Permafrost degradation illustration

Caption

This diagram models half a road in cross-section from the road center to the adjacent tundra. The graphic illustrates the subdivision into four structural units (road center, shoulder, toe and tundra). The grayish area with black dots represents the road embankment. The light blue shading indicates potential maximum snow height. The dark blue area illustrates ponding next to the road.
