Hamed Khodadadi T.

Dear Mehrdad

difference between drying and wetting path (air entrapment effect) is function of soil size, shape and type. see the following link:

Dear Hamed

thank you so much.

Bappa Das

The phenomenon of hysteresis is pronounced in soils with pronounced swell-shrink capacity, or in clayey soils containing predominantly 2:1 clay minerals.

Dear Bappa, this phenomenon occur in all of the soils but is not similar in different soils.
