited for submission to a Special Issue of the Journal Geotechnical and Geological Engineering.

The Call for Abstracts is now OPEN. Details can be found on the Call for Abstracts page of the conference website. Authors are invited to identify one or more of the following topics with their submission. The deadline to submit abstracts to PanAm UNSAT 2025 is March 27, 2024.
