4.2.8 Embankment Dam Analysis-phreatic line and seepage analysis
A homogeneous earthen dam has the following data: Dam crest level = 300.00masl; Deepest river bed level = 278.00masl; HFL in the reservoir = 297.50masl; Dam crest width = 4.50m; Dam u/s slope = 3:1; Dam d/s slope = 2:1 and coefficient of permeability of the dam material = 5×10⁻⁴ cm/s. Determine the phreatic line of the dam section and the discharge passing through the dam. [4+4]
