The simulation demonstrates how rising pore-water pressure in a thawing active layer above frozen ground causes saturated soil to deform and creep downslope into characteristic lobed forms.
Adjust the pore-water pressure, slope gradient, and freeze-thaw cycle speed sliders, then run the simulation to observe how quickly and in what shape the solifluction lobes advance downslope.
Sliders for pore-water pressure, slope gradient, and freeze-thaw cycle rate
Some solifluction lobes in Arctic Scandinavia and Alaska have been creeping along essentially the same track for thousands of years, moving only a few meters in total despite continuous seasonal activity.
