4.2.8 Embankment Dam Analysis-phreatic line and seepage analysis
Determine the specific discharge for the earthen dam having 33 m total height with 3m width impervious central core. Take top width of the dam is 7m and freeboard 3m. The coefficient of permeability of dam material is 4×10⁻⁶ m/sec and that of impervious core is 4×10⁻⁸ m/sec. The upstream and downstream slope of the dam is 3:1 and 2.5:1 respectively. [5]
