Which risk increases for tundra civil engineering projects when permafrost thawing enhances solifluction?

💡 Explanation

Slope failures are more likely because increased water content within the active layer from permafrost thaw reduces soil shear strength, enhancing solifluction flow events. Therefore, infrastructure experiences instability from soil creep rather than other greenhouse or ecological effects.
