4th International Symposium on Coupled Phenomena in Environmental Geotechnics

September 10-11, 2025, at Colorado State University, Fort Collins, Colorado, USA

About CPEG

Themes

The “International Symposium on Coupled Phenomena in Environmental Geotechnics (CPEG)” is a quadrennial event organized under the auspices of the Technical Committee TC215 (Environmental Geotechnics) of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE), with a focus on coupled processes (e.g., chemical-physical, bio-physical, multiphase flow, etc.) in environmental geotechnics.

The first symposium of the series was held in Torino (Italy) in 2013, the second in Leeds (UK) in 2017, the third virtually in 2021 hosted from Kyoto (Japan).

The fourth symposium, CPEG2025 will be held at Colorado State University in Fort Collins, Colorado, USA on September 10th and 11th, 2025. The symposium will provide an opportunity for networking and discussion around coupled phenomena in environmental geotechnics – where we are at, and where we are going. We welcome submissions from all over the world.

Call for Abstracts

Coupled Processes, e.g., improved understanding of thermo-hydro-mechanical-chemical-bio-gas processes within soils, rock, and solid waste.

Waste Geotechnics, e.g., tailings and mine waste, radioactive waste disposal, waste degradation and settlement.

Carbon Capture and Storage Sequestration, e.g., carbon capture and storage (CCS), monitoring and verification of CCS

Surface Containment, e.g., engineered barriers/liners, covers, in situ barriers, bioreactor landfilling

Sub-Aqueous Containment, e.g., sub-aqueous capping of contaminated sediments, coupled settlement and contaminant transport

Climate Impacts, e.g., impacts of climate change to environmental containment systems, remediation systems.

Bio-Inspired & Bio-Mediated Geotechnics, e.g., hazard mitigation, dust suppression, vegetation in sustainable management of slopes, environmental protection and restoration.

Energy Geotechnics, e.g., energy geo-storage and geo-structures, energy pile
