4.2.8 Embankment Dam Analysis-phreatic line and seepage analysis
Determine the seepage line for a homogeneous earthen dam of height 22 m and top width 6 m retaining 20 m depth of water in the reservoir. The slope of the upstream and downstream faces of the dam is 45°. Also determine the seepage discharge, if the length of the dam is 3 km and the value of the coefficient of permeability of the dam material is 3×10⁻³ mm/s. [10]
