In the boundary effect stage almost all the soil pores are filled with water. The
soil is essentially saturated at this stage, and there is no reduction in the area of water in this
stage. The soil starts to desaturate at the air-entry value in the transition stage. The air-entry
value identifies the point at which air enters the largest pores of the soil. The water content in
the soil reduces significantly with increasing suction in this stage. Eventually large increases
in suction produce only relative small changes in water content. This stage is referred to as
the residual stage of unsaturation.
Impact of moisture changes in unsaturated soil engineering applications俄克拉荷马大学2016博士论文
In the majority of slopes located in Oklahoma, the soil mass is in an unsaturated state within the active zone; the active zone is defined as the depth of soil over which moisture content fluctuates due to seasonal weather.
