A novel equation for determining the suction stress of unsaturated soils from the water retention curve based on wetted surface area in pores

A novel equation is proposed for the evaluation of the suction stress of an unsaturated soil. The equation, based on the assumption that suction is transmitted to soil solid particles only through their wet external surface, allows to easily derive the soil suction characteristic curve from the wate...
