Exercise 1
Compute the total stress, vertical effective stress, and water pore pressure at a depth of 15 m below the bottom of a 6 m deep lake. The soil below the lake bottom consists of soft clay with a thickness of more than 15 m (Figure Exercise 1‑1). The clay porosity is 40 percent and the specific weight of soil is 2700 kg/m3. How will the effective stress change if the water level in the lake drops to 4 m?
