– It involves the slow flow of water-saturated soil down a slope. This occurs when the surface layer of soil (active layer) thaws in summer but is underlain by impermeable permafrost, preventing drainage and causing the soil to become saturated and mobile.
– While slow mass movement (creep) can occur in various environments, solifluction specifically refers to the saturated flow condition over a frozen layer and is characteristic of permafrost environments or places with seasonal ground freezing that mimics the effect.
