Reduction of soil suction limit (Psiunsat) leads to slower groundwater flow in unsaturated slope

Haifeng Zou

I am simulating the process of pipe burst induced groundwater flow in an unsaturated slope (see simplified sketch in Figure 1 below). According to the according to the k-function curve, a lower limit of soil suction will make the soil more permeable at…
