Question

You were assigned to describe the pore water pressure in Figure 1. It shows the cross-section
of a homogenous compacted earth dam highlighting the flow behavior. Excessive rainfall has
saturated the embankment. Given the three points A, B and C.

A. Which of the points will have the highest positive pore water pressure?
B. Which of the points will have the lowest positive pore water pressure?

Figure 1 shows the cross-section of a homogeneous compacted earth dam highlighting the flow
behavior. Note three points: A, B and C. At which one of these points would you have the highest
positive pore-water pressure?
1
Excessive rainfall
( surface flux)
Phreatic surface
Water level
