Transcribed Image Text:SITUATION: The coefficient of permeability below a dam is 4m/day. The water on the upstream
side is 20m higher than on the downstream side. To estimate the seepage below the dam, a
flownet was graphically drawn such that the number of potential drops Nd%310 and number of
flow channels Nf=4. The base of the dam is founded 1m below the ground. Between the heel
and the toe of the dam, a distance of 30m, there are 8 potential drops. Determine the uplift
pressure at the heel of the dam in kPa.
