A drying out in soils

It is the process of forming polygonal cracks in compact soil by losing water and moisture in periods of drought. Desiccation cracks mostly affect clay soils. Shrinkage of these soils can lead to the formation of cracks up to 4 cm wide and more than 1 m deep. The deep action of temperature changes and other atmospheric agents can then be the cause of subsequent landslides. They also play a role in the formation of polygonal soils and in creep phenomena.
