Geomorphologic engineering

The thermal state of the soil, its frost susceptibility and its freezing and thawing conditions dictate the geotechnical behavior of soils in the periglacial environment. The Geocryolab focuses in on the role of water and the freeze/thaw process and their impact on soil properties and behavior. Main processes and characteristics to which attention is given are frost heave and settlement, water flows, soil erosion and slope stability. The geomorphological approach is ideal for early investigations leading to an extensive understanding of spatial and environmental changes in permafrost conditions, properties and reactions to disturbances. By focusing on geomorphological units and landforms, we can produce results predicting typical reactions of the landscape to changes in thermal conditions of the soil induced by infrastructures, snow coverage variations and/or climatic changes.
