Question

The following figure shows an earthen dam with a reservoir depth of 60 feet. Undermeath the dam is a 50-foot thick uniform pervious soil layer that is underlain by impervious soil. Water flows through and beneath the dam and drains into a filter and drain system. The embankment material and underlying soil both have a hydraulic conductivity (k) of 1X10 cm/sec. 2. a. Compute the seepage through the dam (per foot of dam) in f'/day. (Note: 1 foot 30.48 cm, 1 day 86,400 sec) (9 points) b. Compute the pore pressure at point A in psf.
