A river is 6 m deep. The riverbed material has a saturated unit weight of 19.5kN/m3.
What is the effective vertical stress 12 m below the water surface?
Consider again the scenario above. Assume the water is static. Assume a datum at the water surface.
a) What is the total head 5.0m below the river bed?
b) What is the pore water pressure at that level?
