Heavy irrigation on a hillslope will cause __.

Question

Quizplus · Accepted Answer

Heavy irrigation on a hillslope increases the pore-fluid pressure as water infiltrates the soil, adding to the weight of the slope due to the added water. This increase in weight and pore-fluid pressure can decrease the shear strength of the slope materials, making them more susceptible to movement. Additionally, the added weight increases the shear force/stress acting on potential slip surfaces within the slope, contributing to slope instability.
