Use the Dupuit method to construct the upper flow boundary of
seeping water through the dam shown in Figure with 20ft of upstream
water. There is a 7.5ft toe filter with 5ft of downstream water.
The unit weight of permeability of the dam material are 100pcf and
1.0*10^{-7}cm/sec respectively. Calculate the seepage loss
and effective stress at a point 40ft from the toe of the dam at the
bottom most point of the dam.
